Breaking news, Frank Colver found most special slide scanned up to photo for Lift:

I just bought a scanner, so here it is, the classic photo. Richard Miller sitting and watching my assembly process while my son Matt looks on also. I'm glad I stopped long enough to take a photo.

This was on a hill near Vista, on Twin Oaks Valley Road, that Richard called the "vineyard hill" because it was the site of an abandoned vineyard. We also called it the "water tank hill" because it had one of those at the top. There is now a golf course at the base of the hill which has been cut into a high vertical bank. There were Indian grinding holes in the rock on this hill.

Wish I could show this photo to Richard :-(

See you tomorrow,

The only injury reported concerning the first Otto Meet was by Frank's daughter Laura:

When I broke my toe, I wasn't trying to fly, I was trying to dance! What can I say, the hills were alive with music :o)

While Jonathan was reaching for the Otto Party, he decided to fly:   HERE
Yes, here is the list concerning the 2011 Otto Marker event, Michael.

I get a feeling I have missed one person.

The Privitt family was large at original meet and large at this 2011 commemoration.

Again, special thanks to the follow-up leadership stepped by Bob Kuczewski and Margie Holland that brought the actual marker to be physically effected.

By proxy Ernest Feher sent a person to represent himself: John Rittenhouse. Ernest was calling in from China. Ernest was an original Otto-meet attendee.

Otto Meet Marker Project founder:
Neil Larson could not get in from Florida. He had been the strong first returnee in 2008 to begin the project. He has done substantial work on the project since 2008. He was a young teen totally enthralled with what he saw in 1971; his interest has not waned. He is primary historian for Jack Lambie; he was our first official SCHGA and USHGA historian. He was totally present in spirit at San Miguel Park.

By proxy I represented Jonathan who was intending taking video of the event, but by special dust devil was physically prevented from being present.

Many others expressed strong spirited presence for the 2011 party. And I noticed the wings of Richard Miller and Jack Lambie and Lloyd Licher in that flock of crows that circled above our Monday meeting ...

Otto's Birthday 163rd. 
Otto Meet Marker! May 23, 2011:
The 40th Anniversary of the birth of worldwide sport hang gliding!

On this site, May 23, 1971,
with a gathering of enthusiasts
for personal human flight, began
the worldwide sport of hang gliding.

Celebration gathering at the original site will occur at noon.
Daily Pilot reporter will be covering the celebration.
Much thanks for the idea, research, project chairmanship since 2008 by Neil Larson:
attendee of the first birthday party and first official historian of worldwide sport hang gliding.
Contemporary hang glider US Hawks president Bob Kuczewski  and Margi Holland have gifted the stone and etching for granite stone.

Genesis for the marker project that is coming to blossom wings:
This was a dream in my head on Thanksgiving Day Weekend 2008 I drove for family reunion to from Florida 2200 mile straight through to Inglewood – Hollywood park Race Track on Friday after a 32 hour cruise
- Saturday Night I stayed at the Atrium Hotel in Newport Beach –
Sunday Morning I “reconed” the whole Hillside area –
Taking photos & videos –

What went on in my brain was a very spiritual self-lifting epiphany –
With a very transcendental peace about the first hang glider “meet”
And the hillside where I was walking- for me it became almost a
Holy pilgrimage of sorts , knowing who had stood on that hillside-
A very elite group of people known to a very few select hang gliding & flying enthusiasts –
What I desperately wanted to share with everyone in that community was the grand feeling I had on May 23rd, 1971 – to witness history
Later that day Sunday – November 30, 2008 – I had a Reunion with my family at my cousin’s house in Laguna Hills about 40 minutes south of Newport-

My desire to share the feeling is still deep inside, perhaps this will help to
Enlighten others about the beginnings of our wonderful sport –
Thank You Everyone –
I feel this is a first step/
Perhaps , one day a metal-sculpted statue of a man wearing thick
Ray Ban sunglasses up to his arm pits in hang glider
Will adorn this park –

I saw that in my dream….

The announcement following considerable committee exchanges:

=================================================
At the San Miguel public park in Newport Beach, California,
on May 23rd, 2011,  in tribute to and celebration of the 163rd birthday of Otto Lilienthal,  and the 40th Anniversary celebrating
the birth of worldwide sport hang gliding will be celebrated
at noon.

There will be some personal flight enthusiasts recalling the
birth of worldwide sport hang gliding --
an event which took place on the Pacific hillside 40 years
ago on May 23, 1971.
The now Historic 1971 "Happening" which has become known as
the Great Universal Hang Glider Championships has become the
pivotal event marking the beginning of a persistent growth
in the individual human flight sport known as hang gliding.

The event of 1971 was featured on the front page of the
May 24th Monday morning edition of the Los Angeles Times,
recalled later also by a Daily Pilot's reporter as a
singular important gathering of hang gliders, birdmen,
along with hundreds of spectators, and local residents.
National Geographic also featured the event in an article
for the world. This is a Benchmark event in the local
history of Newport Beach, Orange County, and California. It has
become an important focal point on the timeline of human
aviation as well.

Now some 40 years on...    In 2011 the celebration of the 163rd
birthday of Otto Lilienthal and the 40th anniversary for the
birth of worldwide sport hang gliding will be celebrated at
noon, Monday, May 23, 2011.
=====================================
It is suspected that some people from various sectors of
contemporary hang gliding will be present to enjoy the
honoring of this historic event. The gathering on May23rd 2011 will include aircraft builders and pilots of hang gliders that flew that day, and witnesses to the original Otto Lilienthal's 123rd Birthday Party of 1971.

An engraved granite marker stone will be presented to
someone of Newport Beach community as a humble token to
the local residents that their community was the location of
the very first competitive (multiple entries) hang glider
meet. Up until that day, there had never been such a
gathering of personal aircraft assembled and flown at one
location. The Inscribed Marker Stone is being presented
with the hope the City of Newport Beach will permanently
display the stone in a conspicuous place on San Miguel Park,
to bring recognition of this event. Over the 40 years Hang
Gliding has proven to become a very significant recreational
sport; the people of Newport Beach should be proud of such
auspicious heritage.

All Media - is encouraged to take advantage of this
commemoration of the birth of modern sport hang gliding.
The gathering of hang glider enthusiasts on this hillside
has not happened here since that day on May 23 1971.
As this event draws closer, it is possible nationwide media
coverage will provide public exposure of the day's event.
A photograph of a poster of a year 2000 reunion of hang
gliders will be viewable.

[Note to those who visit: There is no permission obtained
for opening or showing of hang gliders
in respect of the residential neighborhood that has been
established.]

Dear pilot:

We are pleased to announce that we are able to offer for sale the “Cigüeña” to tow hang gliders. It has passed all the tests, very successful, with beginner and intermediate hang gliders, has not yet been tested with advanced gliders, but we will soon.

The sale price is € 6500 (six thousand five hundred euro) .Engine and propeller are not included. Transport costs and tax rates are the responsibility of the buyer.
As you know this is an invention worldwide, so no one able to advice on the management of the flight, which is why these first units will be sold at the moment, in Argentina. This way you also have the privilege to see, learn and be towed by the prototype, ultimately, be the protagonist of this great event.
At this time we are sending this email to those pilots who expressed interest in this new method for hang gliding.

Any questions, feel free to contact us.

Best regards,

Hang-line shock-absorption?

The majority of hang gliders in use employ a tether set (set of hang lines or risers) that couples the resistive pilot mass with the system's wing (a kite system).
Respecting that solutions will differ per type of hang gliding activity, how much hang-line shock absorption would be good to meet purposes of

  • safety?
  • utilization of lift?
  • life of the hang glider?

What studies have been made?

  • Consider extremes.
  • Low-stretch tether connecting pilot and his or her wing provides some pilots with useful flight information; could target information be obtained in some other way if much more stretch is built into the tether set? 
  • How would the information change if the stretch is large?
  • Consider selectable levels of shock absorption.
  • Rebound rate?
  • Consider selectable levels of shock absorption. Trigger in a select amount of shock absorption for launch and landing time sectors.
  • v?

s2o

Furthering:

Cragin S,
Thanks. Some of both. The scores of niche hang gliding activities have some deliberate circumstances that might invite some attention on shock absorption in the tether set. Some furthering setting the scene for the topic is in my notes below to Christian Williams. The bungee cord mention is a natural first offer, but depending on needs, the matter could go further with designer bungee cords; more: other springs with ratchets, friction slips with no return rebound, hydraulic items, energy gathering flywheels with controls, etc. Upon facing a niche HG challenge, the design could come next.
In facing the gust soaring of focus by Gary Osoba and Taras Kiceniuk, what might be the optimal tether set to work the gust soaring?

In facing flight-cable total-stress history, what contribution comes from the tether set's response to shock loads? Would specific choice of tether set characteristics keep integrity to the flight cables and fittings longer than very-low stretch tether sets? Given choices of tether sets for nich activity, how would one select among the choices?


Christian Williams,
Initial post holds an aim to include the many types of tether sets that occur in kite hang gliders in distinction from those arrangements not using any hang lines. The topic would respect tether sets of counts of say 10 or 9 or 8 … etc. or 1 as your hang strap. Each set has a non-zero elongation under shock loads. Each set elongates at a certain rate. And each set will have its own return or rebound from zero to some positive amount (or let breaking be negative return or rebound). Your replacement to a hang strap resulted in having a certain amount of elongation and perhaps rebound. Most commonly pilots are not installing delayed rebound tether sets …more than the delay that is belonging to the tether set materials themselves; say not having ratchet grabs to prevent immediate rebound.
And, the initial post intended to set the scene for seeing the tether-set hang gliders as definte kite systems that experience at times sharp loads that add to the total stress history of the hang glider and pilot. In some niche activity there are deliberate high-cycling of smashing landings that invite shock-absorption questions (one niche HG activity is flat-land long gliding (FLLG) combined perhaps with an anti-whack ski set integrated with flying canard skid wing.
http://ozreport.com/forum/viewtopic.php?p=97750#97750
shows a sketch. In such activity one mode of practice intends ski landing on the flats with more assurance of non-rotation of keel; therein one might want to have stretch of tether set members without any rebounding.

Another niche HG activity: Asphalt streets of downslope landing plannings with intent of landing on skids in combination with anti-whack frontal low skid. The asphalt street does not have much "give" and the ski can be with a spring cushioning. Further, absorping some of the landing shock via the tether set could possible give longer life to flying cable and fittings and other HG parts. And further, damped loading at landing could be reduced in some niche activity by having the tether set members elongate under landing loads without rebound (thus not simple bungee).

Some perching activity might invite one-way shock absorbing where grabing claws on TCF basebar snap closed on wires or branches while the pilot is cushioned by the one-way non-rebound of a specially designed tether set (reset for next flight could be in the design).

The concept of cruise with one setting for a tether set and landing with another setting for a tether set is on the topic table also. One may want a stiffer setting when facing certain airs; and then upon entering the landing sector of flight, select another setting for the tether set.

Thanks to both of you for the synergy.

JoeF
PS: …edits upon waking on next day:
== letting tether set alternating lengthening and shortening be a source of electricity generation; use electricity for charging batteries for camera, instruments, warmer, propeller's motor …
---------------------------------
==Ski face might be rotatable; and a braking of that face might be controllable. Or in some niche applications the ski face and lower frontal canard wing skid face might have ablative material that the pilot could replace for repetitive landings. In some niche activity pilots may emphasize use of nets, drogue chutes, arrestor lines, or special perchings.
----------------------------------
== Strategic lengthing of the tether set without rebound might be combined with other braking systems, and even coupled with the lengthing action caused by pilot-mass relative position with respect to TCF.
-----------------------------------
== With the referred sketch of the TCF with ski and frontal flying canard wing skid, there might be a limit line to pilot torso that prevents vertical rising of the chest as the pilot moves forward some.
----------------------------------
== For particular niche HG activity, there will be reasons for selecting a specific tether-set with its particular characteristics. The challenge in part is to attain comprehensive awareness for having used designs. In some niche HG activity there might be good reasons for having an advanced shock absorption tether set; when so, then the challenge of design begins to play. Altered position, rebound or not, safety factors, trade-offs, costs, return on investment, operation and maintenance, inspection, experience, activity allowance, etc. will play into developments.
-----------------------------------
== Each currently-offered harness system with integrated hang loops, carabiner, and completing tether set has a shock-absorbing scene that might be measured and specified in product releases. Incorporation of a select product in a specific HG with a specific loading will result in a specific shock-absorption profile. That profile could be well described. And changes to the profile could be a matter of care.
-----------------------------------
== These matters might affect competition flying. Would a change in the shock-absorption system affect the outcome of a competition? Efficiency in handling gusts, lift, challenges of endurance, …? What degree of shock damping would result in best competition results? What system of shock damping would result in best competition results?
-----------------------------------
== In search of opportunity, safety, efficiency, awareness, activity choice, fun, accurate specification for harness systems, accurate specification of shock absorption profile of harness systems, perching systems, landing options,  shock history recording, How much did that shock event cost?, Could damping heat route to warm pilot?,

Joe Evens,
You are invited to consider some point of the discussion and keep it simple, but not simpler than needed to meet some specified target purpose.

Could your ATOS flights be of a higher quality with a modified shock absorption system other than that which you have used?   In a 3 hr flight, could the quality of the flight be altered to a gain by a change in your shock-absorption system?
JoeF

PS:
Wiki share:  It can scarcely be denied that the supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience.

Head and neck
What have we and what has been and what could be?
Hang gliders' heads and necks? Helmets add mass and thus inertia during operations of launch, flight, and landing.
Sudden knocks and stops. Tendons, bones, nerves? Abuse, misuse? What is the record of neck injuries in HG?
Mitigations? Unwanted meetings with TCF tubes and keel? Fatigue? Yes, good pilotage, but then how many incidents
does it take to change a life? Stories? What could have prevented the injury; and what else could have prevented
the injury…? Head and neck in focus! Clothes, devices, harnesses, lines, helmet designs, holders, braces, fillers?
What have we? At launching, during flights, at landings, and at carries?  (posted in OR on May 19, 2011, by JpF).

When bringing a HG to perch on a high cable using snap-close claws, one might want to trigger into play
a pilot-mass non-rebound shock-absorption capability to coordinate with the perching operation.

  Part of the attention on joined wings that is arriving from Alex Morillo's leads and fine project as reported in LIFT, we also have special interest in Tony Prentice's  project.  Along the way Tony notices:

Building Synergy

Tony notes: Hi Alex & Joe,
This video gives details of an aircraft project called Synergy. The project is being discussed on the Homebuilt Aircraft group. http://youtu.be/lpMzb3DdFEA

It shows how vortex energy is re-directed via the tip to the rear wing section. It is much the same as my Halo ring wing project so there seems to be possible merit in the idea.

Tony               May 6, 2011

There are others working on similar lines as with the 70 kg  USD $39,000 FlyNano Electric Microlight

It would be interesting to have wind tunnel tests done to see how the vortex is modified with this type of wing arrangement.

 The letters from Richard Miller are priceless to me. In one letter he has figured out that my CG is too far aft in my Skysail. He was right! The wing was "mushing" and we didn't realize it. Richard and I used to talk for hours about his dream to have a wing where the pilot could physically feel everything going on out in the wings - like a bird can. At the time it seemed impossible, but now with the developing field of bioelectronics and super miniaturization I can visualize it happening some day.

Further down in the Pop Sci article it shows Chuck Hollinger's wing. I don't know if you knew that Chuck died suddenly a couple of years ago. I had recently re-established contact with him through my re-entry into R/C gliders and R/C electric models. We flew models at the same field. His wing was an amazing performer but it never got much press. I wonder if it is still in his garage where it was before his death.

Frank
Re: Chuck Hollinger, quote in the above linked bio by Hank Cole::

[ Charles Hollinger ]

He designed an airfoil for a flying wing hang glider (while not a model the technique here is important), which he built and flew in (as a grandpa!). In order to find out if the pitching moment was positive, he built a model of the airfoil, ballasted it so it would not float, and gave it a little push under water in the bathtub to make sure it was stable!   Source.

    Discuss toward HG
    "Performance" as descriptor can be abused or a wonderful door for creative individual niche appreciation.   Discussion is open.

    "Performance"
    What is in this term in HG? What factors, parameters, aspects, nuances, … make up "performance" of a hang glider system?
    For you?
    For your niche HG activity?
    ============================================

    "Performance" as descriptor can be abused or be a wonderful door for creative individual niche appreciation.
    Discussion is open.

    • SkyWings just let be published a statement by its editor:  "... at the 1971 Otto Lilienthal rally in California. Performance [of the Hang Loose biplane types] was much poorer than the Rogallo-based wings."  One may take severe issue with such statement depending on interpretation of "performance." At the rally one of the leading Rogallo types succumbed to using long kite-string launching tactic.  Some of the biplane HGs had L/D superior to the Rogallos, but control and practiced control was challenging.
    • Not-a-Rogallo was the Conduit Condor flying wing that had superb foot-launch gliding and control by Richard Miller, superior in performance to the biplanes and Rogallos.

    Limit line loop (3L) using two pulleys, gather elastics, harness connections: limits distance forward, backward, upward, left, and right ... while permitting pilot-control positions as needed. The 3L system protects neck from head hitting keel above or forward during launch, landing, flying, inversion, tumbling, .... Weight of glider can rest on hips while standing with glider.  Loop section may be exterior to basebar or interior to basebar.   

    Combine 3L with frontal flying canard skid and ski system, if wanted.

    FLIGHT, 23 March 1961, page 359.   Note that consider work was done prior to the article's date in order to come up to the contract stage that was being announced.

    A "w" was added to Francis M. Rogallo's name in the article; so, yet another variant of misspellings:  "Rogallow"

    Ryan's Flex Wing
    IT was announced on March 8 that the US Army Transportation
    Research Command have awarded the Aerospace Division of'
    Ryan Aeronautical Co a contract for the flight testing of a powered
    test vehicle for the Flex Wing.  Based on studies pioneered by
    Francis M. Rogallow of NASA's Langley Research Center, the
    Flex Wing consists of a triangular membrane attached to sharply
    swept leading edges and a central keel, each of which may be
    rigid or inflatable.  The complete assembly can be folded into a
    small package, yet deployed faster than a parachute, when it
    assumes the form of a pair of conical surfaces side-by-side, flying
    point-first--like a paper dart.
       Ryan are so encouraged by their research that the concept
    appears likely to have wide applications. Configurations have been
    tested, both in free flight and in tunnels, from sea level to 200,000 ft
    and from low speeds up to M4.9. Immediate applications include
    the lifting of utility aircraft, manned or unmanned payload carriers,
    towed gliders and emergency wings for V/STOL vehicles. Indicative
    of the work being done is the free-flight testing of an unusually
    manoeuvrable radio-controlled 5 ft model with a 1.5 h.p. engine,
    the fact that a Boeing-Vertol H-21 helicopter can tow an 18,000 lb
    load supported by a Flex wing without reduction in speed, and
    that Ryan have received a NASA study contract for Flex-Wing
    recover of the first stage of the Saturn booster.

    Hi Folks. As fellow flyers, may I just bring this to your attention. Thanks.
    Dunge Bottom: Tales Of An Unconventional Aviator
    The new book by John Clarke that is attracting 5 star Amazon reviews. A must buy for all hang gliding and ultralight enthusiasts!
    "If this doesn't raise a smile I don't know what will"
    "Read from start to finish in one day"
    "Satisfying read for any and all"
    Available from Amazon.com, Amazon.co.uk and www.crookedhatpublishing.com

    Bleriot, Lindbergh, Johnson. Now the name Clarke is set to join the pantheon of flying legends.
    Forty years ago hang gliding and microlighting were in their infancy. They were sports dominated by adventurers, eccentrics and the occasional lunatic. Participants developed and flew their own aircraft designs, the attrition rate was high but still these brave men and women were united in their passion for flying and their determination to get off the ground. One such man was John Clarke. Bored with his life as a Quantity Surveyor and determined to be the kind of man his wife had just run off with (but lacking the physique to be a part time wrestler) he built his own craft and took to the skies. His subsequent adventures provided answers to many of life's questions including:
    Can one survive a freefall in a micro light from five hundred feet?
    Do the French cheat at everything?
    Can dogs hang glide?
    Can you find love during intensive Physiotherapy?
    John Clarke is a former hang gliding and microlight instructor who for twenty eight years owned the Peak School of Hang Gliding in Wetton, Derbyshire. Dunge Bottom is the story of his early life in amateur aviation, the triumphs, disasters and often hilarious events that he took part in and witnessed. The stories embody the best of British eccentricity and adventure, guaranteed to make you want to take to the skies.

    Dear FAI News Readers,

    For the first time in its history, the FAI will have three sports present at the World Games. Both Canopy Piloting (Parachuting) and Accuracy Landing (Paragliding) feature in the competition programme of the 2013 World Games that will take place in Cali, Colombia. Indoor AeroMusicals (Aeromodelling) is included in the programme as a demonstration sport.

    “Paragliding Accuracy Landing and Indoor Aeromusicals will make their debut at the IWGA World Games which will be a great opportunity for thousands of people to discover these fantastic sports. All the more as they have been designed to be spectacular, media friendly and easy to understand for anyone who watches them for the first time. As for Canopy Piloting, it was already present at the 2009 World Games in Kaohsiung and I am sure that it will once again wow the crowds,” said Jean-Marc Badan, FAI Sports and Development Director.

    Canopy Piloting involves a series of tasks designed to test a parachutist’s ability to control his canopy and fly accurately. Pilots compete over a stretch of water for safety reasons because of the high speeds involved - at the same time creating spectacular action as the parachutists whizz across the surface of the water, leaving a plume of spray behind them.

    Accuracy Landing is a test of the paraglider pilot’s ability to fly their canopy to a very small target landing pad. Pilots launch from a hill or with a ground-based winch and fly their paragliders to the target positioned in front of the public, which makes the competition exciting for all the spectators.

    Indoor AeroMusicals is a combination of complex aerobatic sequences performed in harmony with accompanying music, creating a free style aerobatic sequence which conveys the mood of the music.

    Kind regards,

    --

    [[Canopy piloting (parachuting) and also Accuracy Landing (paragliding) are sectors of kiting and also sectors of hang gliding. Kiting is the superset; in canopy piloting and paragliding, the tether set is tensed by the two opposing wings: human pilot as one wing and the canopy wing as the other wing; these sorts of kiting are in free flight, except during landing (and launch for the paragliders).  ~JpF  May 17, 2011]]

    Please consider researching the flight by Maude Oldershaw on

    September 22, 1977, perhaps the first woman-powered flight.

     
    The author Morton Grosser wrote in Gossamer Odyssey: The Triumph of Human-Powered Flight,   "..., but it was Maude that everyone was watching. Maude was due to have her sixtieth birthday in a few days; she was a pilot, a civil service examination administrator, and a grandmother ten times, and she had endeared herself to every person on the project. She was installed ceremoniously in the Condor's cockpit, and with the aplomb that she knew the team expected, she took off and flew, laughing for most of the flight, and landed beautifully. As she later told Lin Burke when her turn to fly the airplane came, "Go on, you can ot it ...it's easy1"
     
    There might be video for timing counts. AeroVironment archives? Bill Watson? Taras Kiceniuk, Jr. ?

    Duration of her flight?  Gamera is of a fully different sort of design with its four rotary pairs of wings.

    Does Maude's flight affect the current FAI record claim?
     FAI has received the following Class I (Manpowered aircraft) World record claim:
    ================================================
    Claim number : 16230 and 16232 (feminine)
    Sub-class :I-E (Manpowered rotorcraft)
    Category: General
    Type of record : Duration
    Course/location : College Park, MD (USA)
    Performance : 10 sec
    Pilot : Judith R. WEXLER (USA)
    Aircraft : Gamera
    Date :12.05.2011
    Current record : no record set yet

    CAFE Symposium Celebrates 'Dawn of Electric Flight'
    The CAFE Electric Aircraft Symposium, held at the end of April, was packed with so many new airplanes and concepts that it was like seeing 30 college lectures in two days, as the information came fast and furious. In the opening remarks, CAFE President Dr. Brien Seeley dubbed the 2011 event "the dawn of electric flight," citing there has been "exponential growth" since the first symposium in 2007. Experimenter Editor Pat Panzera was there to see it all and filed a two-part report that covers the cool new planes that are competing in the Green Flight Challenge and EAA's Electric Flight Prize, as well as promising new technologies which will reach far beyond aviation.

    When in HG flight, if ever, would it be better to release from the wing entirely
    instead of coming down with the wing?
