  • I've just discovered a 1935 Chanute style hang glider, the Sablier 8, typical Chanute wings, but only 15'9" span, two sets of longerons, and "olde worlde" frilly trailing edges to the tail surfaces, I reckon it would have been retro in the 1930's    http://tinyurl.com/plansOnSablier8Biplane       Note from Kevin Brown,  Jul 4, 2011.
  • Research note by Kevin B, 3Jul2013
    • "Just a quick update to the Sablier plans.

      I've started to translate them, and you are very right in it needing a sympathetic translation, as Google translate gives only a rough idea of what is being said; but anyhow, the type 8 is the original 1922 glider and a detailed 3-view is on the first page of the construction plans; the rest of the plans are the Sport from 1932. Sablier just did detail changes to the original and re-released them ?? in 1932, the changes are simply trailing edge and centre section struts, the trailing edges on the 1922 type 8 are square at the ends, and the struts are inclined, whereas the 1932 type Sport has angled T.E.s at the ends and square struts at the centre section.

      Sablier also seems to be saying that an engine and undercarriage was considered because of the robustness of the structure, but as this would make it an aeroplane, the idea wasn't pursued. The layout he mentioned had the engine mounted to the lower wing centre section, leading edge, like the Richter, but which came first ????.

      I'm also collecting data on another little French Chanute type, the plan was published in 1941, (not sure if that would be occupied or Vichy France, or both), and appeared in a French version of Aeromodeller magazine, the author "Max Williams" seems very serious about it.............interesting !!

Some reporting:  http://www.cometclones.com/mythology2011.htm

Human-powered flight has its gliding moments and meaning! The gliding sectors have mechanical implications over the hang gliding historical feathers.  Exploration of muscle-powered efforts does not diminish the impacts over the gliding dimensions of the efforts; when muscle effort is lowered or stopped, then gliding worlds begin.  Examine the mechanics of craft used in human-powered efforts for delightful insights to the gliding worlds.    What have we?  
How disruptive would success for the electron-only battery that is being explored by Stanford U.  group?   Contact person: Prof. Fritz Prinz

Project Title The All-Electron Battery: a quantum leap forward in energy storage
Organization Stanford University
Website http://www.stanford.edu/
Point of
Prof. Fritz Prinz
In this project, researchers Stanford University will seek to develop an "All-Electron
Battery", a completely new class of electrical energy storage devices for electric
vehicles that has the potential to provide ultra-high energy and power densities, while
enabling extremely high cycle life. The All-Electron Battery stores energy by moving
electrons, rather than ions, and uses electron/hole redox instead of capacitive
polarization of a double-layer. This technology uses a novel architecture that has
potential for very high energy density because it decouples the two functions of
capacitors: charge separation and breakdown strength. If successful, this project will
develop a completely new paradigm in energy storage for electrified vehicles that
could revolutionize the electric vehicle industry and establish U.S. leadership in
advanced energy storage technology for electric vehicles.

Perhaps it is now time for frame-controlled hang gliders
to have associations solely dedicated to their sport.

What do you think? 

How is your national association handling the PG question?
Will coming restrictions on PG affect frame-controlled hang gliding?
Ryan Voight shares: 
It's getting pretty short notice (end of the month), but as you may or may not know, every year I run an aerobatics clinic here in Utah. It can be anything from an intro-to-aerobatics for H3+ pilots that want to learn safely, to an improvement clinic for people that are already doing aero.
More info here: http://www.wingsoverwasatch.com/Clinics/Aerobatics2011.html
But the big news is that Aaron Swepston has agreed to come and help coach us! The catch is that we don't quite have enough people signed up yet. I actually only have ONE signup so far. If we can get four people (so three more), Aaron will come down and we get to have some fun.
The clinic is open to anyone with a H3 rating. If you have questions, feel free to PM me. I'm going to have to make a go/no-go call fairly soon, so if it's something you want to do, this is the time to register!

Hang Gliding on the Treetops

We (NASA LaRC) are experimenting this summer with wire cut EPP foam arc kites with various different coatings. EPP is relatively cheap, can be recycled, and very tolerant of “unscheduled landings” and we believe can perform fully-autonomous re-launch from a water surface. The EPP holds a very nice profile tolerance compared to the not very good profile tolerance of a ram air kite. We are able to produce foils with good thickness-to-chord ratios (8%) and aspect ratios of up to 20. Our goal is to improve L/D from 3-8 for current ram air kites to maybe 10-12 which would improve specific power output (power/kite area) by up to a factor of ~8. 

The EPP foam is a solution that is mid-way between a soft wing and rigid wing that has benefits of both. 

We are building a servo motor controlled kite flying system that can measure kite speed, trajectory, line forces, and line speed and should be producing data within a few weeks. 

We are also doing some experiments with a simplified optical tracking system that uses only one or two (cheap) cameras for flight control. No control system instrumentation onboard the two-line kite (no GPS, no IMUs, no gyros, no telemetry).  

Stay tuned. Will keep you all informed of progress.

  • Popular Science Monthly, October, 1930, page 19.  American ~ Unknown to Fame First Man on Record to Leave Earth on Wings  by Robert Martin:  

     "The man usually spoken of as the trail blazer of gliding is Otto Lilienthal. Yet in 1884, a full seven years before this great German pioneer got into the air, John J. Montgomery, a lonely and misunderstood twenty-six-year-old experimenter, sailed for 600 feet down a hillside near Otay, riding a homemade monoplane patterned after a gull."  ... "Born February 15, 1858, at Yuba City, Calif., the first of twins."   ...""Long before he could make his own kites, he begged his mother to make them for him."

      Special note by Robert Martin in the 1930 article: "In his famous book, Progress of Flying Machines," published in 1894, Octave Chanute reports Montgomery's success, as does Victor Lougheed, former Secretary of the National Aeronautic Association, in his Vehicles of the Air. Singularly enough, many later histories of aviation give Montgomery scant space and some omit his name altogether."
    • Second machine was heavier. 1885.  Flat wings; not good  (his first glider had curved-chorded wings).
    • Then after a period of experimentation following professional growth: The April 29, 1905 flight with "Santa Clara" was a glider made of two monoplanes set in tandem position. Author is using term "tandem monoplane."     Maloney, "known to fame as Professor Lascelles" ...
      Height estimates to be taken as rough estimates.    Travel path: 8 miles.  Landed glider safely in mild outlanding. Dan Maloney.  Daniel Maloney, circus performer.
    • "The Santa Clara College monthly magazine, The Redwood, once referred to the Montgomery glider with naive accuracy as a dirigible-parachute."
    • Another source:   "Picture 1: April 29, 1905, saw the first public demonstration of winged flight above 1,000 feet. John Montgomery stands proudly beside “The Santa Clara” while Dan Maloney assumes the pilot’s position. At left are Justice W. G. Lorigan and Frank Hamilton. * "
