Twenty blades truss-held ... all autorotating for hang glider?
Dropping the kite line June 1928 cover of Popular Mechanics   ... then some glider notes on page 888 for Motorless Ships of the Air           |     towrope, "flivver" , roots of aerotow Espenlaub

Clip from the June1928 issue of Popular Mechanics magazine (page 891)  where "Breslau students" are noted as having built the shown glider. Twenty years earlier in 1908, a gliding club in Breslau achieved a hang glider that was most simple in the pilot area: pilot hung behind cable-stayed triangle control frame (TCF) or A-frame for weight-shift control; such arrangement was used in various ways during the following decades by Spratt, by Igor Bensen, and eventually by Burns in Australia and then others like John Dickenson in the 1960s-70s hang gliding renaissance.  The late Dave Kilbourne credited on his plan for a hang glider that went through Low & Slow to 23 countries to spark a hang glider manufacturing explosion, appropriately NASA for strong guide on the framed flexible wing known mostly as the framed Rogallo wing, though framed flexible wings were known since early 1800s. Full research on Breslau would be neat.          Anyone on Breslau?                        ~~JpF

Pilot designer of glider is shown: Igor Bensen in early 1950s shown tensionally hung behind triangle control frame (or A-frame, though rounded) that he pressed to change the relative position of his mass with respect to the glider's wing.  The early at-least-by 1908 A-frame for glider cable-stayed was sometimes strut stayed (Espenlaub), elongated but cable-stayed (Spratt), morphed for landing gear as pilot would move up with aero controls, strut-stayed by Barry Hill Palmer, cable-stayed by Burns, etc. the oscillation of cable-stayed and strut stayed would occur even to the present.  Also see the morphed TCF as undercarriage for nearly every aircraft ...with wheels on the two corners frequently.

Concept for Torrey Pines Gliderport offshore: 
Have an anchored barge that has a solar-energy collection/conversion surface; have that same barge be a wave-energy conversion device. Have at the barge an energy storage battery to store much of the gained energy. Then have the barge as a landing area for hang gliders. The gliders will soar and then land out on the barge. Use some of the gained energy to charge the electric boat that will ferry the hang gliders back to land. Or use the energy to recharge the batteries on electric-powered ultralight tug that ferries the hang gliders back to altitude for another soaring session or top landing. Or use some of the stored energy to recharge hang-glider e-powered harnesses. Avoid using the official gliderport takeoff; fly into the slope airspace with e-powered harnesses; shut off power and soar. Land at the barge clubhouse.  The barge could be a clubhouse for hang gliders.    What are the coast-guard rules for such matters?

Celebration event announced by Chris Bolfing:

In recognition of the birth of modern hang gliding 40 years ago at the Lilienthal Meet of 1971, I am organizing a fly-in at Torrey Pines on the weekend of April 2-3rd, 2011. A third day in the local mountains will be added on Monday, April 4th with sufficient interest.

Torrey Pines is a ridge soaring site located in beautiful San Diego, California, USA. It is famous for early sailplane flying, hang gliding, paragliding, and remote control gliders. The best season is typically in the spring with west winds off the Pacific Ocean and beach thermals. Grassy setup area and top landing make this an ideal site for demos and display.

Several manufacturers have confirmed that they will be participating with glider demos. So far there will be gliders from Moyes, Icaro, UP, and Northwing.

A number of vintage gliders will be on display and if you have a cool one in the rafters, bring it out.

So if you are thinking of a new glider this year, or are a vintage pilot, wear your oldest hang gliding t-shirt and come on out. New pilots and 2nd generation pilots welcome too.
