Why has that technology not been used in other gliders?

I think, the most original thought was Diana 2 sparless wing, that allowed the highest wing loading range of any sailplane.


Damage intolerant structure. Difficult to repair if damaged.

Foka 4 and SH-1 also have "Sparless" Wings.

High wings like the JS-3 were pretty standard up through the Ka-6

What's old is new again

Plaster all surfaces of a 1-26 with solar panels and equip with electric sustainer. Give it to Daniel Sazhin and see how long he can stay aloft...

And telescoping wings were done in the 70's (Lookup FS-29), as well as the extending TE to change area and camber (FK3 and Sigma)http://www.betsybyars.com/guy/soarin.../70-sigma.html

Mechanics on both of them created quite a workload for the pilot.

By the time the configuration change was complete, the glider had sailed far beyond the thermal.

What are some of the innovative, new technology, original thought, scifi dreams, would you like to see in a brand new glider design? Let your inter Elon Musk flow.

We have seen the New Ventus, the JS-3 (very innovative), Dianna 3. So far the South Africans have shown the most original thought.

If you were to design a glider what are your dreams?

18/21 or 15/18 meters

Sustainer, jet, electric, two stroke?

Light weight: I would love to be able to get to 7.5 pounds with a 220 lb pilot+chute and up to 12ish pounds wet. This might take new manufacturing methods and materials. Perhaps pre-preg, vacuum bagging...?

Pedestal mounted wing?


Pedestal -- Look at the Lo-150 (& Lo-100 aerobatic) sailplane. The fuselage at the rear spar is so narrow, one wing connects to the fuselage and the second connects to a fitting on the first wing. Again, like Tony said, not a new concept...

Thanks for sharing those Sigma details! Fascinating.

Time to start asking for biodegradable gliders. Gelcoat is a major step in that direction but we have a long way to go.

If you are looking back, you may as well look at the German gliders
of the 1930's. Most had high wings, and some were pedestal
mounted.

Also, for camber changing flaps, IIRC, the SB-11 which Reichman
used to win the 1978 15m WGC had them too.

Biodegradable gliders? Uhh- I guess we could go back to wood.

Regarding the Std Austria SH1, I question the "sparless" statement;
it had a rather massive wooden spar with steel caps at the root,
coupled by large pins, driven into place by captive RH and LH screws.
It was close to best 15m ship at the time, thanks to the new Eppler 266
airfoil and the use of fibreglass over the playwood wing skin; it would outclimb the vaunted Sisu and outrun the K6 E.
I flew one to 4th place in the 1965 US Nats in Adrian.

cheers

John Firth Ottawa.
