Wing warping -- end of those gaps -- if nobody has said it already.



The Open class Jantar 2 in the late 70's had a version of this, with
camber changing flaps that have no hinge. The deflection is controlled
by deflection of the continuous upper wing surface...no upper surface
gaps.

You are right but you can't really compare these designs with Diana

2.
These early designs had very light wing loading comparing to the

massive
wing loading allowed in Diana 2.


E.G. Haase had that on his HKS 3 which he won the WGC in 1958
with. The production version SHK had ailerons though.. The
Wright brothers had that on their designs and patented it, so
Glenn Curtis came up with ailerons, which resulted in a huge
lawsuit.

I would love automatic flaps in a new bird. I would alos like different manufacturing to allow for lighter empty weight, helps if you fly a sustainer.




What was the deal with the automatic flaps on the Duckhawk? Was that ever made to work at all?


Pls. no automatic flaps yet !
If we agree : older flappers being not to today's standards( flaps not very effective);
All new to flaps pilots want automatic flaps.I was one of them. But...
Flaps have to be set before I enter specific airmass(rising, still or falling).
Same like my speed to fly has to be set before I enter specific air mass.
Chasing is counter productive.I do not try to follow my Speed To Fly computer. I have to predict and set.Then I could tap myself on the shoulder watching my STF computer if 10 sec ago I was wright.What ever it says , its history, and I should not try to change it.So its useless.
So I bet and try to cash in.
If I loose, I learn for next change and adjust my predictions.
I loose very little if I go in bit too fast conig.
I never predict perfect and every , even slow conig change costs me energy loss.
So usual winners like KS , bet on sinking airmasses and plows constant high speed 75-85 in Duo( even if there was little lift in between) to predicted good air mass under far away Cu or blue gaggle.
I can get same fast and little higher by betting on little lift in between clouds, wisps, blue thermalers and have correct speed and flaps ready ahead..
In cruising : more config changes = more loses, so if I'm not sure, I'm better off using plowing little too fast config.East coast 92kts in Arcus,

If I win the bet with myself, I do same predictions in next airmass.
With speed to fly and flaps setting , I have to be always ahead with predictions.
So "fly by wire" like Nixus : YES, "automatic flaps" : NOT YET,only for newbies, till we have a system predicting airmass at least 0.3 mile ahead like LIDAR.

I drive a car with a manual gearbox - and would never trade it for an automatic gearbox car. The same with my glider flaps....

All gliders should be made of wood.

I would like the canopy to be a HUD. Traffic marked by green yellow or red triangles depending on range and threat level. Vario, Air Mass (blue dot for Butterfly users), airspeed altitude, task info.

Oh and tappered wing pins

I'd settle for new-build Std Libelles with a revised, safety cockpit
structure.

Automatic changes to wing span is already being tested:

Was so tried of the hard deck discussion thought I would try a discussion of dreams. After seeing the vision of Elon Musk with his Falcon Heavy, I had to pinch myself. Those two boosters landing in sync..

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?


•if you want hyper elon musk futuristic, i've had some interesting ideas that seem totally and completely unfeasable, but then... future technology can surprise you. some of mine are purely imaginative, and not all that practical

First idea:
on-board super high powered de-humidifier. you could dump your ballast just before a climb, and then have the dehumidifier pull water out of the air and replenish water ballast for the next cruise during the climb.

or maybe that's too insanely fast to condense 30 gallons of water out of thin air. i don't know what am i, a scientist? but: suppose you could do it in a half hour rather than a few minutes. that would be perfect for longer record flights where its weak early or late in the day, or helping you get heavy again after dumping during a save.

•Second idea:
telescoping wings. wings that could telescope out to have a higher aspect ratio at the push of a button for long glides or weak weather, and telescope back in to make a lower span, higher wing loading when things are fast. really dynamic flights using many types of lift could benefit from the glider being able to shift gears too. i also thought about a glider that could have its wings sweepback a little sort of like an F-14. wonder how that would work with really fast flight to reduce drag, et cet.

•Smart flaps: automated flaps that make minor adjustments to keep optimal angle of attack

•also, these flaps:

http://www.flxsys.com/flexfoil/

This is something i envisioned for gliders and then i stumbled upon it and realized someone is already working on this! besides eliminating gap seals, drag from gap seals, and improving laminar flow in the aft part of an airfoil, it could be used to modify the airfoil shape for slow and fast flight.


•i always thought it would be cool if there was a glider with Fly-by wire, for very thin wings. the Nixus project is already doing this, so that's cool!
https://www.facebook.com/NixusProjec...3258876640913/

•FES where the prop sits flush in a garage on the fuselage like the more advanced bugwipers do.

•gliders with enough battery power (this one is more battery technology related, enter elon musk) to run a cockpit heater for winter, or high altitude flights flights.

If you crash glider, you will arrive at accident scene quarter inch after your glider structure. No safety cockpit will make fatal crashes survivable. If you want to improve safety rocket parachute is way to go. Or fly-by-wire control system that prevents pilot to do anything stupid.

I worked on an experimental "Water From Air" project a few years ago designed for arid climates (think Afghanistan.) The Mil-Spec called for something that could produce 500 gallons of potable water in 24 hours on 100 gallons of diesel (or jet fuel, JP4, Jet-A etc.) Other specs defined the climate as around 90 degrees F and less than 20% relative humidity.

The machine met the specs, and worked pretty well. It was also eight feet high, 16 feet long and eight feet wide. Weighed around 10,000 lbs. if I remember correctly. Ran on a CAT Diesel generator and made enough noise to wake the dead.
It was designed to fit through a C-130 rear cargo hatch and ramp. It did, with an inch or so of clearance.

So, that's 50 gallons in 2.4 hours on 10 gallons of fuel. Want to buy it? I can probably get you a deal, if the Army hasn't destroyed it yet.
