    What if.....

    Just thinking....What if you built an airplane where the entire wing (or rather, each half) rotated for aileron and flap function...or either/or. Obviously, minor control input would produce major response, given the area of the control surface. Might be an interesting experiment with that plane you got tired of flying a long time ago.....I can imagine superfast rolls and loops.....Coments?

    RE: What if.....

    Sounds like a logical term.....have you ever heard of a plane built this way?

    RE: What if.....

    I believe I have heard of slope gliders built that way..I used to have a p38 slope glider that the entire wings past the pylons rotated.. instead of ailerons

    RE: What if.....

    What were some of the unique challenges in builting and flying this airplane? Do you think the technology is adaptable for powered flight?

    RE: What if.....

    interesting, i have seen something like this on discovery or history channels, in this planes case (RC at that, cant rember what show it was on but it talked about aerodynamics) the wings where not ridged, and kind of flowed with the thrust of the motor but where able to control the plane to, interesting system, the flowing wing tilt allowd the plane to not tip stall, it would fall to the ground with more control in a landing situation, odd but worked great.

    Infact the first plane built by the wright brothers used a wing twisting method of control. pulling and twisting the wood frame with strings, it actuallyed worked, and also f-16's and many other planes use this concept for the rear wings not the main ones, but the rear wing is the elevator.
    minor versions of this same concept in various parts of aviation, not to hard to picture them all togeather.
    I have thought about this my self but never realy got into the project, i have a million RC projects and it just never rose to the top of the list.
    Function over fashion, I dont do shelf queens!

    Me, too....but I have a bunch of older planes that might make fun test beds sometime

    It's an old thread, but this one was successful:

    RE: What if.....

    I've built something similar - see pics. The whole wing hinged together (variable incidence from +3 to about -3 deg), it still had ailerons and an all flying tailplane.

    Was capable of crazy manouvres with both the main wing and "all flying" tailplane pivoting, but very difficult to fly and eventually crashed it. Was interesting to built, fly and crash, but not something I'll do again. I had fast responses with above setup but it made it difficult to fly - think of this one: feed in positive wing incidendence while giving down stick (to dive), but the plane goes up like a helicopter instead of down, hadthe main wing stayed neutral - and vice versa..... Leaving the main wing in neutral incidence and the plane flies normally.

    Thereis a guy who built a JART slope soarer with independant pivoting wings http://sa-jarts.blogspot.com/search/label/Vicand best to contact him. These JART slopersare fast as hell, mine with normal ailerons clocked 170 km/hr. I doubt if you would be able to do superfast rolls with separate pivoting wings as it takes a lot of energy and servo power to move a big wing - you would have to use a fulcrum system which adds weight and uses energy. There are planes where the last end of the wing and wingtips rotate as you describe (circa 1930's) See attached black and white pic of a Westland-Hill Pterodactyl Mk. IA. I have only this pic, no info on it.Probably had adrenalineproducing wingtip stalls......Interesting concept though.......

    My experience is that continental drift sometimes causes the Earth to jump up and knock a plane out of the sky......

    RE: What if.....

    .
    Clancy Aviation had a Stagger Bee biplane with wingerons on the upper wing. In fact, I'm on a quest for one or even plans.
    I might not be very good, but I am fun to watch!

    RE: What if.....

    The two gliders that had wingerons that I flew were "Rotors" and "Turbos". Turbos were small light weight slope gliders with very thin wings, and FAST. They would roll faster than you could count. The rotor was a larger glider and also fast but not quite as manuverable. The biggest concern is keeping the pivot point slightly ahead of the center of liftthis keeps the load light and maintains stability. The easist way is to place the pivot point right on the CG, which convieniently is right were you want the main spar.
    The three most useless things to a pilot, the sky above you, the runway behind you, and the fuel on the ground.
