Possibly because the Wright Brothers held a patent on flight control surfaces that was so broad it covered anything from wing twist to ailerons, even though ailerons had already appeared earlier in European designs. It took a world war for that patent to be forcefully lapsed "for the good of humanity", i.e. , to allow other people to build better weapons.

Nope, don't think so. He was using classic ailerons which was one of the big disputes concerning the Wrights. I think this inventor simply thought he had invented something better as a pitch control.

When I did the drag control thing - - (which I abandoned ) it was obvious that how the drag is arranged on a aircraft can change trim very easily.
The model would loop nicely , simply deploying the split rudders .
This is the kind of stuff one can try on a model -and see what REALLY happens

Thanks Thomas!

I have that news reel on VHS tape somewhere, so that is definitely where I saw it too. Nice to see it fly.

It is a creative way to reduce the performance of an airplane, for no particular gain.

Unfortunately, I don't think that kind of creativity will ever go out of style...

Those pictures do not support your point, as the creativity shown in them WAS done for particular gains, unlike the odd experimental wing under discussion....

It is an odd world where destroying people and infrastructure is routinely thought of as a gain...

I tried to find some pictures that highlighted the canted pylons on the Super Hornet, which fall squarely in the category of a "creative way to reduce the performance of an airplane, for no particular gain." They may have been canted for a reason, but not for particular gain.

I think you know less about aerodynamics than you think you do.

cant both in and fer shere - you get an up pitch.
given the size n position - probably quite effective

The F22 introduced the use of rudders as airbrakes. Yes, they do change the pitch trim as well, but that can be compensated with the elevons. It has the advantage of reducing the increase in radar signature that would be caused by using the airbrake. That's also the reason why the B2 uses split elevons as rudders. Adding a vertical surface would be easy, but it would increase the radar cross section massively.
