Can Dihedral wing Angle negate the need for Ailerons
For the unknown of physics. I’m not a pilot/engineer, but designed a handful of UAS for the Army/DoD which is thought to be impossible because infantrymen are supposed to be dumb grunts, but got the attention of the Army/ few aerospace companies, etc, but what I learned is that engineers think...- Dav-h12

Can Dihedral wing Angle negate the need for Ailerons
The Bonney Gull had ailerons, but the rear elevator seemed to be one gull/dove tail shape. Most of us have seen birds and they roll their tail feathers on the longitudinal axis; flare their tail feathers out wide and draw their tail feathers close in. I suppose the interest of Bonney was...- Dav-h12

Can Dihedral wing Angle negate the need for Ailerons
The post was due to my curiosity watching birds (change dihedral across their wings) and seen one ultralight some years ago with no ailerons and some pilots were real up nosed about it while other pilots thought it to be interesting. The bird photo referenced inflight dihedral changes and...- Dav-h12

Can Dihedral wing Angle negate the need for Ailerons
Just a reference of dihedral angle…that birds can change at will.- Dav-h12

Can Dihedral wing Angle negate the need for Ailerons
Seen a number of opinions, all pilots, on this subject: If a wing has sufficient dihedral angle, ailerons are not needed. There have been more than a couple pilots in aviation history that have died from their designs modeled after birds(biomimetics). Speculative opinion: birds have exceptional...- Dav-h12

Morphing airframe & Human interface rotor control
I originally started this thread in post in 2010 etc. I’ve been out of the net for several years. Dealt with a lot of stuff, retired from the Army 2016 and dealing with the VA norw. After the small scale flew ok in 2012(bit under powered), I did a few UAS designs for some DOD folks. Since...- Dav-h12
