Nonharmonic Control of the Blade-Vortex Interaction Noise of Electrically Controlled Rotor
Electrically controlled rotor, also known as swashplateless rotor, represents an active rotor system that, due to the use of a trailing edge flap system instead of a swashplate, not only enables primary control but also conveniently reduces the blade ...

Numerical analysis of stagger Supersonic biplane at off-design condition with trailing edge flap [PDF]
Supersonic biplanes can achieve low-boom and low-drag supersonic flights. In the present study, aerodynamic analysis of a two-dimensional stagger Bussmann biplane (staggered upper element by 0.5c) at zero degrees angle of attack with trailing edge flap ...
