Aerodynamics and aeroacoustics of flap side-edges [PDF]
An experimental and computational investigation was carried out to determine the aerodynamics and aeroacoustics of a flap side-edge. A porous side-edge treatment was applied to the flap side-edge in an attempt to reduce airframe noise. Measurements taken

Aerodynamic and aeroacoustic characteristics of a bionic morphing flap
Birds adapt to the changing flight conditions by performing intricate feather-movements to manipulate the airflow. The avian wings often undergo seamless transformations at the trailing-edge to achieve camber-reflexes for extended flight envelope.

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 ...
