Nonharmonic Control of the Blade-Vortex Interaction Noise of Electrically Controlled Rotor

open access: yesInternational Journal of Aerospace Engineering, 2022
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 ...

Active Flow Control for Trailing Edge Flap Separation [PDF]

open access: yes2018 AIAA Aerospace Sciences Meeting, 2018
Active flow control (AFC) in the form of sweeping jet (SWJ) excitation and discrete steady jet excitation is used to control the flow separation on an NACA 0015 semispan wing with a deflected, simple-hinged, trailing edge flap. This geometry has been the focus of several recent publications that investigated methods to improve the efficiency of ...

A general model for trailing edge serrations simulation on wind turbine airfoils

open access: yesTheoretical and Applied Mechanics Letters, 2021
Trailing edge serrations (TESs) are capable of noticeably suppressing the turbulent trailing edge noise induced by rotating wind turbine blades and become an integral part of a blade.

Influence of Gurney Flap and Leading-Edge/Trailing-Edge Flaps on the Stall Characteristics and Aeroacoustic Performance of Airfoils

open access: yesFluids
In aerospace, flow control techniques have improved the separation flow characteristics around airfoils by various means. In this paper, the delayed detached eddy simulation (DDES) technique is used to simulate the detailed flow field around the NACA0021
