Journal ArticleDOI
Aerodynamic optimization and mechanism design of flexible variable camber trailing-edge flap
TL;DR: In this article, a flexible variable camber trailing-edge flap is introduced, capable of changing its shape smoothly from 50% flap chord to the rear of the flap, which can improve flight efficiency during takeoff, cruise and landing states.
Journal ArticleDOI
Transonic buffet control research with two types of shock control bump based on RAE2822 airfoil
TL;DR: In this paper, two types of shock control bump (SCB) are designed according to the two different mechanisms: backward and forward SCB, and the results show that the downstream SCB can better the buffet performance under a wide range of freestream Mach number and the steady aerodynamic characteristic is similar to that of RAE2822 airfoil.
Journal ArticleDOI
Flow characteristics around airfoils near transonic buffet onset conditions
TL;DR: In this paper, three typical airfoils: the supercritical OAT15A, the high-speed symmetrical NACA64A010, and the thin, transonic/supersonic NACA 64A204 are selected as the research objects.
Journal ArticleDOI
Aerodynamic Characteristics of a Ducted Fan Hovering and Transition in Ground Effect
TL;DR: In this paper, the aerodynamic characteristics of a ducted fan hovering and transitioning in the ground effect are studied using numerical simulations in a vertical takeoff and landing vehicle, and the flow fields are obtained by solving Reynolds Averaged Navier-Stokes equations with the Multiple Reference Frame approach.
