The use of computational fluid dynamics (CFD) to optimize the aerodynamic shape of rotor
airfoils with the aim of suppressing dynamic stall is computationally expensive and …

Airfoil optimization is the key to improving the aerodynamic performance of a rotor. However,
conventional optimization approaches cannot modify the airfoil shape intelligently in the way …

A co-flow jet (CFJ), an active flow control method combining blowing and suction control,
can effectively suppress the stall of airfoils. However, the streamwise jet channel along the …

In this study, micro jets were applied to actively controlling the flow of the international
standard ducted propeller model. The detached-eddy simulation (DES) method with the …

Abstract The Co-flow Jet (CFJ) technology holds significant promise for enhancing
aerodynamic efficiency and furthering decarbonization in the evolving landscape of air …

In this study, a model was created numerically to study the effect of active flow control on
helicopter blade to improve the retreating blade stall. Active flow control is applied to …

A flap can be used to control wing camber and as a high‐lift device. A convex corner is a
simplified model of the upper surface of a flap. At transonic speeds, shock‐induced …

直升机在大载荷高速前飞时, 旋翼桨叶桨距变化较大, 易发生动态失速; 后行桨叶内段旋转线速度
