HELICOPTER RETREATING BLADE STALL CONTROL USING SELF-SUPPLYING AIR JET VORTEX
Inst. of Aviation, Warsaw, Poland
Keywords: applied aerodynamics, flow control, rotorcraft
The work presents the results of wind tunnel tests of using self-supplying air jet vortex generators to delay dynamic stall. The tests were performed on NACA0012 airfoil at condition simulating flow around helicopter blade airfoil. Results shows that usage of these generators causes a small lift and moment stall delay.
