The Supersonic Double Wedge airfoil has poor performance at subsonic speed regime due to sharp edges stall. For this purpose, a theoretical and experimental study was undertaken to improve the performance characteristics of the supersonic double wedge airfoil at low speed by using passive-active flow controlling methods. The proposed passive method was a shape modification through changing the sharp leading edge and mid-section upper and lower apex to smooth curved control segment which activated during the subsonic flight regime. The airfoil returns to its standard shape at supersonic speed b...
