Supersonic airfoil3/16/2023 ![]() ![]() Wave drag is an inherent component of drag induced at supersonic and transonic flows due to the creation of expansion waves when supersonic air flow hits the inclined airfoil leading edge. The Concorde: the first supersonic passenger aircraft Wave drag causes an abrupt pressure drop over the wing surfaces, resulting in instantaneous loss of lift and hence, is very dangerous. It should also be noted that a new type of drag apart from skin friction and pressure drag known as the wave drag appears, due to the compressibility of the air and the presence of the high energy shock waves around the aircraft.
