In this paper, a new concept for low-drag, low-boom supersonic flight, by formation flying is proposed. This concept takes advantage of the shock wave and expansion wave interactions among the aircrafts in the fleet. Drag characteristics analysis is carried out on the concept to validate the effectiveness of supersonic formation flying as a means to reduce the wave drag of the fleet of supersonic aircrafts. Analysis results indicate promising drag reduction for supersonic formation flying, and insight on the physics of wave interactions in formation flying is obtained.
