The aerodynamic configuration of supersonic aircraft has an important effect on the intensity of sonic boom. Low sonic boom supersonic aircraft aerodynamic configurations have been researched extensively. Based on the systematic investigation of foreign sonic boom suppression technologies, this paper describes five aerodynamic methods proposed by foreign researchers for reducing sonic boom of supersonic aircraft, and sums up relevant lessons and experience. Four main aerodynamic configuration types of low boom supersonic aircraft are summarized and analyzed. According to the aerodynamic configurations of new supersonic aircraft, it is concluded that the delta wing is the mainstream aerodynamic configuration of the next generation environmentally friendly aircraft. An outlook of the aerodynamic configurations of low boom supersonic aircraft is given in the last part. .
