The invention provides an aerodynamic/structural/sonic boom three-discipline rapid optimization design method for a supersonic civil aircraft. The method comprises the following steps: determining an aerodynamic design variable and a structural design variable; determining that the sonic boom design variable is the same as the pneumatic design variable; establishing an incidence relation between the coordinates of the aerodynamic configuration surface grid points and the structural design variables; and establishing a pneumatic/structure/acoustic explosion multidisciplinary optimization mathematical model. Compared with a traditional single-subject design, the method has the advantages that the three subjects of pneumatic/structure/acoustic explosion are extracted for comprehensive design, and the overall performance of the concept scheme of the design is coordinated; and 2, the aerodynamic shape variable is associated with the structure shape variable through the grid points on the surface of the aircraft, so that the redundancy of the design variable is reduced, and the optimization efficiency can be improved. And 3, a multidisciplinary rapid analysis method is adopted, so that the performance of three disciplines of pneumatic/structure/acoustic explosion can be comprehensively improved within a plurality of hours, and the top-speed design of the concept scheme of the supersonic civil aircraft is realized.
