The invention provides a design method of a sweepback controllable double-sweepback osculating cone full waverider aircraft, which comprises the following steps of: designing a central body bus of a reference flow field, and solving position coordinates and flow parameters of each point in a flow field area and a shock wave molded line by applying a characteristic line theory; designing projection molded lines of the front edge and the air inlet lip of the aircraft on the horizontal plane, and defining the sweepback and the size of the aircraft; designing a shock wave outlet die line of the aircraft, and determining shock wave shapes and flow field parameters on each osculating plane and an included angle between the osculating plane and a vertical plane; the shape and position coordinates of the aircraft three-dimensional front edge molded line and the air inlet lip molded line are solved, and the position coordinates of the intersection points of the osculating planes and the aircraft front edge molded line and the air inlet lip molded line are obtained; a reference flow field in each osculating plane is solved, and streamlines on the molded surfaces of all the parts of the corresponding aircraft in the osculating planes are obtained through streamline tracking; and smoothly connecting the streamlines to obtain the basic configuration of the aircraft. The performance of the aircraft is guaranteed on the basis that the design freedom degree is improved.
