The invention discloses an osculating cone waverider with curve head and controllable sweepback angle. The whole front edge of the waverider is a straight line section, and the sweepback angle of the front edge of the straight line section is controllable in the design stage; a gas capture curve consists of a straight line section and a circular curve, the circular curve is positioned at one side close to the symmetrical surface, the center of circle is positioned on the symmetrical surface, is higher than a flow capture tube curve and is positioned at the end point of the symmetrical surface, and the distance between the center of circle and the end point is the circle center deviation distance. According to the osculating cone waverider, the front edge of the controllable straight line with controllable sweepback angle generates stable separating vortex, the aerodynamic performance of the upper surface is improved, but the volume efficiency of an aircraft is not sacrificed, so that the design of the upper surface is facilitated.
