The invention discloses a sharp vertex osculation tapered wave-rider with a controllable sweepback. A whole front edge of the wave-rider is a straight-line section; the angle of the sweepback at the front edge of the straight-line section is controllable at a design phase; a gas capturing curve is composed of one straight-line section and one section of circular arc; the circular arc is located on one side close to a symmetrical plane; and a circular center is an end point located on the symmetrical plane of a flowing capturing tube curve. According to the sharp vertex osculation tapered wave-rider, a stable separation vortex is generated on the upper surface of the front edge of a straight line with the controllable sweepback; and the aerodynamic performance of the upper surface is improved and the volume efficiency of an air vehicle is not sacrificed, so that the design of the upper surface is facilitated very well.
