In order to study the drag reduction effect of bottom cavity with side hole under high speed free stream, numerical simulation was carried out for the spin-formed body with bottom cavity and side hole. The effects of hole diameter, hole inclination angle, hole position and hole number on drag reduction are studied. The results show that the effect of hole diameter is nonlinear and there is an optimal solution. With the increase of hole diameter, and drag reduction increases first and then decreases. The smaller the hole inclination angle, the worse the drag reduction effect. The closer the hole is to the bottom of the cavity, the more favorable it is for the flow to adhere to the bottom, and the better the drag reduction effect. The circumferential position of the hole has little effect on the drag reduction effect. The larger the number of holes is, the larger the total hole area is, and the worse the drag reduction effect is. Since the flow into the hole is still supersonic, even if the flow direction is changed by the hole, it is still not sufficiently decelerated. Under the free stream of Mach number 6, the drag reduction effect of bottom cavity with side hole has certain limitations.
