Aiming at the problem of UAV fixed-point delivery. In this paper, the air resistance model in the aerodynamic model is combined with Newton's second law to construct an efficient solution to the ball projection problem at low speed. Firstly, the motion of the ball is decomposed into two directions: horizontal and vertical. By simplifying the model, the horizontal flight distance of the ball under three wind directions is obtained, and then the delivery distance of the aircraft is obtained. Secondly, considering the function of UAV to perform the blasting task, the aircraft used a certain Angle of dive, and subject to the distance constraints, followed by the dynamic model. Finally, through numerical iteration, the dive Angle of the aircraft under the wind direction and the straight-line distance between the position of the aircraft when it is launched and the target were obtained. Under the influence of different wind direction and wind speed, the aerodynamic model that can calculate the position and dive Angle of the UAV when it is launched at fixed point is obtained according to the direction and size of the influencing factors.
