In the process of accelerating a certain UAV to take off, the elevation angle of the launcher needs to be adjusted according to the aerodynamic characteristics of the UAV. The aerodynamic characteristics of the UAV affect the kinetic analysis of the launching process, and in order to ensure that the UAV can take off smoothly and at a predetermined speed, it is necessary to find the optimal launching angle of the launcher to provide data support for the launching kinetic simulation. In this paper, a simple aerodynamic estimation of a certain UAV is carried out based on CFD software, and the amount of calculation is reduced by simplifying the model and the calculation process, and the aerodynamic performance parameters of the UAV are finally obtained through simulation.
