The fan blades in the subsonic intake of jet aero engines have an important impact on the efficiency of the aircraft, whether the engine is working normally, and the size of the thrust. In view of the current problems in the design of jet aero engine blades, this paper carries out the design of the shape and number of engine blades. First of all, some of the current problems with heat dissipation in the engine blades are analyzed. Secondly, based on how to improve the cooling effect of the air intake fan blade of the jet aircraft engine, the design of the fan blade in the engine air intake was carried out. Finally, the 3D modeling software has been used to improve the engine air intake fan blades. The design results show that the desired effect is achieved for increasing the number of blades of the fan blade and improving its shape, and the cooling effect on the engine is improved.
