The Reverse Reconstruction and Finite Element Analysis of the UAV Impeller

As a key part of the power machine, unmanned aerial vehicle (UAV) impeller is widely used in aerospace field, and it plays a very important role in the national defense industry. Impeller in the work of higher speed, centrifugal force and aerodynamic force effect on the impeller at the same time, so that the impeller is easy to failure, a serious impact on the use of performance and life of the impeller. This paper mainly studies the method of using reverse engineering technology to reconstruct the impeller of the UAV, and carries on the finite element analysis software Ansys Workbench, which satisfies the requirement of precision and intensity of impeller model.
