摘要：
Improve the efficiency of propulsion system is an effective mean to archive flight performance improvement of electric-powered tilt-rotor. In this paper, the motor is constructed by combining the motor equivalent circuit model and the positive polynomial loss model. The proprotor is modeled by Goldstein vortex theory and the validity is verified. Based on this, aimed at an effective optimization goal, a comprehensive optimization method for the propulsion system is proposed using optimization algorithm. Then the optimization of the propulsion system was carried out and an effective optimization program was obtained for a small electric-powered tilt quad rotor. The research results show that this optimization method can effectively solve the problem of motor and proprotor matching. By optimizing the design of the propulsion system, the power demand can be effectively reduced and the flight performance can be improved. © 2019, Springer Nature Singapore Pte Ltd.
