To obtain an electric-powered propulsion system meeting the engineering requirement of small loitering munition, the vortex theory and the first-order motor model were used to establish the efficiency calculation model of the electric-powered propulsion system. The parameters of the propeller and motor were quickly designed by taking the efficiency of the electric-powered propulsion system at cruise as the objective, and the thrust and maximum counter torque in climb as constraints. According to the indicators of motor and propeller, the motor dynamometer test was carried out and the motor selection was completed, the propeller parameters were optimally designed in detail by using the Kriging agent model, and complete aerodynamic parameters were calculated. The wind tunnel test was carried out for the electric-powered propulsion system of the small loitering munition. The results showed that the deviation between the theoretical calculation and the test of propeller was within 85%, the deviation between the design and test results for the efficiency of the electric-powered propulsion system at cruise was within 27%, showing that the design method of the electric-powered propulsion system is reasonable and effective, thus providing a reference for the design of small loitering munition.
