Overview

Regarding the mechanical response of the electromechanical system during the penetration of an unpowered aircraft into water, dynamic simulation software was used to numerically simulate the mechanical characteristics of the electromechanical system during the penetration of a certain unpowered aircraft into water at different landing speeds. A comparative analysis was conducted on the overload of the electromechanical system when different buffering materials were used between the electromechanical system and the aircraft. The numerical simulation results showed that when the aircraft penetrated water at different speeds and an angle of 90°, the overload value was small, and the buffering effect of the buffering material on the electromechanical system was not significant. However, due to the presence of the front wing and tail wing, the overload value of the electromechanical system showed three peaks, especially when the speed was high. After the tail wing is damaged, the overload peak of the electromechanical system might not be synchronized with the peak of the aircraft, which may have a certain impact on whether the electromechanical system can work reliably. The results of the analysis can provide some references for the design of the reliable operation of the electromechanical system of unpowered aircraft.
