Reliability Evaluation of a Certain Missile's Telescopic Wing Deployment

Abstract

Compared with fixed wing, the telescopic wing can effectively reduce the space of aircraft missile bay.The reliability reduction becomes a problem that cannot be ignored due to the existence of the mechanism of the telescopic wing.In order to explore the reliability of the new mechanism, the positioning reliability of a certain type of telescopic wing deployment mechanism is calculated from a theoretical perspective, Adams is used to simulate the deployment process of the telescopic wing, and the Adams/Insight module is combined to calculate the clamping reliability under the friction force.The reasons for the clamping failure of the telescopic wing are analyzed.The results show that the presence of foreign matter can significantly reduce the positioning reliability of the telescopic wing, the suitable increase of preload of upper and lower wing springs can effectively reduce the clamping failure of telescopic wing mechanism, and the additional torque generated by the upper and lower wing springs at the center of mass of the upper wing can reduce the clamping failure of telescopic wing.
