Kinematic Design and Analysis of Munition Ejector Release Unit

Abstract

In this study; design, analysis and optimizations will be done to open the hanger handles at fixed intervals on the ammunition attached to a release mechanism. The hook arms are held by the mechanism and release the hook arms at equal angles and at equal speeds when the last opening command is given. Munitions which have a 30-inch lug distance, can be used in this system. The boundary conditions of this rigid mechanism are determined. The design and analysis of this mechanism is done analytically and numerically. After various designs and analyzes, dimensions are achieved suitable and optimized for the angle ranges that rigid mechanism works. Through this design, kinematic of the hooks and parts are obtained. The mechanism that performs desired movement are analyzed with the finite element method; the kinematic movement data of the created 3D design is verified to confirm.
