Design and Analysis of Pyro Based Transportation Lock and Release Mechanism for Smaller Flight Vehicle

Abstract

Pyro based mechanisms are generally used in flight vehicles for various purposes. Here, a pyro based transportation lock and release mechanism has been designed to lock (arrest the movement of) the flight vehicle to the container tube during transportation and handling (in the captive mode) and to release the flight vehicle before the firing. In this paper, Classical Design and Finite Element Analysis of the individual components (piston, pyro body, flange and shear pin) and the assembly of the transportation lock and release mechanism are presented. This mechanism has been fabricated, ground tested and field tested successfully in flight trials.
