Parameterised Analysis Model for a Quick Opening Valve in an Idealised Single Stage Gas Gun

Abstract

Gas gun systems generally consist of a high pressure gas reservoir connected by a quick opening valve to a projectile chamber. High acceleration of valve components make valve dynamics and stress analysis an essential component of gas gun design. A model has been created utilising various software packages that allow a user to easily model an idealised quick opening valve within a single stage gas gun. The model automatically performs dynamic analysis, fluid mechanic analysis, three dimensional model and mesh creation, and finite element analysis. The model requires only a set of variables describing the valve to operate. The model allows a user to analyse the effect of varying multiple parameters within a valve design quickly with only a basic knowledge of Matlab encoding.
