Abstract—Canister testing Chamber is one of the most critical components in Defence Organization. Unavailability of data and literature regarding Missile Canister, are considered to be one of the main contributors for the failure of manufacturing Canister Chambers in a local industry. Canister is used for carrying, storing and launching of missile. During storage and launching, the canister is subjected to an internal pressure of 45 kg/cm2 and external pressure of 9 kg/cm2. So it is very important to test the canister for these pressures. A Canister testing chamber is used to test the canister for both internal and external pressures. For testing the canister it’s both ends shall be closed by dummy dished ends. The test chamber will be used for testing of the integrated canister assembly for an external pressure of 9 kg/cm2 and internal pressure of 45 kg/cm2. As the testing chamber is subjected to these high pressures it shall be tested for any leakages through the hinged dished end. So the analysis of contact gap between this dished end and the shell of the chamber is to be done. To estimate the contact gap analysis a three-dimensional model of a canister testing chamber was made by finite element method using Uni Graphics.
