Invalid-storage model of a launch canister during maneuver environments

The invalid-storage model of missile launch canisters in maneuver environment was studied. It pointed out that, strong sunshine radioactive and high humidity air are the main reasons which result the leakage of a missile canister. The time-temperature and time-pressure variation models were established and the variation processes were simulated, simulation results are similar to the real world changing process inside in canister during missile's maneuver. Some constructive and practical advices are given out witch could improve the environment adaptation ability of launch canisters.
