Study on theory and test of a new type' concentric canister with jet flow' vertical launcher

According to theory analysis and validate test on the process of launching missile with concentric canister, it testifies that heat environment is the most important problem that exists in concentric canister launch mode. In this paper, we bring forward the concept of ejecting concentric canister with creativity; it offers a new and credible technique approach that downright solve the matter of heat environment around missile when launching missile with concentric canister. Ones more, by the methods of resolving stationary/non-stationary, three-dimension Navier-stokes equation, it testifies in theory that ejecting concentric canister may lower gas temperature around the missile in launching greatly. At the same time, it has testified the existence of ejecting concentric canister phenomenal according to test.
