导弹发射出筒过程中喷出的燃气一般包含大量的可燃高温气体，一般这些可燃气体直接排放到了环境当中。如果使这些可燃气体再次燃烧则可以释放十分可观的能量，这些能量足以弥补水下发射时发射深度的增加而需要的额外能量。研究了同心筒内二次燃烧过程，建立了导弹在同心筒内运动的集中参数模型。仿真计算了不同水深发射时导弹筒内运动及出筒速度，计算结果表明同心筒内燃气二次燃烧有利于减小导弹水下不同深度发射时的速度散布。

A lot of burnable gas is included in flow-gas produced by a launched missile moving in the launch canister. Generally, that kind of gas is useless and is expelled to the environment. Actually, if the gas can be burned again, a mass of additional energy can be gained, which can make the missile move more quickly when launching underwater. The method of calculating burning energy and the process of post-combustion are studied in this paper. Then, the process of missile moving in launch canister and the missile’s velocity with post-combustion are analyzed using zero-dimensional modeling. In comparison with conventional launching, the velocity dispersing of missile can be reduced.
