On the basis of the analyzing the whole launching process, the mathematics model of the inner ballistic is deduced. Computer procedure is complied through Visual C++ development tools, which simulate the launching process and obtain the main performance curve of inner ballistic trajectory. Mathematics model is also modified through the experimentation data. At the same time, the experiment has proved that the new launching technique has the capability of raising the muzzle velocity.
