Regenerative Liquid Propellant Auxiliary Chamber Emission Technology

According to the working principle and process of regenerative injection of the regenerative liquid propellant auxiliary chamber gun, this thesis analysis the process of regenerative injection cycle and puts forward the structure of the auxiliary chamber. 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. Then, in this paper, the main effects for performance of inner ballistic trajectory, which is affected on by the change of some mainly structure parameter of the auxiliary chamber are simulated and discussed. According to analysis of a series of curves that gained by numerical simulation, the conclusion how to obtain the best performance of the inner ballistic trajectory and optimize the structure design is educed.At last, the existing problems of this new technology at present are discussed and some requires and proposes which are needed to development for future are put forward.
