Analysis of Power Parameter in Trajectory Controlling Engine Based on Proportional Navigation

Aiming at the scenario of the 3-axes stable proportional navigation,control and guide using in space-interceptors,with the analysis of three traditional operate modes of the fluid propulsion engine known as stable thrust,variant thrust and impulse thrust,the operate modes of the space-interceptor are analyzed.Some useful references on choosing fluid propulsion engine type and macro-technology of the interceptor are also given in the end.
