Experimental Research On Simulation And Modeling Of Hypersonic Vehicle's Power System

The issue of the power system both axial symmetric hypersonic vehicle and lifting body hypersonic vehicle was studied particularly by means of both numerical simulation and hardware-in-the-loop simulation, estimating it's influence to flight experiment, provides criterion for the design and improvement of power system and control system.Simulation research was taken about the power system of axial symmetric hypersonic aircraft, estimating it's influence to flight experiment. Major problems of the power system were: interference of firing shock, breakdown of engine, deviation of firing time and deviation of design motor parameter.Simulation research was taken about the power system of lifting body hypersonic aircraft, estimating it's influence to flight experiment. Major problems of the power system were: working states change of engine, interference of firing shock and breakdown of engine.Establishing interpolation model of the engine thrust about incidence angle, sideslip angle, height and mach number of the axial symmetric hypersonic aircraft. Establishing surrogate model of the engine thrust about the angle of incidence of the lifting body hypersonic aircraft.
