Abstract


Technology advancements in Base-bleed and Rocket Combined Improved Range Projectile have led to demanding requirements for the working performance of solid propellant rocket engine. The research on the internal flow characteristics at high-speed revolution state is of great theoretical and engineering value. This is because of it can have a directly affection to the engine working performance.A two-dimensional CFD simulation of internal flow at high-speed revolution state was developed with FLUENT in this paper. The diagrams of Mach number contours, pressure-Mach number distribution along axis and pressure-thrust to revolution were derived at varying speeds. The influences of high-speed revolution on pressure, on thrust and on flow have been analyzed. We can get experiential functions of maximum thrust to revolution and of maximum pressure to revolution with data-fit method. These conclusions can present some references to the rocket design.
