Abstract:
The kerosene filling system is an important part of test-bed for large thrust rocket dynamical system. It supplies kerosene continuously, reliably and accurately to the rocket tank. The selection principle of centrifugal pump is determined according to the system requirement of large flow and pipeline characteristic curve. Through the comparison among three methods of throttle control, bypass regulation and frequency control, it is pointed out that the strong points and feasibility of the frequency control method are the most. The test of several dynamical systems has been accomplished by variable frequency pump, in which every kerosene filling state is normal, filling flow is stable, and the results can satisfy the requirements of the ground test system. The variable frequency pump possesses big flow span, high control accuracy, flexible flow switch and fast modulating response. It is an effective way to ensure the kerosene filling system is secure, steady and
