Abstract:
Since it is very expensive to execute the test of the full-scale hybrid rocket engine, the scale hybrid rocket engine is usually adopted for the test. In order to improve the cost-efficiency ratio of the test, the similarity analysis is carried out for the hybrid rocket engine to determine the conditions under which a laboratory scale hybrid rocket engine should be tested to simulate the firing of a full-scale system and to define the relevant scaling rules for hybrid propulsion system. Similarity requirements are given and analyzed in consideration of liquid oxidizer. The relative significance of the requirements is evaluated, and are established. The performance of hybrid rocket engine is predicted according to the
