[0004] The development of a new type of liquid engine is the basic work for the development of aerospace transportation equipment system. The thrust-to-weight ratio is one of the most important overall indicators of the engine, which makes the calculation of engine mass a crucial link in the process of overall design and program determination. The rapid calculation of engine mass It can greatly simplify the workload in the overall demonstration and iterative optimization process of the newly developed engine, and improve the overall design efficiency. However, there is no simple, fast and efficient engine mass estimation method in the prior art
