摘要：

Through combining steady state working model and thermodynamic calculation model of liquid rocket engine, numerical simulation analysis of turbo pump-fed liquid rocket engine where the unsymmetrical dimethylhydrazine (UDMH) is partially oxidized is presented with the methods of least-square optimization and iterative computation. The result shows that as the content of dimethylamine, unsymmetrical dimethylhydrazone and water increasing in UDMH, the mixture ratio has a slight elevation while the engine thrust, chamber pressure and chamber temperature decreases obviously. Compared with analyzing energy features of propellant only, the effect of metamorphic propellant on liquid rocket engine can be better reflected under the complex regulatory mechanism of rocket engine system with such a method. © 2016, Editorial Dept. of JA.
