Three Groups Of Rocket Engine Thrust Chamber Process Experimental Study And Numerical Simulation

In this paper,the characteristics of tripropellant rocket engine was studied in two different ways:experiment and simulation .As to the experimental study,a test system was designed firstly,which include propellant feed system,cooling system,controlling system and measure system. Secondly,a test engine was designed according to the experimental requirement. On this basis,experiments under different working conditions were done,and the results of them were analyzed,which showed the combustion efficiency and stability.As to the simulation,the inner flow field of thrust chamber was simulated. Here the thrust chamber was treated as a two-dimension problem. The simulation model involved injection,mixing and combustion of gaseous propellant.
