N2 - We propose a new type of rocket engine that uses the new compressive combustion principle based on supermulti-jets colliding with pulse, which may further improve the thermal efficiency of present rocket engines. In this research, we calculate the flow inside the combustion chamber of our new rocket engine by computation, based on the unsteady three-dimensional compressible Navier-Stokes equation, by using a method alike the C-CUP method. Computational results showed that auto-ignition occurred near the center of the chamber, and the pressure of the combustion chamber increased to 3-6 times the value of fuel tanks.
