For the operation of a large pump-fed liquid rocket engine, the most important and critical working process is the starting process of the liquid rocket engine system. The success of starting is directly related to the success or failure of the launch of a space vehicle. During the starting process of a liquid rocket engine, very complex chemical and physical changes occur in the propellant components, and the engine system parameters change rapidly within a large range. Therefore, it is obviously important to conduct an in-depth simulation study on the starting process of a liquid rocket engine to reveal the pattern.

The success of starting is directly related to the success or failure of the launch of a space vehicle. During the starting process of a liquid rocket engine, very complex chemical and physical changes occur in the propellant components, and the engine system parameters change rapidly within a large range. Therefore, it is obviously important to conduct an in-depth simulation study on the starting process of a liquid rocket engine to reveal the pattern.
