PROBLEM TO BE SOLVED: To provide a rocket engine analysis device capable of improving the analysis precision of the state quantity of fluid in a pipe passage. SOLUTION: This rocket engine analysis device for analyzing the state quantity of fluid flowing in the pipe passage of a rocket engine has an input means 62 for inputting a pressure value and the enthalpy of the fluid in the pipe passage, phase state discrimination means 64, 66, 74, 76 and 78 for discriminating whether the fluid in the pipe passage is in a one phase state or a two phase state based on the inputted pressure value, and calculation means 64, 66 and 74 for calculating a pressure value and enthalpy after a predetermined period of time elapse using a one phase state calculation expression 80 when it is discriminated that the fluid in the pipe passage is in the one phase state and a two phase state calculation expression 82 when it is discriminated that the fluid in the pipe passage is in the two phase state.
