Abstract: The influence of imaginary component of propellant response function on the oscillating combustion frequency of rocket engine is concisely analysed by a real example.It is the main reason to cause the difference between predicted frequency and the measured.

Key words: Oscillating burning;Combustion property of propellant;Rocket engine
