Abstract:
In this paper, the heat transfer condition of a FSO（Face Shut Off） pintle injector engine head is analyzed and modeled with numerical method. The instantaneous temperature states of the propellant in the engine head during working and shut-off states are computed. The results show that the rise amplitude of the propellant temperature is small when the engine is at work, and the propellant temperature rises less than 200℃ after the engine is shut-off. The conclusions above show that the propellant in the engine head is at a safe temperature range.
