SYSTEM FOR EMERGENCY PROTECTION OF LIQUID ROCKET ENGINE

摘要

A system for emergency protection of a liquid rocket engine is provided to perform emergency protection operation by transmitting last emergency stop command in case the information processed in two or more signal processing parts are included under the emergency stop condition. A system for emergency protection of a liquid rocket engine comprises: a plurality of signal sensing parts(110) sensing the sensing information including the revolution per minute, vibration, pressure, temperature, and optical information of the liquid rocket engine; a plurality of signal processing parts(120) processing sensing information as a digital signal and comparing the processed sensing information with the critical condition stored in advance; an emergency stop control part(130) generating emergency stop signals stopping the liquid rocket engine in case the sensing information transmitted from two or more signal processing parts is deviated from the critical condition stored in advance at the same time; and a liquid rocket controller(140) controlling the drive of the liquid rocket engine and stopping the liquid rocket engine in an emergency according to the emergency stop signals.
