Experimental research of helium resonance heating surface igniter

Gas dynamic resonance igniter, which creates the ignition resource of high temperature and high energy, is applied to ignite non-hypergolic propellants. Helium resonance heating surface igniter with light and simple structure is powerful and reliable. It can be concluded from experiments that the helium resonance heating surface igniter has good resonance performance even when gas temperature or inlet pressure has large variance, which leads to more application of helium resonance heating surface igniter. The kerosene-oxygen and hydrogen-oxygen igniters are able to multiple ignite and produce ignition torch successfully. Since the flux of propellants and the temperature of ignition torch can be varied in a wide range, two torch igniters satisfy various ignition requirements of liquid rocket engines. The present research shows that the helium resonance heating surface igniter and the keroseneoxygen and hydrogen-oxygen igniters characterized with advantages of simple structure, high reliability, and non-poison, etc., are prospective to be applied for multiple ignition of liquid rocket engine.
