A kind of small thrust engine

using gas oxygen and propane as the propellants

was designed in tune with the development of new generation small thrust engine that features non-toxicity

non-pollution

high performance and low cost.With platelet injectors

electrical spark ignition was implemented using the gap between different injectors.The film cooling injectors were used for cooling the body of the engine.An experimental system was designed and a series of experiments were conducted.The results show that the experimental system scheme is reasonable.The ignition of the engine is reliable and the combustion is stable

showing good effect of thermal protection.The experimental system and small thrust engine work well

indicating they are excellent fundamental platforms for the future investigation.
