| Abstract: | The principle of torch igniter was introduced,and the torch igniters were classified based on the states of the oxidizers and the fuels.The structure characteristics of various igniters and thermal protection measures were analyzed.The torch igniter with the fuel of gas-oxygen/ethanol was designed for solid fuel ramjet ground tests.Thermal protection of the igniters was effectively reinforced by using the cooling method of regeneration ethanol and rotating fluid film.The torch igniters were successfully tested more than 30 times,with duration working time not less than 20 s. |
