| Abstract: | Multi pipe synchronous ignition technique is one of the key techniques of aerospike engine. Design and experiments of a gas oxygen/alcohol multi pipe igniter were introduced. The key factors influencing multi pipe ignition were studied, which include propellants mixture ratio, time of igniting, material and geometrical size of the pipe, methods used to cool the igniter, and oxygen supply combustion. In addition, ignition methods at high altitude were also investigated. On the above basis, parameters of the igniter were determined, multi pipe synchronous ignition was realized. |
