Auxiliary starting device of bomb turbojet engine in ground joint debugging test

The utility model provides an auxiliary starting device of a bomb turbojet engine in a ground joint debugging test. The auxiliary starting device comprises a high-pressure air bottle, a high-energy igniter, a battery power supply, a time relay of the high-pressure air bottle, a time relay of the high-energy igniter, a power switch and a manual switch. A high-energy igniter is adopted to ignite a combustion chamber, a high-pressure air bottle is adopted to provide air to blow a turbine, a time relay is adopted to control the opening time and the closing time of an air switch electromagnetic valve so as to control the air to blow the turbine, and the time relay is adopted to control the opening time and the closing time of the high-energy igniter so as to control the ignition time. The manual switch is used for detecting each system before starting, the electronic controller only needs to give an active IO signal to start the engine, repeated use is realized, the cost is saved, the engine can be used in any pla
