Abstract: PURPOSE: A boot drive of an engine of a liquid propellant rocket is provided to operate a turbine using a gas generator by supplying air to the gas generator. CONSTITUTION: A boot drive of an engine of a liquid propellant rocket comprises a fuel feed pump(120), an oxidant feed pump(130), a gas generator(140), a turbine(150) and compressors. The fuel supply pump supplies fuel to a combustor(110). The oxidizer supply pump supplies oxidizer to combustor. The gas generator generates gas by receiving a part of the fuel and the oxidizer provided from the oxidizer and the oxidizer supply pump. The turbine receiving the gas generated in the gas generator rotates and operates the fuel supply pump and the oxidizer supply pump. The compressor directly offers the high pressure to the gas generator at starting.
