    摘要： The present invention relates to the field of space propulsion technology, and in particular, to a multi-time ignition starting apparatus for a rocket engine and a rocket engine having the same. The multi-time ignition starting apparatus for a rocket engine comprises: a thrust chamber with a first inlet and a first outlet; a generator with a second inlet and a second outlet; a turbopump assembly communicated with the second outlet of the generator , having a fuel inlet, an oxidizer inlet, a fuel outlet and an oxidizer outlet, both the fuel outlet and the oxidizer outlet being concurrently communicated with both the first inlet and the second inlet; and a fuel tank and an oxidizer tank, both having outlets concurrently communicated with both the first inlet and the second inlet, the fuel tank being also communicated with the first outlet of the thrust chamber through a first pipeline to fill a gasified fuel from the thrust chamber into the fuel tank. The present invention provides a multi-time ignition starting apparatus for a rocket engine with a light weight, a simple structure and high reliability and a rocket engine having the same.
