Gas turbine jet engine with outer combustion chamber - has auxiliary nozzles and combustion chamber between compressor and turbine

摘要

Engine has an annular combustion chamber (2) surrounding the inner tube which contains the moving parts. The combustion chamber has fuel and oxygen nozzles (1) and is surrounded on the outside by a heat shield (3). It is separated from the inner space by a dividing tubular wall. The inner space contains a two stage compressor driven by high and low speed turbines. The compressed air is heated through the wall of the dividing tube in the space (4) between the compressor and the turbine and the resulting expansion produces the energy to drive the turbine. Additional nozzles (5) admit fuel and oxygen into this space and the resulting combustion increases the energy of the air which provides the engine motive power.
