Embodiment Construction
[0029] figure 1 It is a schematic diagram of the engine structure, including a low-pressure compressor 1, a high-pressure compressor 2, a combustion chamber 3, a high-pressure turbine 4 and a low-pressure turbine 5. When the engine is working, the air is compressed by the low-pressure compressor 1 and enters the high-pressure compressor 2. The high-pressure air then enters the combustion chamber 3 to burn with fuel. The high-temperature and high-pressure gas formed after combustion enters the high-pressure turbine 4 and low-pressure turbine 5, and passes through the turbine. Work is done to drive the high-pressure compressor 2 and the low-pressure compressor 1 respectively.
[0030] Such as figure 2 As shown, the combustion chamber 3 adopts a single-annular cavity structure, and the casing 6 outside the combustion chamber and the casing 7 inside the combustion chamber constitute the outer contour of the combustion chamber, and are connected with the high-pressure compressor ...
