Embodiment 1

[0047] A combination engine with changing impeller boundaries, such as figure 1 As shown, it includes an impeller compressor 1 and a turbine 2, and the impeller compressor 1 communicates with a variable boundary fluid mechanism compressor 3, and the variable boundary fluid mechanism compressor 3 communicates with a combustion chamber 4, and the combustion chamber 4 communicates with a combustion chamber The turbine 2 is connected; the impeller compressor 1, the variable boundary fluid mechanism compressor 3 and the turbine 2 are set in linkage.

Embodiment 2

[0049] A combination engine with changing impeller boundaries, such as figure 2 As shown, the difference from Embodiment 1 is that the combined impeller-change engine also includes a boundary-change fluid mechanism expander 5, and the boundary-change fluid mechanism expander 5 is arranged between the combustion chamber 4 and the turbine 2. between.

Embodiment 3

[0051] A combination engine with changing impeller boundaries, such as image 3 As shown, on the basis of Embodiment 2, the compressor 3 of the variable boundary fluid mechanism and the expander 5 of the variable boundary fluid mechanism are arranged on the same variable boundary fluid mechanism shaft 6, so that the impeller compressor 1 and the The turbine 2 is arranged on the same impeller shaft 7, and the variable boundary fluid mechanism shaft 6 and the impeller shaft 7 are set in linkage through gears.

[0052] As a changeable embodiment, the variable boundary fluid mechanism shaft 6 and the impeller shaft 7 are set in linkage through a chain.

Abstract

The invention specifically discloses an impeller boundary-variable combined engine, comprising an impeller compressor and a turbine. The impeller compressor is communicated with a boundary-variable mechanism compressor; the boundary-variable mechanism compressor is communicated with a combustion chamber; the combustion chamber is communicated with the turbine; and the impeller compressor, the boundary-variable mechanism compressor and the turbine are arranged to be in linkage. According to the impeller boundary-variable combined engine disclosed in the invention, a corresponding boundary-variable mechanism is arranged between the impeller compressor and the combustion chamber and / or between the combustion chamber and the implementing turbine; and since the boundary-variable mechanism has a high pressure ratio (and a high expansion ratio), the performance of the engine can be greatly improved.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a combination engine with changing boundaries of impellers. Background technique [0002] Gas turbines, turbojet engines, turbofan jet engines and turboshaft engines are widely used, but due to their low pressure ratio, their efficiency or thrust-to-weight ratio are seriously affected, so a new type of engine needs to be invented. Contents of the invention [0003] In order to solve the above problems, the technical scheme proposed by the present invention is as follows: [0004] Scheme 1: An impeller variable boundary combined engine, including an impeller compressor and a turbine, the impeller compressor communicates with a variable boundary fluid mechanism compressor, and the variable boundary fluid mechanism compressor communicates with a combustion chamber, and the combustion chamber It communicates with the turbine; the impeller compressor, the variable boundary f...
