Abstract

The invention discloses a gas turbine motor for a rotary combustion chamber. The gas turbine motor comprises a compressor, a combustion chamber and a turbine successively arranged, wherein the final stage of the compressor is a centrifugal vane wheel; the combustion chamber comprises a rotary disc arranged on a high-pressure rotor and two or more annular combustion cavities arranged at one side of the rotary disc; a flame chamber is arranged in each annular combustion cavity, and an ignition electric nozzle and a fuel nozzle are arranged in the flame chamber; the annular combustion cavities are located at the edge of the rotary disc and at the outer side of the circumference of the centrifugal vane wheel; and a baffle plate is arranged between the annular combustion cavities and the centrifugal vane wheel. High-temperature high-pressure combustion gas directly pushes the combustion chamber to rotate and work and needs no cooling; gas exhausted at the tail end of the compressor can be used for combustion; thermal efficiency can be improved to 60% or above; and engine performance can be improved by times.

Description

technical field [0001] The present invention relates to a gas turbine engine with a rotating combustor, eliminating the need for a high pressure turbine. Background technique [0002] Modern aeroengines - gas turbine engines are known as the crown of modern industry, and high-pressure turbines, as the core components that affect engine performance, are in extremely harsh high-temperature, high-pressure, and high-speed working environments. Because of their difficulty in manufacturing and high cost, Known as the diamond on the crown of modern industry, its processing technology is regarded as the core secret, and all countries strictly restrict the export of its technology. my country's gas turbine technology has been trapped by this for a long time. [0003] Restricted by high-pressure turbine materials and processes, the temperature and pressure of the gas in front of the turbine are strictly limited. On the one hand, the boost ratio of the compressor is limited. On the othe...
