Jet pressing burning splitting ring curled turbine engine

Abstract

The invention discloses a jet pressing burning splitting ring curled turbine engine which comprises an external shell, an internal shell, a fan, a low-pressure compressor, a high-pressure compressor, a turbine, a combustor and a jet nozzle. The low-pressure compressor, the high-pressure compressor, and the turbine are sequentially and coaxially arranged in the internal shell which is fixedly arranged in the external shell; the fan is arranged at the air inlet end of the front side of the external shell and coaxial with the low-pressure compressor; the combustor is arranged at the tail part of the internal shell at the rear of the turbine; and a jet nozzle is arranged at the rear of an air injection outlet of the combustor. The invention provides a new working mode that the turbine drives the compressor to work and jet stream pushes an airplane to do work by respectively burning and doing work, and no energy loses in the middle link, thus reducing the aerodynamic resistance of the engine and greatly broadening the temperature and pressure limitation of the engine.

Description

technical field [0001] The invention belongs to the field of aero-engines, and relates to an aero-engine, in particular to a pressure-injection split-combustion toroidal-curved turbine engine suitable for various types of aircraft. Background technique [0002] Since the British Whittle invented the first centrifugal turbojet engine in 1941, human aeroengines have entered the era of turbines. After nearly 70 years of development, turbojet aeroengine technology has made great progress, derived turbojet, turbojet A series of engines such as fans, turboprops, and turboshafts, no matter how the purpose structure changes, the use of turbine rotation for compression and workmanship is the core technology of the engine. In order to improve the performance of the engine, people continue to increase the temperature and pressure in front of the turbine, so that the turbine can work in an extremely harsh environment. In addition to the progress of the aerodynamic technology of the engi...

AI Technical Summary

Problems solved by technology

[0004] The turbine structure of a modern aero-engine is an axial-flow blade type, consisting of dozens of turbine blades connected to a turbine disk. Large aero-engine turbine blades have hundreds of pieces. Due to the poor structural strength of the turbine blades, the tolerance The temperature and pressure are limited, and it is an open turbine, which needs to consume more compressed air and more fuel, which is not conducive to the high-speed airflow dynamics of the engine. There are also radial turbine engines in other fields, although the consumption of fuel air is relatively small , but there are also cases of low power and turbine blade strength life
