Contrarotating rotary spraying engine

Abstract

The invention provides a contra-rotating rotary-jetting engine which can remarkably raise heat efficiency and reduce pollutant emission, manufacturing cost as well as maintenance cost. The engine works by utilizing a principle that a rotary jet turbine of the engine ejects fuel gas at high speed from a tangential spout to allow the self of the rotary jet turbine to rotate reversely so as to convert fuel gas internal energy into mechanical energy; meanwhile, the engine also utilizes a tangential impact turbine to recycle the kinetic energy of the fuel gas ejected from the rotary jet turbine, utilizes a heat regenerator to realize regenerative cycle, adopts a contra-rotating axial flow and contra-rotating centrifugal pressure gas technique to obtain high total pressure ratio, adopts a rotary flame tube technique to obtain high fuel gas temperature in front of the turbine, adopts the novel structural design to greatly reduce the number of components and the consumption of precious materials, and adopts a power confluence mechanism of a cone gear and an overrunning clutch to realize the power confluent output of the mechanical energy of the rotary jet turbine and the tangential impact turbine. Therefore, the engine has high energy conversion efficiency, low manufacturing cost and pollutant emission.

Description

Technical field [0001] The invention relates to a shaft power engine, in particular to a shaft power engine used for vehicles, ships, aviation, generator sets and engineering machinery. Background technique [0002] At present, the performance goals pursued by the known shaft power engines are: as high as possible heat engine efficiency, as low as possible exhaust pollution and manufacturing cost. For a turboshaft engine, the way to achieve high thermal efficiency is to increase the total boost ratio and increase the gas temperature before the turbine; the way to achieve low exhaust pollution is to improve combustion efficiency; the way to achieve low manufacturing cost is to simplify the structure, Reduce material cost and process cost. However, the compressor of a traditional turboshaft engine adopts a single-rotating rotor blade and a stator blade to form a single-stage compression stage. The working environment of the canister and turbine is even harsher, and the high ...
