Method and device for improving efficiency of turbine engine

Abstract

The invention provides a method and device for improving the efficiency of a turbine engine and relates to a rotor and an engine. According to the method, turbine rotors are replaced by screw pipe rotors; the turbine engine is manufactured into a hydraulic screw pipe rotor engine, a gas screw pipe rotor engine, a steam screw pipe rotor engine or a compressed air screw pipe rotor engine; the flow direction of a flowing work medium in the screw pipe of the screw pipe rotor is continuously changed; the energy of the flowing work medium is converted to mechanical output power; the energy loss, irrelevant to acting process, of the flowing work medium is reduced; the amount of screw pipes of the screw pipe rotor or the diameter of each screw pipe is reduced to handle the flow decrease of the work medium caused by the decrease of installed power, so that the diameter of the screw pipe rotor does not need to be reduced. According to the method, the efficiencies of the engines can be further improved by more than 5%; the gas screw pipe rotor engine and the steam screw pipe rotor engine can be used as engines of conventional vehicles; and devices such as a ship, an aircraft, a power generation device and a conventional vehicle provided with the screw pipe rotor engine are more energy-saving and environment-friendly.

Description

technical field [0001] The present invention relates to a rotor and an engine, and further specifically relates to a helicoidal rotor engine composed of a helicoidal rotor. Background technique [0002] A turbine is an engine that uses fluid to impinge on the rotation of the impeller to generate power. It is mainly divided into four types: gas turbine engine, steam turbine engine, water turbine engine (ie water turbine), and compressed air turbine engine. When we are not pursuing the thrust of the jet flight of the turbine engine, but the efficiency of the turbine engine converting the energy of the flowing working medium into mechanical work, the energy conversion capability of the turbine engine basically determines the efficiency of these turbine engines. The turbine engines of the prior art are widely used in civil and military fields such as power generation, aircraft, ships, and power, and play a very important role. How to improve turbine engine efficiency? Reducing...

Problems solved by technology

When the speed of the gas turbine engine is low, its coaxially driven axial flow or centrifugal speed compressor will not be able to provide the corresponding gas pressure to the combustion chamber, so that the gas turbine engine cannot work normally

For gas turbine engines with output power below tens to hundreds of kilowatts, due to the small flow rate of the working medium, its turbine diameter is small, the moment arm is short, and the output torque is small. Increasing the speed and increasing the power will be detrimental to the transmission, etc. The above disadvantages It is the main reason why the gas turbine engine is coldly received in the field of vehicle engine applications, regardless of whether it has no complicated crank-link mechanism in structure or has technical advantages over piston internal combustion engines in other aspects
