The invention provides a method and device for improving the efficiency of a turbine engine. Involving rotor, engine. Replace the turbine rotor with the helical rotor, and make the turbine engine into a hydraulic helical rotor engine, a gas helical rotor engine, a steam helical rotor engine, or a compressed air helical rotor engine, so that the flow of the working medium in the helical tube of the helical tube rotor The direction changes continuously, and the energy of the fluid working medium is converted into mechanical work and output power. Reduce the energy loss of the flowing working medium that is not related to the work process. If the reduction of working fluid flow caused by the reduction of installed power can be dealt with by reducing the number of spiral tubes of the spiral tube rotor and or the diameter of the screw tubes, the diameter of the screw tube rotor should not be reduced. The efficiency of these engines can be increased by more than 5% respectively. The gas helical rotary engine and the steam helical rotary engine can be used as conventional vehicle engines.
