Embodiment 1

[0042] This embodiment provides a shaftless modular turbine engine, the working principle is as follows figure 1 shown.

[0043] When the engine is working, the turbine work is converted into electrical energy through a superconducting generator, and then the compressor is driven through a superconducting motor. Fan, compressor, and low-pressure turbine all adopt counter-rotating structure. Diverter I, Diverter II and tail nozzle are all adjustable. Diverter I adjusts the internal and external flow after the fan, and Diverter II adjusts the internal and external flow behind the high-pressure turbine. Each part is a self-contained module.

[0044] When the Ma number is less than 1.5, the air flow passes through the fan and splitter I and then divides into inner and outer parts. The outer air flow directly flows into the nozzle, and the inner air flows out after passing through the compressor, combustion chamber, high-pressure turbine, interstage combustion chamber, low-pressur...

Abstract

The invention belongs to the technical field of turbofan engines, and particularly relates to a shaftless electric transmission turbine engine. Compared with a traditional turbine engine, energy transmission is achieved between a turbine and a fan / compressor through rigid shaft torque transmission, a rigid shaft is removed, the turbine drives a superconducting generator to generate electricity, asuperconducting motor drives the fan / compressor to rotate, and energy generation and use decoupling is achieved. In the abovementioned way, all components can be independently controlled, all the components can achieve the optimal performance under different working conditions, and the working efficiency and the stable working margin of the engine are greatly improved. Liquid hydrogen is adopted for cooling the superconducting generator / motor, and the low-temperature working environment of the superconducting generator / motor is maintained; and the cooled liquid hydrogen serves as fuel to be used, cleanliness and no pollution are achieved, and the environment friendliness is improved.

Description

technical field [0001] The invention belongs to the technical field of turbofan engines, and in particular relates to a shaftless electric transmission turbine engine. Background technique [0002] In traditional turbine engines, rigid shaft torque is used between the fan / compressor and the turbine, and better overall performance is achieved by matching power, flow, and speed. In this case, it is difficult for each component to achieve the best performance under all working conditions at the same time. In order to improve the matching of the engine under different working conditions, adjustment measures are added to each component, such as adjustable stator, adjustable nozzle, gear fan and other technologies, so as to achieve the optimal performance of each component under multiple working conditions. However, the adjustment effect of these control means is limited, and it is still unable to achieve the best performance of each component in each working condition, and it gr...
