Abstract

The invention discloses a vertical streamline tunnel wheel gas turbine, and belongs to the field of gas turbines. The vertical streamline tunnel wheel gas turbine comprises a gas compressor, a combustion turbine, a shaft and a combustion chamber, wherein the gas compressor and the combustion turbine are installed at the upper end and the lower end of the shaft to form a gas turbine rotor, the combustion chamber is located between the gas compressor and the combustion turbine, and the shaft is vertically arranged to form a vertical structure. The vertical streamline tunnel wheel gas turbine adopts streamline tunnel turbines and gas compressor wheels, is mounted in a vertical structure in cooperation with an external contour type air bearing, and can achieve the beneficial effects of improving the rotating speed, improving the reliability, reducing the leakage loss, reducing the size and the weight and the like.

Description

technical field [0001] The invention relates to the field of gas turbines, in particular to a vertical streamlined tunnel wheel gas turbine. Background technique [0002] Gas turbines can convert the energy of fuel into mechanical energy and directly output rotational motion. They are often used in generators, ship power, aviation power, etc. Its working process is that the compressor continuously compresses air and sends it into the combustion chamber, and the high-temperature gas formed after being mixed with fuel flows into the turbine to expand and do work, driving the turbine and driving the coaxial compressor to rotate. [0003] Traditional open and semi-open blade structure impellers have tip clearances, and the number and thickness of blades are limited by the level of material technology and there is no room for optimization, which limits the further improvement of the aerodynamic performance of turbines and compressors. At the same time, the tip clearance leakage ...
