A shaftless gas turbine

Abstract

The invention provides a gas turbine without a main shaft. The gas turbine is characterized by comprising a housing, a rotor assembly, a stator assembly and a bearing assembly, wherein the rotor assembly and the bearing assembly are mounted in the housing, the bearing assembly supports the rotor assembly, and the stator assembly is connected with the housing; the rotor assembly comprises a rotor ring and a plurality of rotor blades, the rotor blades are arranged on the rotor ring, and the rotor ring is arranged on the housing; and the stator assembly comprises a rim and a plurality of guide blades, the guide blades are arranged on the rim, and the rim is arranged on the housing. The gas turbine has the advantages of being small in occupied space, high in energy conversion efficiency, largein output mechanical power, small in vibration and the like, and is particularly suitable for being applied to the engine technology of a new generation of advanced aerospace vehicles and modern civil airliners.

Description

technical field [0001] The invention relates to the technical field of aero-engine turbines, in particular to a gas turbine without a main shaft. Background technique [0002] Aero-engine technology has always been the focus and focus of research by countries all over the world. Every important change in the history of human aviation is inseparable from the progress of aero-engine technology. The gas turbine engine is currently the most widely used aero-engine, and has been the main form of aerodynamic power since the 1950s. It has the advantages of compact structure, high comprehensive performance, and wide stable working range. It is the best power choice for space vehicles, and in the foreseeable future, no other power form can completely replace it. [0003] However, with the needs of modern industrial construction and the development of advanced aircraft, the performance requirements of aero-engines are getting higher and higher. Researchers are constantly looking for ...

AI Technical Summary

Problems solved by technology

Increasing the supercharging ratio will lead to a decrease in the heating capacity of the air and a decrease in the specific thrust, while increasing the heating ratio is limited by the high temperature resistance of the turbine components

Therefore, the disadvantages of traditional aero-engine axial flow turbines have gradually become prominent, and they can no longer meet the performance requirements better

The traditional gas turbine with main shaft has many components, complex structure, large volume and space occupation, large energy loss, difficult vibration and noise control, high construction and maintenance costs, etc. These defects have led people to gradually turn their attention to more advanced shaftless propulsion technology
