Abstract

The invention discloses a gas compressor multi-rotor impeller and turbine multi-rotor full contra-rotating aero-engine. According to the aero-engine of the new concept, a central hollow shaft is arranged as a longitudinal framework of the aero-engine, and a contra-rotating power shaft in the hollow shaft penetrates through the aero-engine front and back, so that the aero-engine has the advantages that power can be conveniently output front and back, the aero-engine has full coverage of the functions of a turbojet aero-engine, a turbofan aero-engine, a turboshaft aero-engine, a turboprop aero-engine and a gas turbine, and the front end of a gas compressor is provided with a front-pointed-cone-shaped network-shaped high-strength protective cover to prevent impact of birds, ice, snow and sundries. A two-stage folding type conical air duct is arranged on the periphery of the air compressor in a sleeving mode and used for adjusting the windward area, stamping air inlet adjustment is achieved, and the aero-engine has the function of a scramjet new conceptual aero-engine. Dynamic structures of work conversion, power transmission and the like of the aero-engine with the new concept are all suitable for upgrading of gas turbines, steam turbines, air compressors and water turbines.

Description

technical field [0001] The invention relates to an aero-engine, in particular to an aero-engine in which multi-rotor impellers of a compressor and multi-rotor turbines of a turbine are fully counter-rotating, and belongs to the technical field of aero-engine new manufacturing technology. Background technique [0002] Aero-engine development has experienced many technological breakthroughs and industry changes in the past 100 years. From military to civilian use, great progress has been made in related industries, and engines such as pistons, turbojets, turbofans, turboprops, and turboshafts have come out one after another. Due to the characteristics of high technology, high investment, long cycle, and high risk, the world's aero-engine industry has formed an obvious and typical oligopoly pattern. [0003] In the 20th century, aero-engines have developed to a new level. For this reason, we conducted in-depth research on the collected data and pictures, referred to the evalu...
