Power-driven gas compressor of novel structure

Abstract

The invention relates to a power-driven gas compressor of a novel structure. The power-driven gas compressor serves as an important component of a power-driven environment control system, and is an indispensable core product of the power-driven environment control system applied to future all-electric aircrafts. A rotor system of a civil power-driven gas compressor is commonly supported with a ball bearing, and the power-driven gas compressor supported with the ball bearing needs a special oil supply structure to guarantee lubrication and cooling of lubricating oil to a bearing, so that the power-driven gas compressor is complex in structure, large in weight and poor in ball bearing reliability at the high rotation speed, and the requirements of the power-driven environment control system are difficultly met by the power-driven gas compressor of a traditional structure. According to the power-driven gas compressor of the novel structure, the rotor system is supported with an air bearing support. The power-driven gas compressor has the advantages of being simple in structure, high in reliability, good in high-temperature high-speed performance and the like, a two-stage compression structural mode is further adopted for the gas compressor, the high supercharging ratio can be obtained on the premise that the compact structures of products are guaranteed, and the compact, efficient and weight-reduction requirements and the like of the power-driven environment control system are accordingly met.

Description

Technical field [0001] The electric compressor is an important component of the electric environment control system, and it is an indispensable core product for the future all-electric aircraft to use the electric environment control system. Background technique [0002] The electric compressor is more effective than the traditional bleed air system: it does not need to extract energy from the engine, cancels the bleed air system of the environmental control system, does not need to perform pre-cooling and pressure adjustment, resulting in energy waste, and improves the fuel compensation of the engine Loss: The compressed gas is provided by the adjustable-speed electric compressor according to the required pressure, which reduces the performance compensation loss of the aircraft and realizes the best control of the operation of the environmental control system. At the same time, it contributes to the compactness, efficiency and weight reduction of the environmental control system...

AI Technical Summary

Problems solved by technology

[0003] Electric compressors have not yet started to be used in military aircraft. The rotor system on civilian electric compressors is generally supported by ball bearings. Electric compressors supported by ball bearings require a special oil supply structure to ensure that the lubricating oil lubricates and cools the bearings. Therefore, its structure is relatively complicated, and its weight is relatively large. At high speeds, the reliability of ball bearings is poor. Therefore, it is difficult for electric compressors with traditional structures to meet the needs of electric environmental control systems.
