weight of compressor

The development of higher efficiency and larger thrust-weight ratio of aeroengine has put a further demand on the aerodynamic performance of compressor component.

航空发动机的高效率以及高推重比的发展方向对压气机部件性能提出了更高的要求。

With nicer specific stiffness, specific strength and higher heat resistance, titanium alloy is the key material for high performance aero-engine to reduce weight and improve thrust-to-weight ratio. Thus it is widely used in fan, compressor and other components of modern aero-engines.

钛合金具有良好的比刚度、比强度以及较高的耐热性能，是高性能发动机减轻结构重量、提高推重比不可或缺的关键材料，因而在现代航空发动机风扇、压气机及其它构件中得到了广泛应用[1-3]。

Vane-type compressors have a very wide range of applications because of small size, light weight and good balance, etc. At present, it is the one of the main-types of automobile air conditioning compressor.

滑片类压缩机因具有体积小、重量轻以及动平衡性能好等优点而得到非常广泛的应用，是目前汽车空调压缩机的主流机型之一。

The performance of aero engine ( thrust-to-weight ratio, specific fuel consumption) can be improved by increasing the turbine inlet temperature and the compressor pressure ratio.

在提高压气机压比的同时，提升涡轮前温度是改善航空燃气涡轮发动机性能（推重比、耗油率）的有效措施。
