涡轮作为航空发动机的核心部件之一,由旋转的动叶和静止的静叶组成,位于燃烧室和尾喷管之间。其作用是将燃烧室喷出的高温、高压燃气热能转变为涡轮轴上的机械能,以带动进气道风扇、压气机、螺旋桨等附件。本文通过系统的介绍航空涡轮的分类、性能指标、现状及未来发展趋势,加深对涡轮部件的研究,推动我国航空发动机事业的发展。
As one of the core components of aeroengine, the turbine consists of rotating buckets and stationary vanes between the combustion chamber and the tailpipe. Its role is to convert the high-temperature and high-pressure gas heat emitted by the combustion chamber into mechanical energy on the turbine shaft to drive the intake fan, compressor, propeller and other accessories. This article systematically introduces the classification, performance index, current situation and future development trend of aviation turbine, deepens the research on turbine components and promotes the development of aero-engine business in our country.
