民用涡桨发动机发展综述

Feature, Current Status and Marketable Analysis of Civil Turboprop

民用涡桨发动机在50年代得到迅速发展和广泛应用。60年代涡扇发动机投入使用,使涡桨发动机处于缓慢发展阶段。70年代西方发生能源危机,用于30～50座的支线飞机的涡桨发动机再次得到发展。90年代的支线飞机市场需要较大航程和较高速度及较多座位数的支线飞机,涡扇发动机适合用于这种飞机,相对来说,涡桨发动机又处于缓慢发展阶段。

The modern civil turboprop uses the turbofan' s technologies proved in service, such as the FADEC and single crystal blades etc. and has the better reliability, endurance and maintainability. Its power increases continually as the airline requires the longer range and higher speed regional/ commuter turboprop aircraft. The paper also describes the current status and marketable analysis about the engine, and the main turboprop manufacturers.
