普惠加拿大公司已成功地研制了JT15D和PW300涡扇发动机,为了提高在通用航空发动机市场的竞争能力,并占领更多份额,该公司于1992年开始设计推力为13.3～17.8千牛的PW500发动机。计划简况普惠加拿大公司在80年代中期对通用航空市场进行了调查,结果表明需要研制在高空时耗油率比装目前公务机加长型的现有涡扇发动机的低10%～15%的发 Pratt & Whitney Canada has successfully developed the JT15D and PW300 turbofan engines. In order to increase its competitiveness in the general aviation engine market and occupy more share, the company began designing the PW500 engine with a thrust of 13.3-17.8 kN in 1992 . Program Briefs Pratt & Whitney Canada surveyed the general aviation market in the mid-1980s and found that there was a need to develop fuel-efficient systems that consume 10% to 15% less fuel than conventional turbofan engines currently available in official jets
