摘要
自1990年PW4084发动机计划启动以来,普拉特·惠特尼(以下简称普惠)公司一直在贯彻一项8点设计发展计划,其目标是:在推力为374千牛(84000磅力)的PW4084发动机装波音777飞机投入航线使用之际即具有180分钟双发飞机延程飞行(ETOPS)所必须的、且得到验证的可靠性和性能。8点设计发展计划8点设计发展计划的实质是:通过8道逐步“筛除”掉或减少使用中可能出现的问题。该计划包括以下四个方面的内容,即衍生发动机。
Since the PW4084 was launched in 1990, Pratt & Whitney has been pursuing an eight-point design and development strategy for the engine . The eight-point program should be thought of as a serise of' filters'. The development program and all its associated problems pass through successive filters until production engines are ready for service entry, The program includes the folio-wing aspects : derivative engine, smarter design , tougher testing and customer prepared, screening out service problems and ensuring product to meet expectation .
