普惠和GE公司准备为拟议中的波音747客机的发展型合作研制新发动机,这表明在当前利润率降低和市场竞争激烈的状况下如何回收新发动机研制费用的发展问题。根据协议两公司将为波音747-500X/600X研制推力为320～374干牛的全新的发动机。这种发动机不采用PW4000或GE90发动机作基准,但将采用全新的迄今还未确定的核心机。据称这种发动机或发动机系列也可用于其他商用飞机。
Pratt & Whitney and GE intend to develop a new engine for the proposed development partnership for the Boeing 747, which shows how to recover the development costs of new engine development costs as the current profitability declines and the market becomes more competitive. Under the agreement, the two companies will develop a new engine for the Boeing 747-500X / 600X with a thrust of 320 to 374 dry cattle. This engine does not use the PW4000 or GE90 engine as a benchmark, but will use a new hitherto undefined core machine. It is said that such engines or engine series can also be used on other commercial aircraft.
