The Pratt & Whitney JT8D is a low-bypass (0.96 to 1) turbofan engine introduced by Pratt & Whitney in February 1963 with the inaugural flight of the Boeing 727. It was a modification of the Pratt & Whitney J52 turbojet engine which powered the US Navy A-6 …

Pratt & Whitney introduced the JT8D to commercial aviation in 1964 with the inaugural flight of Boeing's 727-100 aircraft. The JT8D engine has proven itself to be a highly durable and reliable engine, having completed more than 673 million dependable flying hours since entering service.

2015年5月5日 · 1964年，装载着普惠jt8d发动机的波音727-100客机完成了它的首飞。 该系列发动机共有8个型号，推力范围为62～76千牛。 除了为麦道MD-80飞机提供推力，JT8D发动机还为麦道DC-9客机、法国宇航公司SE210“快帆”客机和首批波音737客机提供动力。

波音737-jt8d，是波音737飞机的一个型号。2009年7月29日，根据《商业周刊》的统计，波音737-jt8d因致命事故间隔时间（某机型安全飞行总时间，下同）只有50.7万小时。

The JT8D is an axial-flow, dual spool, fully ducted turbofan engine. It's design dates back to 1960 Some of the certification milestones are as follows. 1988 saw the end of production of the JT8D -7 thru -17's with 11,878 units being produced. Those produced by dash models are:

2020年6月11日 · 初代737的发动机和DC-9以及727一样，都是普惠的JT8D。当年的普惠如日中天，在美国航发市场绝对统治地位。波音要求普惠做一款更大涵道比，更高效省油的发动机，再配合其它更新，增加737的产品力出一代更新款再大卖，也就是737第二代Classic。
