It received its FAA certification in May 1969 and entered service in January 1970 on the Boeing 747. It subsequently powered the Boeing 767, Airbus A300 and Airbus A310, and McDonnell Douglas DC-10. The enhanced JT9D-7R4 was introduced in September 1982 and was approved for 180-minute ETOPS for twinjets in June 1985.

Since entering service on the Boeing 747 aircraft in 1970, the JT9D engine has proven itself to be the workhorse for early 747, 767, A300, A310 and DC-10 aircraft models with more than 3,200 cumulative engines delivered. The JT9D engine family consists of three distinct series.

JT9D也是普惠生產的第一款高涵道比渦扇發動機，應用於波音747、 波音767 、 空中客車A300 、 空中客車A310 、 麥道DC-10 等機型。 [1] JT9D發動機最初屬於 C-5運輸機 設計方案的一部分，當時普惠與 通用電氣 正為C-5的發動機競標，普惠著手研究為大型飛機提供動力的發動機，但其競爭對手 通用电气航空 的 TF39發動機 （英语：General Electric TF39） 最終得標， 波音 後來採用了普惠的JT9D發動機以供當時正在開發的 波音747 使用。 而在波音747於1969年2月9日首飛 …

workhorse for early 747, 767, A300, A310 and DC-10 aircraft models with over 3,000 cumulative engines delivered. The JT9D has flown more than 169 million total hours to

The Pratt & Whitney JT9D engine opened a new era in commercial aviation: the high-bypass ratio engine to power wide-body aircraft. Since entering service on the Boeing 747 in 1970, the JT9D has proven itself to be the powerhouse for early 747, 767, A300, A310 and DC-10 aircraft models with over 3,000 cumulative engines

JT9D (JT9D-3 & JT9D-7) engines are manufactured by Pratt & Whitney for Boeing 767-200,-200ER,-300 & 747-100, 747-200 & 747-300 aircraft and Airbus A300 & A310 aircraft which were produced from 1968 - 1990. Thrust rating ranges from 48,000 lbs. to 54,800 lbs.

Since entering service on the Boeing 747 in 1970, the JT9D has proven itself to be the workhorse for early 747, 767, A300, A310 and DC-10 aircraft models with over 3,000 cumulative engines delivered. The JT9D has flown more than 169 million total hours to date.

2012年1月19日 · However, some 767 operators actually wanted to use JT9D's on 767s (for crossfleeting with their older 747s). Boeing caved, and you had a few 767's built with JT9Ds

The JT9D, PW4000, CF6-50C2 & CF6-80C2 series are the most numerous widebody engines and power the same and similar aircraft types. Maintenance costs analyses for each type have been updated and reserves compared between the four families.
