ge航空的经典发动机都是那些大家伙吗？不一定。j85就是如此：它ge历史上最成功、使用时间最长的军用喷气发动机之一。注意：别和普惠的j58（sr-71“黑鸟”的心脏）混淆哦！ j85从1954年开发，到1988年停产，累计生…

This version of the J85 became the J85-GE- increase in the mission severity factor for low-cycle 21, and was flown on a modified F-5B on March fatigue. The management and premature retirement 28, 1969. The -21 became the production engine of …

2025年3月17日 · 中科院已針對空軍除役的f-5e戰機所留下的j85-ge-21型發動機，改良成為長程巡弋飛彈的動力所需進行規畫，據指出，經過空軍盤點j85-ge-21型發動機庫存與備用零組件，約可整併出約300多具的可用發動機；但解決了長程巡弋飛彈動力的來源，並不代表中科院就一定會發展出來，因為最重要的長程導航 ...

The J85-21 is a lightweight, single-spool turbojet engine with a rated nonafterburning thrust of 15.5 kN (3500 lbf). The engine has a nine-stage axial compressor with variable inlet guide vanes and variable stators for the first three stages. It has an annular combustor, a two-stage axial-

j85-ge-21c型發動機由美商ge公司所製造，為軸流式渦輪噴射發動機，有九級軸流進氣式壓縮器，壓縮比8:1，環型燃燒室，二級同 ...

装备f-5e的j85-ge-21。 1959年4月T-38“首飞”。 它装备了2台J85-5A（经PMP改造后的J85-5R）加力式涡轮喷气发动机，干推力：2050lb（9.1 kn），每个带加力燃烧室的推力：2900 lbf（12.9 kn）。

通用电气公司的j85－ge－21涡轮喷气发动机，与先前的j85－ge－13发动机相比，具有体积小、重量轻、推重比大、维修简便、安全性高以及价格低廉等特点，但也存在一些缺点，其中最大的不足就是推力仍然不足. j85系列涡轮发动机是一种单轴轴流式发动机，分为八级压缩与九级压缩两大类。

In 2001, the USAF awarded a $601 million contract for hardware kits to upgrade 1,202 J85 engines powering the ageless T-38 Talon trainer. The upgrade kit, including a redesigned compressor rotor and stator assembly, an improved HPT, and new afterburner liner, was intended to extend the J85 service life well into the 21 st century. And that’s ...
