The Allison J71 was a single spool turbojet engine, designed and built in the United States. It began development in 1948 as a much modified J35, originally designated J35-A-23. [1] The Allison J71 turbojet powered the Douglas B-66 Destroyer and the McDonnell F3H-2 Demon after the failed Westinghouse J40 proved unworkable.

2024年8月8日 · In the late 1940s, the Allison Engine Company created the 16-stage and 16-foot long J71 engine to succeed its TG–190 (J47). In addition to replacing the J40 engine in the F3H-2 Demon aircraft, the 10,200-pound-thrust J71 also powered the Douglas B–66B Destroyer light bomber in the late 1950s and 1960s.

Begun in 1949, the J71 was the first turbojet wholly developed by Allison, drawing on the company's technology base from its uprating of the J33 and J35 turbojets, and development of the T38 and T40 turboprops.

With jet engines, Allison's J71 won a place on the Lockheed F-94, and was tested on several other models. But by 1955, General Electric and Pratt & Whitney had achieved an insurmountable lead in powering bombers and new jetliners, such as the Boeing 707 and Douglas DC-8.

2016年10月6日 · 1951 年 12 月爱德华·M·弗雷士领导的麦克唐纳设计团队推荐 F-101 安装两台带加力的艾利逊 J71 涡喷发动机，其推力接近 XF-88A 使用的威斯汀豪斯 J34 的三倍，是生产型 F-88 计划使用的威斯汀豪斯 J46 的两倍。 但是 USAF 认为推力仍然不够，倾向于使用两台推力更大的普惠 J57 加力发动机（加力推力 7,802 千克），但需要对原设计进行重大修改。 F-101 的发动机与 XF-88 的安装位置相同，设计师重新设计并放大了翼根进气口以增加空气流量。 考虑到需 …

Allison’s total production during WWII was 70,000 engines, both reciprocating and jet, and 10 million bearings. At its peak in 1943, the plant employed 23,000 people working three shifts seven days a week. By 1943 the physical size of the company had grown from one machine shop to three modern factory buildings.
