BAe joined forces with their long Standing Harrier partners, McDonnell Douglas and together with Northrop Grumen, proposesd the JAST for the JSF requirement. The aircraft was superior in many respects to the X-32 and X-35, however it was deselected primarily because it used a separate lift jet for the B model.

2006年3月31日 · Note one of unique McDD/Northrop/BAe JAST design know-hows that team so hoped would help them to win - 'variable' internal weapons bay adoptable for carrying various AA/AG load depending on mission. To my sorrow, I can't post some images from my collection due to promises I've made.

2019年10月10日 · 麦道/诺格/BAE团队提出的JAST方案延续了YF-23的V尾布局，采用两侧进气和兰姆达（LAMBDA）主翼，在设计上极端重视隐身性能。 兰姆达主翼是一种针对隐身性能进行优化的翼形，与传统体形机翼相比其后缘呈内凹锯齿状，使机翼前后缘更加容易与机身其他边缘对齐，同时增加了展弦比并提高了空气动力学效率，由于机翼后缘外形很像希腊字母λ，所以又被称为兰姆达（Lambda）机翼。 但兰姆达机翼的后缘锯齿降低了结构效率并增加了机翼重量。 兰姆 …

2009年1月19日 · The BAE JAST was based on the BAE Replica - a stealth replacement for the Tornado that was concealed when planning realised the role would be undertaken by UCAVs and cruise missiles. I think Barry Ledge has built an x-plane version but I haven't seen it anywhere. Here's an interesting article in flight global - Stealth Meets STOVL.

2025年3月4日 · The JAST, jointly designed by McDonnell Douglas, Northrop and British Aerospace (BAE), the STOVL version uses a reheated turbofan and an auxiliary lift engine, and there are 2 auxiliary vectoring nozzles for STOVL at the rear of the body. and inefficient defeat.

In September 1993 the USAF's MRF, a planned F-16 replacement, and the A/F-X, a joint-service dual-role swing-wing deep strike fighter, were canceled. A new program, JAST (Joint Advanced Strike Technology), was established, to develop technology for a new fighter. BAe and Northrop Grumman joined MD in 1994.

2019年6月21日 · 麦道/诺格/bae团队的在jast垂直起降型上大胆采用了气体驱动升力风扇设计，通过主发动机高压引气来直接驱动风扇产生升力，这样能彻底解决升力发动机的热废气吸入问题。

2018年11月29日 · JAST案一共分成三个阶段，分别是概念验证、概念实证及工程制造与发展阶段，在1994年12月22日正式与美国当时的四大航空大厂签订合约，分别是麦道、诺斯洛普．格鲁曼、洛克希德、波音四家公司，其余还有包含数家航电系统的公司，如西屋、休斯、洛克威尔等，这份合约的签订宣告JAST案正式进入第一阶段：概念验证。 麦道公司的YF-23. 在负责机体研发的四家公司当中，格鲁曼与麦道联合英国航太公司组成一个研发团队，该团队可说是JAST计划中最 …

The JSF program has produced one of the world's best known aircraft in the F-35, and amongst aviation enthusiasts, the rival X-32 concept from Boeing is also familiar. However, back when the program was still the Joint Advanced Strike Technology program, or JAST, there was actually a third competitor from a three-way coalition.

2006年3月27日 · I worked on the McDonnell Douglas side of ASTOVL and JAST, then Boeing's JSF. The real backstory of how these are all connected (along with SSF) has somehow never been told, even though for years it was right out in the open on the jast.mil website.
