Yes, NL are partners in the JSF project. Spent 800 million euro to get in, got about 1 billion back, so far. One test plane on order, a second maybe. Major purchase decision deferred by current and last government. NL governments and KLU (RNLAF) are very U.S.A.- and Lockheed-oriented. Competitors have never been given a real chance. Budget cuts have mothballed all MBTs (Leopards) and threaten thousands of personnel layoffs, but the JSF seems above all critique.
Dear fairclought7 , you're quite right. See the "Pratt & Whitney F135" article on Wikipedia. Good pictures. The vectoring nozzle at the rear uses engine air, the vertical air stream behind the cockpit is generated by a fan driven by the turbo. Here in the NL, builders would be happy if the RR F136 succeeds, as our industry has invested in it as well.
@vhjmvn Are the NL looking at purchasing the F-35? i do hope the F136 has its fair share of the market with the F-35, i know our government and military would much prefer to use home grown engines which will be much more cost effective and economical in the long run and i for one much prefer Rolls Royce to P&W and not just as a patriotic thing but as an economical reason too, better for our economy and they are very good engines..
It's a T-shaped engine that works equally horizontal and/or vertical. Unlike in the Harrier, there's only 1 main moving outlet, in the tail; airflow can be directed down or back. This is a Pratt and Whitney engine. The Pentagon still refuses to fund the allegedly better General Electric / Rolls Royce version (RR made the Harrier and AV-8 engine). P&W's monopoly ruffles partners' feathers. GE/RR now fund further development of their engine out of their own pockets.
@vhjmvn The main engine yes but at the front just behind the pilot is a lift fan that from what ive read runs of a PTO from the jet engine and is only a fan with no heat, just cold air although now we are no longer opting for the STOVL variant and are building our carriers for cats and traps im not sure what RR will do but they will probably develop the carrier version engine as the Fleet Air Arm usually go for the RR engines as they did with the Phantom, even the Apache has RR engines
@blehblehbleh90 yes there is that too and with the BERP rotor blades too the WAH-64 is more powerful, faster more maneuverable and has a heavier payload capacity but the only problem is the original gearbox is not strong enough to fully use the extra power but the americans are looking at using the RR engine so will be upgrading the gearbox. still the WAH-64 is the only Apache capable and cleared to operate at sea from ships..

@fairclought7 The WAH-64 that is, probably just more cost effective to have home grown engines in our aircraft

@fairclought7 Not to mention the increase in power by using RR engines, as in the Apache.

What's that "open-hatch" thing behind the cockpit?
pcaledonius 4 months ago
@pcaledonius - should be an engine with vertical jet
skazhiprivet 4 months ago
@skazhiprivet A lift fan, no vertical jet in the F-35B

@fairclought7 - yes, thanks
i meant the airflow was vertical
not sure what the proper term is :)

@skazhiprivet No problem, happy to help. i only know as i read a while back that Rolls Royce actually make the lift fan..

@pcaledonius That's an opening for the hover fan. It's a big air inlet.

@Frosttty yep its a lift fan rather than a jet engine..
