Re: F-35 Joint Strike Fighter Thread

at 30% or lower the pilot is already looking for a place to land. Jet fighters are hardly fuel efficient. now your primary worry is the heat sink. since the jet is in the air already and flying she is under the effect of convection with low temperature air flowing in and around the fighter.

Not a very reassuring thing for pilot if he suddenly find himself in air combat with low fuel : "Ok, I would need to switch off my radar or it will overheat and burn out" ... If convection is enough they would not need to use fuel as heat sink , and you are not allowed to turn radar on when grounded anyway .

Re: F-35 Joint Strike Fighter Thread

yes lower fuel means less volume to absorb heat. but once your at altitude and speed F35 has Air flow. that adds Heat Convection, The Force of Air flowing over and around the Jet the Radar's Radiated heat will be dissipated into this airflow.

The Royal Netherlands Air Force changed the command of its Lockheed Martin F-35 Lightning II detachment at Eglin AFB, Florida, to 323 Sqn. The unit had been officially disbanded on 31 October at Leeuwarden air base, having previously operated the Lockheed F-16.

Now re-established in the USA, 323 Sqn will be tasked primarily with conducting initial operational test and evaluation (IOT&E) of the F-35, following its relocation to Edwards AFB in California by the end of this year.

The Dutch air force has taken delivery of two conventional take-off and landing F-35As to support the US-led IOT&E activity, and has three pilots qualified.

The F-35A is due to become operational with the Royal Netherlands Air Force during 2019, with the service expected to eventually receive another 37 of the aircraft.

The beat goes on.

Let me say something about the heating issues that are being sensationalized of late. This is not a new issue. It is something that has been accounted for for some time and has been designed to operate as it does in order to provide additional cooling at very particular points in the service envelope of the aircraft.

These people know exactly what they are doing and why...and these intial anomolies as the aircraft is being rigorously tested and policy and procedure being developed for its specific operations prior to IOC can easliy be latched onto by people who are opposed tothe program for whatever reason.

I personally do not view this issue at this point as a major issue.

As I have said before. Will there be issues? Will there be problems? Yes to both.

Will they be resolved? Yes.

Re: F-35 Joint Strike Fighter Thread

Unlike Chinese, Russian or Iranian 5th generation aircraft, the F35 is so original and it looks flawlessly beautiful from any angle.

Who would have thought people could invent something like this back in the day, what an engineering!

Re: F-35 Joint Strike Fighter Thread

More on Israel's direct approval of the purchase of 14 more F-35's which was announced in November and which now has been approved. This order also includes an option for 17 more on this contract.

These 14 bring the total number Israel has now offically approved to 33. If the option for the additional 17 is exercised (and I believe it almost assuredly will) it will bring to 50 aircraft that Israel will be buying.

In this article I find it interesting that ultimately wings for the aircraft will be built in Israel.

Israel will acquire a second batch of 14 Lockheed Martin F-35 Lightning II stealth fighters, after the nation’s cabinet approved the purchase.

One aircraft from the new batch will be a test asset, which will help during the development and integration of Israeli-dedicated systems for the type.

The decision also includes an option for a future procurement of another 17 aircraft, pending later approval.

Israel's second contract was approved in principle when defence minister Moshe Ya’alon met his then-US counterpart Chuck Hagel in Washington DC recently.

The Israeli air force has already secured national approval to purchase an initial batch of 19 conventional take-off and landing F-35As for $2.75 billion. Ordered as part of the US programme's eighth lot of low-rate initial production, the first two aircraft from this batch are due to arrive in Israel by early 2017, with the rest to follow through 2018. Preparations to introduce the type are already under way atNevatim air base in southern Israel.

Meanwhile, since signing a contract with Lockheed Martin in April 2013 for production of wings for the F-35, Israel Aerospace Industries has invested in the advanced systems and technologies required for the aerostructures’ production. A state-of-the-art automated production line has been established at IAI's main campus in order to meet the F-35 stealth design.

The company will make its first deliveries in mid-2015 under the 10- to 15-year arrangement, which it values at a potential $2.5 billion.

Re: F-35 Joint Strike Fighter Thread

This is a very serious matter if true. Can you provide citation? If the F35 is basically useless at say less than 10 or 20% remaining fuel load we would have a lemon on our hands. Even if say 80% has more than adequate range we're still talking significant overhead in terms of weight and performance penalties.

Kwai, if you're down to 10-20% fuel babe, you better be hookin up to your big sister, or findin you a spot, cause you are coming down shortly, no one operates that low on purpose. If your high, the fuel will be Kool, if you are low that won't last long, and you really do need to be looking for a spot, you're not gonna engage anybody on purpose with that fuel load!

I hope that was a typo. F22 fits the bill in your description not the F35.

True however my concern was in regards to the earlier argument about avionics or other subsystems not working optimumly due to decrease heat exchange from low fuel. The LAST thing a pilot needs to worry about when he is low on fuel is that his avionics are not working properly. That was my contention.

Both (including the F-35 which the thread is about) are good looking aircraft from most angles IMHO.

However, from the pure side profile, both US aircraft appear a little thick...but that is also a decieving notion in terms of performance.

In terms of their stealth workmanship, angles, material, etc., they are also exceptionally well crafted aircraft.

That said, I believe the J-20, the PAKFA, and the J-31 are also very well built and crafted machines. All of them suffer particularly, IMHO, from stealth features as particularly regards their engine exhausts...but all are supposed to receive more stealthy engines (as I understand it) when they get to the operational stage as opposed to the prototype stage they are at now.

I agree Kwai, but the lovely little ThunderHogge II is growing on me, kinda like the Republic P-47, a little bigger, but in some ways better aircraft. The F-35 does share a lot of DNA with the Raptor, and compared to the princess, the little ThunderHogge isn't a super-model, but more girl next door?? LOL
