Teamwork Leads to Record-Setting Engine Test at Arnold
(Source: US Air Force Material Command; issued Nov. 6, 2009)
ARNOLD AIR FORCE BASE, Tenn. — The J-2 Test Team here completed all of the customer’s mission objectives and set a new record for the longest continuous engine test period (52.5 hours) while testing the F135-PW-100 engine.
The results of this test were critical to the qualification of the engine for the Air Force’s new F-35 Lightning II fighter.
That team comprised of Arnold Engineering Development Center engineers – Air Force and contractors alike – craftsmen, data analysis engineers and investment experts recently conducted both an altitude performance and qualification test on an F135 engine.
According to Aerospace Testing Alliance’s (ATA) Jeremy Morris, J-2 F135 lead project engineer, the entire J-2 test team, which included the 717th Test Squadron, Joint Strike Fighter (JSF) Joint Programs Office (JPO), ATA and Pratt & Whitney (P&W), more than approximately 50 hours of required mission objectives remained as the engine entered the final week of testing.
“There were concerns that some of the objectives would be postponed or dropped due to test window constraints presented by the scheduled TEDAC facility outage,” Morris said. “The entire test team did a fantastic job of identifying the highest priority objectives, coordinating support, developing a plan, which maximized test efficiency and executing that plan with an amazing level of precision.
John Kelly, the Air Force manager for the project, said this test was important when looking at the acquisition road map of the whole JSF program.
“This test was not just on a specific engine, per se, or just the F135 program, but this qualification test affects the whole JSF program,” Kelly said.
This particular test was in support of the Air Force and Navy version of the F135 Conventional Take-Off and Landing variant and Carrier Variant (CTOL/CV) Initial Service Release (ISR) Qualification for the JSF program.

Good news. 😀
I haven’t accused for for saying such things. And by that I can just return the “stop wtisting words on other’s mouth.”, because its your metiert monsieur.
Is that SO? Who alleged that some people were making claims of superiority?
YOU or I? :diablo:
while people are quick in claiming it’s better than Typhoon
YOUR comments.
For someone with consistent grammar and spelling errors and a tremdous ability to misread what is stated you shouldn’t be to loud.
See what Loke and you wrote:
Loke
So yes YOU wrote it at least and didn’t alter Loke’s question at all.
Yet more stwist and spin. 😀
Grammar has little to do with reporting FACTS accurately does it? AND you are most welcome to stop twisting words on other’s mouth.
Anyway.
F-119-PW-100 ARE optimised for supercruise.

No need for loosing yourself and the readers in the longest, most irrelevant answer you can come up with.
The guy is a qualified combat and test pilot with experience in M 2.2 aircrafts, his opinion is based on precisely what you don’t have.
Appart for one who flew both types (never read about one), there arent many people more qualified than he is to give an expert opinion and i’m sorry to say, that you can’t pretend be anywhere near as being on this (very short) list.
It’s funny as you always manage to get other writers down whatever their (much superior) experience and knowlege… :rolleyes:
Aux Francais.
Y’a des nazes sur terre…
Vu les commentaires en cours sur certain forums, je me demande si ca vaut le coup qu’un pilote d’essai et de combat dote d’une experience assez rare pour etre soulignee, quelque soit sa nationalite, ne donne son opinion si des qu’elle est positive est suspectee d’avoir un lien quelconque avec des intentions non avouees.
C’est tout simplement degeulasse.
Si on continue a cracher dans la soupe, on va non seulement passer pour des cons mais aussi perdre le peu de support qu’on peut trouver au Royaume Uni, il y a des gens dans ce pays qui savent reconnaitre les qualitees de cet avion et sont assez passiones pour faire abstraction du fait qu’il ait ete dessine et concu en France.
Peter Collins s’est vraiment eclate a voler sur le Rafale.
Ouais, il a vraiment l’air de s’etre emmerde…
!
Perhaps you volunteer to contact Thales to ask them? 🙂
Already done and not only Thales.
The GIE doesn’t give MORE than is published. EVER. 😡
obligatory
It depend what time in the day you ask them…
Exactly, their PR and technico-commercials have a strange clocking record to say the least.
Check the REAL definition of supercruise by L-M.
The Raptor’s combination of stealth, integrated avionics, maneuverability and supercruise (supersonic flight without afterburner)
http://www.lockheedmartin.com/news/press_releases/2004/LOCKHEEDMARTINROLLSOUTFIRSTFA22RAPT.html
:diablo:
NOTE: supercruise speed and super-agility are constantly quoted in ALL of Lockheed Martin doc for F-22, appart for this being more maneuvrable and faster (even supercruising in full A2A configuration) than F-35 doesn’t help.
But it would have been FAR better to give it to someone who could make meaningful comparisons with Rafale’s competitors.
Well, we were sort of expecting this one to come sooner or later… :rolleyes:
What exactly is the F-35’s drag profile, seeing as how you seem to know its aerodynamic limits? How much drag do you suppose 2 EFTs and 8 missiles causes vs. a clean aircraft?
Aerodynamic design points:
Critical Mach defines supersonic DRAG and F-35 sweep wings indicated a lower critical Mach than F-16 (33* vs 40*) in the Mach scale, as defined by their respective wingsweep, with a much larger frontal area this also mean that F-35 is much less likely to fly supersonic in Military power when F-16 is technicaly not doing it.
Supersonic means that the whole of the airframe IS supersonic (no it doesn’t occur all at the same time) and F-16 Critical Mach shows it is only fully supersonic at M 1.15, 0.05 Mach above what it is capasble of is stablelised, military power flight regime.
F-35 wing profile is supercritical and optimised for transonic flight regimes, the fact that is also uses variable wing camber to minimise drag at all speed doesn’t change the supercritical wing own characteristics.
Well if LM defines SC as >M1.5,
L-M can define what they want (and btw they DON’T define supercruise as being M 1.5), this is PR vs the own USAF Flight-test Centre definitions of the words CRUISE and SUPERSONIC.
then them saying the F-35 doesn’t supercruise just means that it won’t cruise at >M1.5.
It only means you don’t know what cruisng means.
It doesn’t mean that it won’t cruise at >M1. In other words, one can’t use their statement as proof that it can’t cruise above M1.
It means its engine, wing profile and inlets are as is known optimised for lower Machs and ceilings.
“Supercruise – the ability to fly faster than 1.5 times the speed of sound without using fuel-guzzling afterburners – is another amazing technology employed by the F-22, ” Luedke continued. “Supercruise gives a Raptor pilot the ability to fly very fast, very far, very deep into an enemy’s territory, and reduces that enemy’s ability to quickly or effectively react to an F-22 attack. Stealth plus supercruise means the F-22 likely won’t be seen, but if it is, a Raptor pilot will be able to quickly react when confronted with either surface-to-air missile or airborne threats”.

This quote doesn’t define Supercruise as being M 1.5 but says: the ability to fly faster than 1.5 times the speed of sound without using fuel-guzzling afterburners – is another amazing technology employed by the F-22.
Meaning F-22 supercruise at M 1.5.
The F-22 is the only aircraft that blends supercruise speed, super-agility, stealth and sensor fusion into a single air dominance platform.

Andwe understand that super-agility is part ofF-22 strength too.
That is the definition that they use though
SHOW us.
Just in case you haven’t noticed yet, Edwards are writing the USAF user books and are fully part of the USAF, i do not imply YOU lied but i say it is a lie.
Any quote for that?
NO but commentary made by those who asked the Rafale M pilot at the last Paris A-S.
Hence my comments on the reactions…
According to our pilots Typhoon is not superior to Rafale in any role but when we say so, we are told that they are braging about it and suggested they lie.
I suppose the French guy who did repport this will confirm, BTW this kind of thing was also a find made by USAF exchange pilots flying Mirage 2000 5Fs vs their own USAF Squadron F-15 Cs some years back.
Something else, we got figures with different configurations for Rafale supercruising (external supersonic tank, plus 4 MICAs) from one of the programe managers (Same place and time) and yet nothing on Dassault-Aviation website appart from pilots comments on their FoxOne PDF…
Loke is not making ANY claim as you alleged, he is quoting other comments and you are most welcome to stop wtisting words on other’s mouth.
So yes YOU wrote it at least and didn’t alter Loke’s question at all.
And definitively NO.
My comment is NO claim for superiority; I ALSO repport other comments and make CLEAR what they thaught about it and the reaction those who repported them got from people like yourself:
According to our pilots Typhoon is not superior to Rafale in any role but when we say so, we are told that they are braging about it and suggested they lie.
Is NOT a claim for Rafale to be superior, it says what was is writen.
Get yourself an Oxford Scorpion. 😎
Remember that the definition that the USAF and LM are using for supercruise is >M1.5(not just >M1).
I know MUCH better than that blatant lie.
CRUISE as defined by the USAF Flight-Test Centre Edward AFB and “Super”-Cruise are NOT defined by Mach but throttle setting and the resulting BEST Speed/Mach/Consumption ratio at a Cruising altitude/ceiling.
The word “SUPER” defines the flight regime as SUPERSONIC.
Try again to take people for ignorants if you wish, supercruising doesn’t evolve around the performances of the F-22 and is nothing new.
Supercruising performances were already reached by 1963 Avon Mirage III (Mach 1.3) and the Mirage 2000 supercruise as its low Critical Mach values allows it to be fully supersonic from as a low Mach as 1.1, which btw is not technicaly the case of ANY Block of F-16 with a supersonic region starting 0.05 Mach later up the Mach scale. 😉
Something else, since they could SUSTAIN their respective speeds, it is still much debatable that SR-71 and Mirage IV could “supercruise” at their respective crusing Machs of 3.2 and 2.0 unsing After Burners, this for a longer time then F-22 can at any Mach today, just a thaught.
As a 1989 ETPS graduate, and later OC flying at RAE Bedford you can add Jaguar, Hunter and Canberra to the tally, as a definite, and would expect some or all of Phantom/Tornado/Buccaneer/Teen series during his ETPS course. That’s probably when he flew the Mirage 2000.
You forgot some in the list…
Freshly posted to Germany as an RAF Harrier GR3 ground-attack pilot, Collins was recalled to the UK after the war broke out and diverted to the Fleet Air Arm for a short tour flying the Sea Harrier. Type conversion was conducted with 899 NAS at RNAS Yeovilton in Somerset between June and July 1982.

I don’t think he flew them all but just a question:
What exactly is your own credential as a combat or test pilot for jets?
Nice and informative article. But has this guy ever flown in a Typhoon? Just ask because there was no hint of it in that article, while people are quick in claiming it’s better than Typhoon:rolleyes:
Sorry i haven’t seen anyone making such a claim (did you?).
But YOU are quick in claiming that people are claiming it’s better than Typhoon.
😎
Jacko, where are you ? 😀
Oh please…
Don’t call for yet more ghost contacts who are going to tell us that the basic empty weights means empty weight, that this guys don’t know what he is talking about, that he is fundamentaly biased and known for his Xenophobia, nationalistic tendencies and insults, that crack appears on Rafale airframes at the same time they appears on Typhoon, that Rafale couldn’t S-C in Singapore, that NASA/SAAB/Dassault-Aviation aerodynamics researches finding close-coupled canard better are schoolboys, that there is only one authority in the subject suggested by the fact that he is the one who knows DGA Flight-test pilot capitaine de frégate de réserve François Duflot, that the RIAT juges can’t distinguish the best display, and….. the rest of it. :diablo:
