jusqu'à l'arrivé du block 4, du nouveau moteur, du nouvel EOTS, etc.. autant remplacer par un avion neuf, c'est plus simple.

Directed-Energy Capability Targeted By Pratt F-35 Engine Upgrade Plan

http://aviationweek.com/defense/directed-energy-capability-targeted-pratt-f-35-engine-upgrade-plan

si pb d'accès

 

Pratt & Whitney is refining its proposed upgrade path for the F135 Joint Strike Fighter engine to include increased power and thermal management (PTMS) capability following feedback on its initially proposed upgrade package from the F-35 Joint Program Office.

Additional power and thermal management capability will enable the use of directed-energy weapons and other advanced offensive and defensive systems and, if approved, would feature in an upgrade package called Growth Option 2.0 (GO2).  Pratt & Whitney, which would roll PTMS into a suite of compressor and turbine enhancements originally proposed in the first upgrade package, G01, says the complete upgrade could be available within four years of getting the official go-ahead.

Growth Option 1.0, which was floated with the JPO in 2017, offered 5% fuel reductions and as much as 10% higher thrust. Offered as a cost neutral upgrade, it was always meant to form part of a longer term, two-stage improvement road map for the F-35 engine under plans first unveiled by the manufacturer in 2015. However, with the move to combine GO1 and 2 into a more complete enhancement package, Pratt is tailoring the revised proposal to closer match the F-35 upgrade road map recently outlined under the C2D2 continuous improvement strategy.

Planned as engine-only ‘drop-in’ replacement for F135

Growth Option 2 adds power and thermal management to original core upgrade proposal

GO1 builds on core technologies evaluated from 2013 onward using the modified F135 test engine XTE68/LF under the U.S. Navy-sponsored Fuel Burn Reduction (FBR) program. It also incorporates design improvements developed under the U.S. Air Force-supported component and engine structural assessment research (Caesar), which focused on the F119 engine for the F-22, the predecessor of the F135 powerplant.

Though focused on integrating enhanced thermal management, GO2 will leverage more of the adaptive engine technology features in development at Pratt through Air Force and -Navy-supported initiatives. These largely stem from the Air Force-led Adaptive Engine Technology Demonstration (AETD), as well as the follow-on adaptive engine transfer program (AETP), which is targeting development of the XA101 variable cycle engine for sixth-generation fighters. 

The proposed upgrade leverages some elements of the adaptive-cycle technology tested on the F135. Credit: Pratt & Whitney

The chief focus for these new AETD, AETP and XA101 engine cycles is the addition of a third air stream to provide either greater combat power or more range, depending on the phase of the mission. However, the “GO” upgrade packages can take advantage of the broader variable-cycle approach, says Matthew Bromberg, president of Pratt & Whitney Military Engines. “Adaptive refers to many other elements of the engine as well, not just the third stream. Yes, there is a third stream, but we are also looking at adaptive elements in controls and components inside the engine such as an adaptive turbine.”

“We have widened the aperture and are looking at adaptive elements across the engine,” he adds. “As these mature we will look at what we can do with the technology in an existing engine ,and that’s the concept in GO1. And GO2 is exactly the same thing. It just adds the PTMS capability which we missed last year. We didn’t have that in terms of the requirements when we packaged GO1, and that was the feedback we got from the customer. With a PTMS solution this can meet all the C2/D2 requirements, and I think that’s compelling.”

Designed to be a drop-in replacement for the current engine, the GO2 package will not require other system upgrades outside of the propulsion system. “There’s more we can do with Lockheed Martin and other suppliers if we go outside the engine, but this is all within the engine,” says Bromberg. Although providing few specifics he adds, “It is leveraging all the bleed systems, the generation systems.”

Pratt, meanwhile, continues tests of the new technology future fighter engine core, which will provide the basis for the XA101. Although the company declines to offer any details of the work, it follows the successful completion of tests of a three-stream fan system on a modified F135 under the AETD program. Results from the core tests will feed into the AETP effort that forms the basis for the XA101 engine.

Ce sont des news qui tombent au bon moment je trouve (cf le désir latent de la Luftwaffe de prendre du F35 ou le futur choix Belge).

Les clients potentiels non encore ferrés vont se rappeler que LM ne tient plus ses promesses depuis 15-20 ans (sur les coûts, les délais, les performances), et donc que le standard F4 en 2023 c'est encore de la poudre aux yeux.

Si j'étais vilain, je rappellerais le précédent des Typhoons de la tranche 1.

Et si j'étais pervers, je rappellerais aussi que les dix Rafale F1 ont longtemps représenté bien plus que 10% de notre flotte, tout en étant au rencard - rencard dont ils sont sortis à grand frais.

Les F1 çà c'est joué "aux forceps" vis à vis d'une MN qui n'en voulait pas (contexte), et qui ne regrette absolument rien aujourd'hui ...

C'est bien la peine que je prenne des précautions oratoires quand je trolle ouvertement ... :rolleyes:

Le problème, c'est que le cas de l'Eurofighter Tranche 1 n'est pas tant que cela du troll. Les autorités autrichiennes n'étaient pas tout à fait conscientes qu'il s'agissait d'un Q-Eurofighter.

Edit : Soit dit en passant, il semblerait que les Autrichiens aient eu dernièrement plus d'unités opérationnelles que les Allemands. L'un des problèmes de disponibilité sur les dernières tranches réside dans l'incapacité à refroidir le DASS et ses capteurs en raison de pertes de liquides. Or la société qui avait été contractée par le consortium Eurofighter pour fabriquer la pièce problématique doit être à nouveau certifiée par le ministère allemande de la Défense après qu’elle a changé de propriétaire. Sur le Tranche 1, pas de tels problèmes :laugh:

C'est pas spécialement les F1 dont elle ne voulait pas.  Le doute sur la pertinence d'un delta sur PA était fort... 

Et c'est tout à l'honneur de Dassault d'avoir su vaincre cette réticence (quand même assez étayée) avec le brio qu'on connait maintenant.

Le premier F-35 déclaré perdu (ou transformé en pièce de musée).

Il s'agit en fait du f-35 qui avait pris feu il y a deux ans qui ne sera pas réparé, l'investissment n'étant pas intéressant selon l'USMC.
