Кусочки  одной из многих  обзорных статей в автралийском спецжурнале, кстати  в австралии не смотря на то что они подписались на F-35 много старонников “рептора”. К  проекту  F-35 местные военспецы и аналитики  без явного оптимизма относятся. Очень сильно опасаются  Китая с Су-27 ну и Японии недоверяют, понимают расклад сил в южно-восточной азии меняетя и юса будет их сливать если вспыхнет кофликт интересов, англо-саксы это прогматики и в  этом их сила, ну  и слабость конечно.
Supercruising Flankers?
Asia Pacific Defence Reporter, 2005 by Dr Carlo Kopp

Reports indicating that the Russian Lyulka/Rybinsk Al-41F supersonic cruise engine is entering Low Rate Initial Production, and the recent Defense Acquisition Board decision to transition the supercruising F-22A Raptor to full rate production, illustrate the highly competitive nature of the fighter business. Supersonic cruise will change many aspects of how air superiority is won, and the future question in assessing fighters will inevitably be 'does it have supercruise?'
В ситуации когда русский двигатель ал-41ф Люлька поставлен на предсерийное производство в Рыбинске а также недавнее решение Совета по обороне( разгоаор об юсе)к началу серийного производства F-22A Raptor, отображает на сколько серьезна гонка в области истребителей. Сверхзвуковые крейсерские режимы поменяют тактику заваевания превосходства в воздухе, и поставят вопрос о налиичии у истребителя этих возможностей как необходимых.

Вобщем ничего нового для нас в этих обзорах нет, даю их как ознакомление с мнениием супастата о ситуации.

Achieving genuine supersonic cruise capability hinges on two technological prerequisites. The first is having a powerplant which develops enough dry thrust at altitude to offset supersonic airframe drag. The second is having an airframe design built for low supersonic drag. Unless both conditions are met, supersonic cruise capability is not achievable.


A turbofan engine designed for supersonic cruise will be characterised by a much higher turbine inlet temperature than contemporary 'conventional' fighter engines. It is this operating cycle which permits the engine to sustain higher dry thrust ratings at high altitudes. This has also proven to be the primary obstacle to date in building supercruise engines, as it requires advanced materials and advanced turbine cooling techniques.

The first service to recognise the importance of supercruise was the US Air Force, which incorporated supercruise into the early requirements definition of the Advanced Tactical Fighter (ATF) program, which eventually coalesced into today's F/A-22A Raptor. An extensive and expensive engine technology research and development effort led to the design of the Pratt and Whitney F119-PW-100 engine which powers the F-22A. Delivering around 35,000 lbf of afterburning thrust, the F119-PW-100 is the most powerful fighter engine manufactured in the Western world. The simplest qualitative measure of the F119-PW-100's performance is that this engine has a dry thrust performance envelope matching the afterburning thrust envelope of the F100-PW-100 series engines fitted to the F-15C/E and many F-16 variants

The Soviets recognised the threat presented by the emerging ATF with its supercruise capability and initiated the development of a fifth generation supercruise engine in 1985. The program was awarded to the Lyulka bureau, under the leadership of Viktor Mikhailovich Chepkin. The designation Al-41F or Izdyeliye (Article) 20 was adopted.

The first flight testing of prototypes was performed at the Gromov Institute in 1990, using a Tu-16LL Badger testbed. Subsequently a MiG-25PD was retrofitted with one of its R-15-300 engines replaced with a Al-41F prototype. Over the subsequent years thirty test flights were performed, before funding constraints slowed the effort down.

Development tests demonstrated static afterburning thrust performance claimed to be at 39,600 lbf (176 kN) with 45,000 lbf (200 kN) a design target. These figures exceed cited thrust ratings for the US F119 and F135 family engines.
