    You’re right, from an economic point of view, NATO would win. I was speakiing from the technical point of view of the ease of manufacture, ruggedness and maintainability of the WP platforms.

    Its how the Soviets won WW2 despite the lack of a vibrant economy.

    That is not the main reason for the Soviets’ victory over Nazi Germany in 1945. And what is this with this stereotype, of “the ease of manufacture, ruggedness and maintainability of the WP platforms”?

    А вместо сердца – пламенный мотор

    Отдельной темой прозвучали вопросы по авиадвигателям для новых авиационных комплексов фирмы. Вначале на них отвечал Александр Давиденко.
    – Двигатель на ПАК ФА тот же, что и на Су-35?
    – По газодинамическим характеристикам эти двигатели похожи, но весьма важный момент. Двигатель на Су-35 пришел как раз с нашего проекта, а не наоборот. Он разрабатывался для Т-50, причем настолько быстро и успешно, что его применили на Су-35, но со старой системой управления для всего семейства АЛ-31.
    Двигатель на Т-50 по сравнению со своим предшественником принципиально лучше. Он обладает элементами пятого поколения. Применена новая турбина, благодаря которой улучшены расходные характеристики. Они, может, не совсем оптимальны, но тем не менее все заданные требования мы реализуем с запасом. Существенно увеличена тяга двигателя. У него принципиально другая система управления. Она цифровая, и при создании двигателя второго этапа, скорее всего, перейдет на него один к одному. Мы уже сейчас за счет этой системы из двигателя вытащили все ресурсы по его управлению.

    It’s a source from 2010 – maybe someone has a more up-to-date source?

    Nope.. The T-50 uses Izd.117 engine which is another designation for Al-41F1, an upgraded variant of the Al-41F from the MiG 1.44 project and has an entirely new core with different high and low pressure turbines, as well as more advanced FADEC.

    You believe that 117 engine is a further development of the MiG 1.44 AL-41 (some sort of variable-bypass-ratio tech, like on the F-23 powerplant) – sure about that? pretty certain its a development of the AL-31 as is the Su-35’s ‘117’?

    And the variant that India will get will have those engines, hence the reasoning to buy the Su-35 makes absolutely no sense in this context.

    Exactly, the Su-35 wouldn’t be such an improvement upon the Su-30MKi anyway – to be honest. Isn’t there a Super 30MKI MLU on the way? Will it be refitted with the Su-35 powerplant 117S?

    No they don’t. Can this myth die already?
    And they don’t share engines either.

    You could argue the 117S is closer to AL-31FP, than it is to the new Type 30.

    The T-50 and Su-35 are both flying with essentially the same engines today. The T-50 should fly with a new engine design in the future.

    What is the purpose of this one-sided political propaganda topic?

    I’m not sure myself. I was recently in regular contact with a young lady from the central Turkish region of Dersim – I learnt a lot about the Dersim rebellion of the 1930s from her, and something about the history of the Turkish air force. The TuAF had female attack pilots in combat at that time – this woman in particular.

    The aircraft is a Breguet 19

    Thanks for linking that. I missed it, not being a regular on ModMil

    well, it was eight years ago. No harm raising the topic again if you see fit.

    Probably in Columbia over a year ago.

    A lot longer than one year ago:

    How is it Sputnik’s fault when they are quoting Debka?

    It’s their fault exactly because they quoted ‘DEBKA, perhaps?

    (Hey, don’t blame me, I’m only quoting the National Enquirer…)

    Certainly the Tiger helicopter is more or less in the same category as the Apache or Mi-28. How do the sensors on the Tiger compare with Mi-28 – what about armament fit and combat radius? The only real advantage the Mil might have is in armour protection – important maybe to the Russian military, obviously not to the French or Germans or to those other countries which have developed such 2-seat heli-gunships.

    No, the article Tango posted (and you quoted) mentioned an RPG shoot down of the Cougar helicopter on May 1st – third paragraph from the bottom.
    But here is another link confirming the RPG kill by Mexican authorities:

    edit – I see where the confusion lies. The Mexican authorities did initially describe the Cougar shootdown as a ‘forced landing’ – they pretty soon changed their story when the facts became clearer.

    On the contrary to the Cougar earlier

    Maybe it’s because the Cougar was hit by a rocket-propelled grenade (a primary killer of helicopters these days) while the blackhawk was only hit by 7 bullets – it’s written in the article given.

    So you don’t know the answer and just make rediculous statements. :rolleyes:

    Face it the T-50 is clearly well above Mach 2 design and Bondarev confirms yet. Faster than F-22 for sure, much sleeker.

    How fast is the F-22? Is it’s top speed in the public domain?

    I personally think that the T/W, wing loading or thrust figures say roughly as much about flying qualities of an aircraft as bhp, torque and weight fiugures say about sports cars. They are useful indicators but don’t provide the overall information… the true know-how is in the details, fine balancing, aerodynamics and emotional value… on the paper, the Camaro ZL1 appears every bit as good as F458 Speciale and greatly superior to Carrera GT3… nothing can be further from the truth..

    The Camaro is sold new for $56 thousand, the F458 Speciale sell for $288 thousand – and hundreds of thousands of the Chevys have been produced. I think that’s the most important contrast one should make. It’s also a comparison that has similar meaning when comparing combat aircraft – wars are fought with the hardware that’s actually available to the combatants – hardware they can pay for, or are willing to pay for.
