러시아 방송에 보도된 PAK-FA 자료 (2)...

 

1월 29일 초도비행을 실시한 이후, 러시아 방송에 소개된 PAK-FA (T-50) 스텔스 전투기 자료입니다. 러시아 방송

자료입니다만, 마침 영어로 번역된 것이 있어 함께 소개합니다.

 

앞서 소개했던 PAK-FA 자료들도 함께 링크합니다. --->

그리고 2월 12일 실시된 2차 시험비행 사진을 소개합니다. 1차 초도비행과는 달리 기체에 러시아 공군 도장을 입힌

모습입니다. 지금까지 알려진 바에 의하면, 수호이社는 모두 3대의 PAK-FA 시제기 (Prototype) 를 제작하였으며,

이중 시험비행에 이용되는 기체는 1대이며, 나머지 2대는 지상테스트 및 기타 각종 실험에 이용될 것이라 합니다.

 

 

 

Short acceleration – 200 m only – and the take-off is done! Other aircrafts can do this only from carriers. However, the Russian 5th gen fighter has a number of features allow it to take-off from a short horizontal airstrip. The 5th gen engine effectively provides it.

 

Ilia Fedorov, the Supervising Director of NPO 'Saturn', Deputy General Director of the Russian 'United Engine-building Corporation' (UEBC) tells about the difference of T-50's engine:

 

-"It has different thrust, naturally different tuning control. The number of constructive differences allow better thrust with lower fuel consumption. And the most important – it has totally different system of control".

 

The new engine of NPO 'Saturn' for PAK FA is the evolution of an engine family marked by the index '117'. Its tests on 'Saturn's facility in Rybinsk can be seen on this video. It proved its characteristics on the 1st PAK FA prototype: the taking-off is very steep on the video.

 

Sergey Chemezov, the Director General of 'Rostechnology' state corporation (NPO 'Saturn' owner) says:

 

-"The engine allowslong time supersonic fly without the afterburner. The thrust-vectoring is provided for better maneuverability".

 

The engine is the heart of a fighter, but the radar is its eyes and ears.And the navigation system is like a 'vestibular system'. All these indispensible features of 5th generation were developed together with the fighter itself.

 

Sergey Chemezov, the Director General of 'Rostechnology' state corporation (NPO 'Saturn' owner) says:

 

-"The sub-units of 'Rostechnology' Corp. are produced engines and different devices for different planes including of course– PAK FA. I think they produce about 70% in this class of parts".

 

The pilots notice with pride: even the first prototypes have almost serial avionics.They have 5 next years for elimination this 'allmost' by tests.

 

Boris Obnosov, Director General of 'Tactical Missiles Weapon' Corp., says:

 

-"The intensity of the tests had no examples even in USSR era.It due to the big numbers of devices (missiles) and shorten terms of development. As it was already declared by RuAF Commander General we are responsible to provide this plane as a weapon system".

 

It's not kind of 'demonstration aircraft' for an air-show, but the formidable universal weapon system: air-to-air, air-to-ground, short, medium and long range.R-73 – is the smallest but formidable air-to-air missiles. It's in modernization. It's a 'digital' missile like all T-50's weapon systems.

 

Boris Obnosov, Director General of 'Tactical Missiles Weapon' Corp., says:

 

-"The obligate condition for 5th gen fighters like F-22 and PAK FA as well is intra-fuselage placement of missiles. It's provided for RCS reduction".

 

The American F-22 'Raptor' was considered invincible till T-50 appearance. F-22's constructive 'ideology' is stealthiness against ground-based radars. The 'Sukhoi's fighter 'ideology': to spot 'Raptor' early and to overwhelm it in the short range fighting. In fighting stealth vs. stealth the better radar will decide the winner.

 

Vladimir Zagorodny, Constructor General, the department Chief in NIIP 'Tikhomirov' says:

 

-"We will be able to counter these stealth fighters and even win them in some duel situations".

 

Vladimir Zagorodny shows his team 'baby': the radar for the new fighter. Due to secrecy the door here is usually closed for press, but they did exception for us. The AESA has more then 1500 MMICs. This radar is named AFAR in Russian: the active phased antenna array. Five AESA radars over all airframe will detect the targets in any direction.

 

Vladimir Zagorodny, Constructor General, the department Chief in NIIP 'Tikhomirov' says:

 

-"I didn’t see such technology in 'Raptor' or F-35".

 

All T-50's electronics is netted in a unified intellectual complex, able to prompt pilot what to do in the fly. Indeed, the 5th gen fighter – is sometimes called 'flying computer'.The part of the pilot work will be done by the computer.

 

Andrey Tyulin, Director General of 'Aviapriborostroyenie' concern, says:

 

-"The avionics allow high precision flying to the needed point, successful using high precision weapon, and aircraft precise positioning in the air space".

 

Stealth technology means less IR emission and less metal in the airframe. Then, the engine blades must be hidden and the composites must be used broader.

 

Nikolay Vymornov, the Chief Technologist of NPK 'Composite' says:

 

-"In F-22 and F-35 the use of composites in airframe is not less, then 40%. We are sure, in our PAK FA fighter the use of composites will not fall of this number".

 

The new carbon-plastic composite was already developed specially for 5th gen fighters. The metal details are made with new technologies too. The plane will fly on critical and even super-critical fly regimes. So the special requirements for the materials are needed. It's OK now in Russia: our country is the biggest titan consructions supplier.

 

Sergey Chemezov, the Director General of 'Rostechnology' state corporation (NPO 'Saturn' owner) says:

 

-"The titan alloys (of T-50) are manufactured in VSMPO 'Avisma' – the world biggest titan alloys and titanproducts manufacturer".

 

The first flying prototype – is only a subject for testing. When T-50 appears in RuAF colors it probably will look rather different. However, the work done is not done in vain.
