Vladimir Putin je saopštio da će novi avion obaviti preko 2000 letnih testova pre nego se počne sa serijskom proizvodnjom. Takođe je najavio da bi sada, kada je prototip PAK FA poleteo, trebalo početi sa razvojem novog strateškog bombardera.

New Russian fighter to make 2,000 flights before production starts
01/03/201021:43

Russia's fifth-generation jet fighter, the T-50, is to undergo more than 2,000 flight tests before full-scale production starts, Prime Minister Vladimir Putin said Monday.

"Before the jet goes into production, it should complete over 2,000 test flights," Putin said.

He also said now that Russia had a fifth-generation prototype fighter, it should start working on a new-generation long-range strategic bomber that he described as "an airborne missile-carrier."

A source at the Sukhoi aircraft maker said earlier in the day the T-50 would start on a standard flight test program in April, adding it would take "several years" to complete the testing program.

A prototype of the fighter made a 47-minute maiden flight in Russia's Far East on January 29.

Russia has been developing its newest fighter since the 1990s. The current prototype was designed by the Sukhoi design bureau and built at a plant in Komsomolsk-on-Amur, in Russia's Far East.

It will be delivered to the Russian Air Force from 2015 onwards.

Russian officials have already hailed the fighter as "a unique warplane" that combines the capabilities of an air superiority fighter and attack aircraft.

The Tupolev aircraft maker said last year that a new-generation strategic bomber would be developed by 2017, while production should start in 2020 to 2025.

However, Maj. Gen. Anatoly Zhikharev, commander of Russia's strategic aviation said a new strategic bomber, which would use stealth technology, was expected to enter service in 2025-2030.

The new bomber will replace three aircraft currently in service with Russia's strategic aviation, the Tu-95MC Bear and Tu-160 Blackjack strategic bombers, introduced in 1956 and 1980, respectively, and Tu-22M3 Backfire long-range bombers, which first flew in 1972.

Koliko je ova 35-tica lepsa od PAK-a.

[zixo]

Jeste ali joj je zato radarski odraz nekoliko puta veci

[pvanja]

Evo dva dobra vide nazalost samo na ruskom pa ako neko zna ruski i voljan je da ukratko napise o cemu se govori na snimcia

Photoshop je ponovo radio ali lepa slika

[dexy]

Ova slika prikazuje da se motor jasno vidi s prednje strane, pitanje je kako je rešeno sakrivanje motora?:

Dexy odlicna fotka.

Da vidi se gotovo 1/3 motora.

Malo mi je cudo to posto ako pogledas gornju sliku - ceoni profil vidis kako motori soje pod uglom u odnosu na uzduznu osu aviona. Po ovoj drugoj slici ispada da motor nije ravan vec da je zakrivljen po uzduznoj osi.

Bas uporedi ovu sliku sto si postovao gore

Steta sto je ova fotka gde se vidi kompresor slikana po mraku pa se nevide zadnji deo motora.

Barem su ga lepo ofarbali

[Bandzi]

Moguće da su to nepokretne lopatice pre kompresora, radi smanjenja radarskog odraza. Ovako je to na F-18E/F

[zixo]

Meni nije logicno da se ovoliko vidi motor, ako gledamo one projekcije. Motor i uvodnik nisu u istoj ravni. Pitanje je da li su crtezi onda tacni.

[pvanja]

Interesanto resenje, samo me interesuje kolik umanje efikasnos motora u stelt rezimu

[dexy]

Negde sam naleteo na informaciju da ovaj sistem može da se koristi samo u podzvučnom režimu, ako je tako to je onda velika mana u odnosu na F-22 koji zadržava radarske stealth karakteristike i pri nadzvučnom krstarenju.

Evo par slicica kako su drugi reslili problem skrivanja motora od radara.
