He he, YF-22 vs YF-23 Samo kod Rusa onog drugog zatuku necim u glavu i zakopaju u Sibiru da ne komplikuju puno...

Aman neki pukli pa im krivo. Ali bi sigurno svi voleli da vide projekat.
flateric ::seems that the same MiG guys have reached Mr.Rogozin recently
there was also PAK FA alternative developed at Sukhoi in 2005 that was thrown off in favor of Davidenko's T-50
in summer of 2010 its author together with 'alternative T-50 mafia' have tried to push it again through Zhirinovsky that reportedly had forwarded their letter to Medvedev
they blamed existing T-50 as big mistake having structural problems due to rear weapons bay placement and downgraded specifications compared to Raptor and alternative PAK FA
last project, they say, has 'right aerodynamics' and abilities compared to Boeing's NGAD/F-X

A Rogozin tupi kako bi trebali imati alternativu i podstakli konkurenciju. E pa kasno ste se setili. To je trebalo uporedo ako hocete "konkurenciju"

Ništa novo, samo jedan mali dodatni podatak da je brži (sa forsažom i brez forsaža) od F-22 i J-20

Nego mene zanima koliki bi bio plafon leta Su-XX ako za F-22 kažu da je 22 000m? Šta sve utiče na max. visinu?

Taj inace ruski podatak o plafonu leta za F-22 od 22000m ( pitanje je i kojem prakticnom tj.operativnom ili dinamickom ) treba uzeti sa rezervom .Na netu se najcesce srece podatak o 19800m.
Jaka pogonoska grupa ali i odnos potisak/masa su od presudnog znacaja za plafon leta.Vec sam pomenuo jednom prilikom kako smo mogli da vidimo iskakanje venecuelanskih Su-30MK na 22 ili 23 km nebitno .
Naravno lovci sa turbomlaznim pogonom imaju prednost ( MiG-25 ) kada je operativni plafon u pitanju .

Ja bi jos samo dodao da su "wing loadnig" i karakteristike motora, odnosno procenat gubitka snage na velikim visinama vrlo bitni. Takodje dolazi do fenomena koji se nazivaju "shock stall - mach bufet" i "coffin corner" koji zavise od uzgonskih svojstava krila.

Takodje mogu da postoje restrikcije vezane za kompresiju kabine i optimalnu visinu sa koje avion moze bezbedno da se spusti na nize visine u slucaju dekompresije.

New Delhi: The Indo-Russian fifth generation fighter aircraft (FGFA) is superior than the similar Chinese and American rival fighter jets which include the J 20 Black Eagle and the F-22 Raptor, a top Russian military commander claimed.

India and Russia are jointly developing the Sukhoi T-50 PAK FA FGFA for their respective air forces and have plans of producing over 400 of these highly-advanced fighter jets.

Commander of the Russian Air Force Colonel General Alexander Zelin told Russian news agency RIA Novosti that his country’s government has decided to give top priority to the development of the joint venture aircraft.

“While comparing Russia’s T-50 PAK FA with the US F-22 Raptor and China’s Chengdu J-20 Black Eagle, one concludes that the T-50 is superior to its foreign analogues in terms of its maximum speed in afterburner and standard modes, maximum range and thrust-to-weight ratio,” he said.

The Russian Air Force Commander said that despite the comparable dimensions and weight of the Chinese J20 Black Eagle and the F-22 raptor, “the T-50 has much shorter take-off and landing runs. Moreover, its on-board equipment has better specifications than its foreign equivalents”.

India signed a preliminary design contract with Russia recently for the aircraft and is planning to induct around 250 of them starting from 2017.

Commenting on the flight tests schedule of the FGFA, Zelin said, “Tests are now taking place as planned in line with specific decisions.Over 100 flights have been performed and all the specifications obtained during the tests confirm T-50 project requirements.”

“The tests involve three fixed-wing aircraft, and three more aircraft will arrive in the near future. All in all, the tests will involve 14 aircraft,” he added.

In another development, the Russian nuclear-powered attack submarine, K-152 Nerpa, will reach India on 30-31 March, an Indian defence ministry official said.

“We expect the submarine to arrive in India on March 30-31,” the official told Ria Novosti. The submarine, which has been leased to India, is on way to Visakhapatnam, the official said.

The delivery of the submarine which was scheduled to be in 2008 got delayed after 20 people lost their lives due to gas leakage during sea trials.
