An-124 bailin’ NATO out yet again. :p
Oleg Antonov turns in his grave

Compare the density of aircraft company Sukhoi.
Su-27 252 kg / m³
Su-33 282 kg / m³
Su-33KUB 254 kg / m³
The Su-35 253 kg / m³
Packaging density range 252 – 282 kg / m³
The density of empty T-50 15737 – 17611 kg.
Compare the density of the layout of American planes.
F-16, the volume of 34.62 cubic meters, the aircraft empty weight 8910 kg, the density 8910 kg: 34.62 m³ = 257 kg / m³
F-15, 60.5 cubic meters, 12,975 kg empty, density 215 kg / m³
F-14, 76.5 cubic meters, 18,191 kg empty, density 238 kg / m³
F-18C, 47 cbm, empty 11,340 kg, the density of 241 kg / m³
F-18E, 49.15 cubic meters, empty 14300 kg, the density of 290 kg / m³
F-35A, 49.97 cubic meters, 13,290 kg empty, density 266 kg / m³
Thus the density of the empty American plane in the range of 215 – 290 kg / m³. Mean weight of the empty F-22 is 14,038 kg – 18,936 kg.
wikipedia states that T50 has empty weight of 18,500 kg (40,785 lb)
Su 27 empty weight is stated at 16,380 kg (36,100 lb)
Wikipedia has long been visited paralay.сom 😉
Su-27 had the empty weight 16,380 kg during the test, then the distance of the flight reached 3,900 km. Su-27 standing in the arsenal is empty weight of 17,500 kg and 3,680 km range.
Weight of the T-50 can not be greater than that of the Su-27. But the weight will be comparable if the operating load a fighter T-50 reaches 10g.
A comparison of the Su-27 / T-50:
area of a side view 38 / 27.8 square meters
area of the top view 110 / 115.6 square meters
area of the front view 10 / 9.47 square meters
volume 69.41 / 62.45 cubic meters
empty weight of the T-50: 17500 kg * (62.45: 69.41) = 15745 kg
Нет Новосибирск ни Ульяновске. Оставайтесь с нами. Более hi – reses по прибытии в UUBW
then so 🙂
Today, it is Domna
This is the first long-distance flight in the history of the PAK FA, there is no reason to risk. I think it will fly all the way to subsonic speed. Flight range of the T-50 without external fuel tanks – 3000 km.
Well , has 054 reached LII yet, or it has an overnight intermediate stop along the way? Thanks.:)
Komsomolsk-on-Amur – Domna 1700 km
Domna – Novosibirsk – 2000 km
Novosibirsk – Ulyanovsk 2,200 km (?)
Ulyanovsk – Zhukovsky – 700 km
one engine – a problem
four engines – four problems 😉
I put it wrong, let it be: aircraft with a wing of moderate sweep, can not long fly at low altitude at supersonic speed. 😉
In Su-27SK manual it says Su-27 is limited 1400 km/h at sea level with a clear statement that “its not flight mode or time limited”. (if google translator is right)
1. Maximum speed and flight Mach number:
– V = 1400 km / h Mode is not limited by time. – For strength.
– M = 2.35. For M = 2.15 – 2.35 to 5 minutes. – The canopy glazing
Of altitude there is not a single word. Minimum flight altitude of the Su-27, which is mentioned in the manual – 300 meters, when attacking ground targets.
“Range at low altitudes depends on the load on the wing, flying speed and sweep angle console. However, in the M ~ 0.8 (V ~ 1000 km / h) at a wing loading of G / S = 350 – 500 kg / sq m aircraft drag is almost independent of the position of the console, which provides a slight difference in kilometer fuel consumption when the angle sweepback. “Byushgens, page 93
That is, at speeds above M = 1 and the low-altitude flight in an aircraft with a wing sweep of moderate (~ 40 °) dramatically increases air resistance and reduced range. Long flight is not possible, because of the violent shaking.
If we compare the aerodynamic configuration and the location of the center of pressure, it appears that J-20 is closer to the S-37, not the MiG 1.42 😉
Red Line – Location of the main landing gear
Wrong. In that very case it is about buffeting which does not allow to keep supersonic speed for more than a brief moment. 😉
That’s what I believe 🙂
Not true. I’ve seen HUD tapes that say otherwise.
Show 😉
Swing wing = excellent lift characteristics for takeoff and landing from short runways or aircraft carriers (used to compensate for insufficient thrust/acceleration), can facilitate high speed flight with proper sweep, heavy, complex, expensive, failure prone.
The plane with the wing (F-111, Su-24, B-1B, Tu-22M, Tu-160) is able to fly at a height of 30 – 50 meters at supersonic speed. Other aircraft (F-15E, Su-34) no more than M = 0.85.
