It’s no secret. You can understand yourself π
Nice. What wingspan did you choose? What are the results when you do the same analysis with the official F-22 LM or USAF frontal view?
T-50 wingspan 13.95 m, F-22 front view 9.25 ΠΌ2.
Without knowing the internal layout of the aircraft, estimating “Empty weight” by comparing external dimensions is very rough at best. Your estimate about F-15 is off by 4 tons, for example. If you run same esimates for MiG-25, it would be off too.
I agree! Fighter F-15 does not fit in the statistics, the reason I do not understand.
Needless to say, the density of steel aircraft layout will differ from aircraft duralumin or titanium 290 kg/m3 vs 250 kg/m3
Have you subtracted the air intake holes from the frontal area ?

With all that is happening in the Ukraine, what a marvelous way to get the Russians on their toes and worrying…;o)
Russian are not afraid of a meteorite in Chelyabinsk … :Π
this is the Sukhoi/HAL FGFA the indian 2 seat version – looks pretty awesome!

Calculation of the Su- 33 taking off with a takeoff weight of 32,000 kg with the first / second starting position of aircraft carrier ” Kuznetsov” .
*
Taking off from the springboard is divided into four sections :
horizontal portion – 60 meters ( positions 1 and 2 ), 150 meters (position 3 )
trampoline – 45 m (radius ~ 160 meters springboard )
ballistic section 95 – 100 meters,
shallow Planning 350 – 610 meters.
*
Acceleration – 105 meters , acceleration – 4 m / s.kv , Furious, 2 x 12500 kg = 25000 kg . Resistance average ~ 6250 kg .
Takeoff time : t = kv.koren (2s / a) = kv.koren (2 * 105/4) = 7.25 sec.
Speed ββat the moment of separation : Vt = Vo + at = 0 + 4 * 7.25 = 29 m / s (104 km / h)
Impulse 32 m * 29 m / s = 928 m * m / s
After separation from the jump on the plane , the following forces , positive ( upward ) thrust of the engines of the Russian Federation * sin 14 Β° = 6 m
lift wing Cv = 1.1 ( 10% more than the Su-27 ), Y = 3.58 m (speed of 29 m / s)
*
Negative force : 32 ton weight of the aircraft ,
Negative point: 32 – (6 + 3.58) = 22.42 m / sec .
*
928 m * m / s: 22.42 m / s = 41.39 meters – the distance to the top of the hill.
Height top of the ” hills” : 22.2 m + (sin 14 degrees. * 41.39 m) = 32.2 meters above sea level .
The time of arrival in the top point ” slides ” ( distance 105 + 41.4 = 146.4 m) – 8.55 sec. , Speed ββ- 34.22 m / s (123 km / h).
*
Takeoff is considered complete when Y = m vzl . , Ie the lift of the wing will be 32,000 kg , it will happen at a speed 86.6 m / s (312 km / h) .
Accordingly, ” a shallow planning” will be: 21.65 sec (all off ) – 8.55 seconds (slide ) = 13.1 sec. Full -off distance – 937 meters, planning – 791 meters.
*
Settlement area ” planning.”
Mid- size: 60 ( deck) + 45 ( jump ) + 41.39 (slide ) + 396 m = 540 m
*
On the hill , we have the following “positive” force :
Vertical traction motors : pf * sin 14 Β° = 6 m
Lifting force of the wing (speed 43.3 m / s , Su = 1.1) – 8 tons.
” Negative ” force – aircraft weight – 32 tons
32 – 6 – 8 = 18 m / sec . Acceleration reduction 32 t / 14 t = 2.29 m / s .
*
In the middle area of planning:
Vertical traction motors – 6 tons
Lifting force of the wing ( distance 540 m , while 16.4 sec. , Speed ββ69.5 m / s ) – 20,589 tons.
” Negative ” force – aircraft weight – 32 tons , resistance Cx = 0.26 , X = 4866 kg.
a = (9.81 (P * cos a – X – F)) / G = (9.81 ( 25000 * cos 14 Β° – 4866 kg )) / 32000 = 5.94 m / s m.
The time of flight from the slides to the middle portion of planning 11.5 sec, speed – 69 m / s . The time of flight planning area – 13.5 sec. Acceleration reduction 32 t / (20,589 + 6) = -1.2 m / s .
*
Su-33 being at the height of ” hills” ( 32.2 m) begins to lose altitude at an average rate of 1.2 m / s .
During flight ” planning area “, he will lose 13.5 * 1.2 = 16.2 meters. That is, the rise will be completed at a height of 32.2 – 16.2 = 16 meters above sea level .
Based on what I venture to suggest that the Su- 33 with a maximum takeoff weight of 32 tons can surely take off from the first and second starting position at a rate headwind at least 5 – 10 m / s .
*
That is, the calculation shows that the afterburner Su-33 can fly with a maximum takeoff weight of the first and second starting position, similar can be said about the Su- 33KUB , MiG-29 and Yak -44 even . In peacetime carried off with the third starting position, apparently to compensate for the failure of one engine . At the same time the rise of the Su- 33 at maximum capacity of the engines on the basis of the calculation is not possible , even in the upper normal exit point slides will not compensate for a serious loss of height in the area of planning.

Su-27K with incomplete filling of fuel tanks, depending on the amount of suspended missiles ” air” , ranged from 25 to 28 tons while he was starting thrust 0.9-1.0 and could take off from the 1st or 2nd starting position on the deck of the ship ( the takeoff distance of 105 m ) . With full fuel tanks and maximum ammunition missiles ” air” take-off weight increased to 32 tons, and thrust was reduced to 0.8. In this case vzleet aircraft had to be made with the third starting position ( takeoff distance of 195 m ) . Hence , the aircraft could start and the maximum load it with bombs and rockets .
Despite a significant increase in landing weight , compared with the Su -27 , the introduction of a new wing mechanization and canards possible to reduce the approach speed shipborne fighter up to 240 km / h (Su- 27, usually landing with a speed of 270 km / h and only it absorbs the leveling process to 225-240 km / h , depending on the weight of the seat ) . In this case the mean free path of the Su- 27K on the deck when braking its arresting gear was to be only 90 m
Performance specifications provided Su-27K par with the most modern fighters potential enemy , and by maneuvering capabilities (angular speed bend , climb , etc.) – it is much superior to them . Significant internal fuel capacity and the availability of in-flight refueling provided Su-27K long patrols in the sky over the ocean in the area of finding ship orders , led by the aircraft carrier . Time loitering fighter armed with two medium-range missiles R -27E missiles and two melee P -73 at an altitude of 11 km and a distance of 250 km from the aircraft carrier even without refueling reached 2 hours
While in the bureau went designing the Su-27K and its building was carried out prototypes for complex ” Thread ” began a new phase of testing . In 1984 he was prepared for this prototype TI0- 25 – one of the first production Su -27 (serial Si 06-03). This machine was strengthened landing gear , arrestor hook and produced flaperons larger area . It was also changed back angle ejection seat and the setting of the system in-flight refueling . In August 1984, TI0- 25 were performed on the first aerobatsplanes taxiing and landing without alignment with the departure of the second round. I first performed in September V.G.Pugachev landing at T10 -25 arresting gear unit complex ” thread” , on the same day and made ββa similar landing N.F.Sadovnikov . Lead engineer testing T10- 25 was…
I was so comfortable. Significant difference will not : Π
In combat, fighters “Mirage-3 ‘and MiG-21SMT – equal. Both aircraft are not able to conduct long-range air combat.
In the melee, the MiG-23 is better by 18%.
