Su-27SK (flight manual)
27380 kg – 9220 kg (fuel) – 726 kg (2R27+2R73) – 100 kg (pilot) – 58 kg (shells) = 17276 kg
23250 kg – 5090 kg (fuel) – 726 kg (2R27+2R73) – 100 kg (pilot) – 58 kg (shells) = 17276 kg

not taken into account the links of the tape GSH-301

– Su-35 weights 3 tons more than Su-27? Why?

Su-35S, the volume of electronic equipment has decreased. Its density if I am not mistaken 320 kg/m3. In its place filled with fuel density of 800 kg/m3. Heavier nozzles and engines with increased resource, they are also heavier. Reinforced wing, now there can be suspended external fuel tanks 2 x 2000 liters. This required strengthening the structure, logically.

Su-57. The selected angles for the nose cone and air intakes clearly indicate a maximum speed of at least M=2.35 (2500 km/h) The selected angle of the leading edge of the wing implies a high cruising speed, probably M=1.78 (1890 km/h)

Volume X-47B – 49.5 m3. Take-off weight of 20215 kg. the density of the arrangement 20215 kg : 49.5 m3 = 408 kg/m3 Volume S-70 – 59.2 m3 * 408 kg/m3 = 24176 kg

MiG-29 – 15000 $/hour for Russian air force 35000 $/hour for foreign customer
MiG-29SMT – 9000 $/hour
MiG-35 – 7500 $/hour
Su-27 – 20000 $/hour
Su-35S 11000 – 12000 $/hour
F-22 – 68362 $/hour
F-35 – 35200 $/hour

Thanks Paralay, does the table come from a book? Do you have the reference?

Its maximum speed is limited
Damaged wings cannot be repaired
