Due to the leading stealth element, the US only equips F-22 Raptor engine F-119 2D thrust vector instead of 3D. However, thanks to the transcendental aerodynamic design so 'carnivorous birds' still have amazing maneuverability. In terms of stealth capacity, F-22 Raptor impresses with extremely low radar signal feedback when only At about 0.0001 meters. Meanwhile, the Su-57 has a much larger radar signal reflection, up to 0
.5 meters at the previous hemisphere, and 0.1 meters in the remaining sides. In addition to special paint on F -22 Raptor also allows to eliminate the most radar feedback signal
Finally F-22 only uses the F-119 motor with a 2D-oriented direction instead of 3D. 2D vector thrust motor is not flexible, likely 3D, but in return them will help stealth better. F-119 motor on F-22 Raptor can only adjust the direction to up and down, instead of Can change in multiple directions like AL-41F1 on SU-57. The F-119 engine mouth is also designed with serrated cross-sections to completely reduce radar. Nanked as every ultra-mobilized combat The Russian muscle was done, the F-22 Raptor could do it. To flip the wing, the island, to lower the altitude to avoid missiles are also implemented by the F-22 Raptor. F-119 actually developed For the F-22 Raptor line with a maximum thrust of up to 156 kN, higher than 147 kN at the AL-41F1 engine is being equipped on the current Su-57 lot. . Dịch vụ:
