Russia's Sukhoi to develop 5th generation fighter jet
The new fighter jet will be a fundamentally new machine, not just a modernized version of an old pursuit plane
The competition of world's biggest superpowers to develop the fifth generation of pursuit planes still continues. Russian specialists intend to build
such a jet, or an aviation complex, as engineers say, in five or seven years. Technical details of such developments are being kept top secret,
although Russian aircraft designers decided to expose several solutions of theirs.
Russia's world-famous major aircraft corporations, MiG and Sukhoi were fighting for the right to take the state order for the development of the
fighter jet of the fifth generation. MiG specialists chose the 1.44 index aircraft as the prototype of the new jet, whereas Sukhoi decided to base its
work on the Su-47 fighter jet. The two planes proved excellent flight performance, but Sukhoi's Su-47 eventually won the contest.
Su-47 "Berkut" ("Golden Eagle") plane is over 25 meters long; the jet's wingspan is more than 15 meters. The peculiar feature of the Su-47 jet is
its forward swept wings, which actually gave him the "Berkut" title. The engine of the plane is another peculiarity of the machine - the engine
possesses the controlled traction vector. The traction can be changed not only on the axe of the engine, but at an angle to it as well.
The engine of the Russian company Lulka-Saturn is a unique development of Russian engineers, which does not have any analogues in the world. The
engine was originally installed on the Su-27 jet, but was subsequently modified for Su-47.
The Su-47 plane will serve as a base, on which new solutions of the fifth generation plane will be tested. Mikhail Pogosyan, Sukhoi's general
director, says that the new fighter jet will be a fundamentally new machine, not just a modernized version of the "Berkut."
The pursuit aviation has reached the point, at which the speed requires the absolute precision and attention from a pilot, who hardly has any time to
process all the information. Sukhoi specialists think that there is no point to increase the speed further on. "We do not plan the development of
aviation technology on the continuing increase of the flight speed. The absence of the future speed perfection will be compensated with a complex of
plane equipment and missiles. The ultrasonic speed capacity of the missiles will enable the destruction of even remote targets," Mikhail Pogosyan
The controlled traction vector engine of Su-47 will have to be thoroughly modernized. The aerodynamic scheme of Su-47 will undergo fundamental changes
as well. Sukhoi's specialists are currently considering an opportunity to use forward swept wings and the front horizontal empennage for the new
plane - small wings in the front part of the hull. Mikhail Pogosyan emphasized that the aerodynamic scheme would not repeat the previously discovered
solutions: it will be much more complicated.
The 5th generation fighter jet by Sukhoi will be a single-seated aircraft, in which a pilot will have an opportunity to be in full control of the
machine with the help of the high-tech equipment.
can anyone plese tell me
1 what are the criterions for a fighter to be called a 5th gen fighter ?
2 which exsisting Fighters belong to the 5th gen?
3 what are the criterions for 4.5 gen....which fighters belong to this group?
