Lately, the Su 47 fighter jet is claimed to be similar to the technology in science fiction novels. It is as reported by Forty Five that the Russian Su-47 stealth fighter jet looks like something out of a 1960s science fiction novel but is actually technology from the mid-1980s.
Although innovative, the Su-47 prototype failed to be mass-produced due to lack of funding, and partly a less than perfect design.
Furthermore, the Su-47 has the sophistication to be able to maneuver. Due to its unstable design, the Su-47 uses a fly-by-wire system that adapts to all circumstances.
In addition, the Su-47 is also able to keep the aircraft stable during flight. It is capable of some pretty extreme maneuvers.
Some time ago, when the Soviet Union introduced the fourth generation Su-27 and MiG-29 jets against the American F-15 and F-16, the Soviet Union thought of developing a fifth generation fighter to defeat the United States.
The Advanced Tactical Fighter program that would eventually spawn the F-22 Raptor.
The Sukhoi design, which was at various times called the S-22, Su-27KM, S-37 and finally the Su-47, also featured a second set of small wings next to the cockpit which further increased maneuverability.
Together, the forward-swept wings, and horizontal tail stabilizers give it a "tri-plane" configuration. Apart from these new elements, the S-37 retains the fuselage and twin-tail configuration of the Su-27 Flanker, albeit with an unequally elongated tail boom carrying a rear-facing radar and breaker-chute.
The design of the Su-47 emphasizes quite extreme agility. The demonstrator jet made its first flight on September 25, 1997, piloted by Igor Kozintsev and two years later appearing at the Moscow air show.
The S-37 reappeared in 2001, 2003 and 2005, where it demonstrated its incredible maneuverability. The Golden Eagle is capable of reaching extreme angles of attack. But this agility masks the fact that, like the Boeing X-29, even the fiber-composite wings are severely stressed during high-speed maneuvers.
Worse, the resulting stress cracking requires replacement of the entire composite component rather than on-site repair
Combined with the heavy weapons to be added to the 18-ton jet, the Su-47 will likely be confined to a limited G load to avoid overstressing its wings and prove very expensive to maintain.
In the end, the Su-47 was never more than a demonstration of personally developed technology that ultimately demonstrated that the forward-swept wing was an idea whose time had not yet come.
In contrast, Russian fighters such as the Su-35S multi-role fighter and the Su-57 stealth jet rely on thrust vector control turbofans, which can tilt the exhaust nozzles, to achieve super maneuverability.
In fact, it was this fighter jet that is said to have pioneered some of the technologies that eventually found its way into the production of the Su-57.
