Named Berkut, which translates to mean Golden Eagle or Royal Eagle, the S-37 bears an "S" rather than an "Su" designation because it is an experimental rather than production aircraft.
It has a length of 74 ft. and a wingspan of 54 ft. 10 in., with a maximum takeoff weight of just under 75,000 pounds. Power comes from two Aviadvigatel (Perm) D-30F6 turbofans, each developing 34,177 pounds of static thrust with afterburners—but without a thrust-vector ring. Together the engines give the S-37 a respectable, if unspectacular, top speed of around Mach 1.6. The aircraft may be re-engined with Sukhoi's preferred option of two Lyulka (Saturn) AL-41F turbofans with thrust vectoring, when these formidable engines—which pour out 39,350 pounds of static thrust with afterburners—become available.
The real innovations in the S-37 lie within its unconventional design. The swept-forward wing is part of a so-called "tandem triplane" arrangement, blending all-moving forward canards with the swept-forward wing, a short-span broad-chord swept horizontal tail plus outward-canted vertical tailplanes.
Much of the S-37 program remains veiled in secrecy, but its potentially world-beating design truly extends the boundaries of state-of-the-art fighter technology.
Russia’s fabled Sukhoi Design Bureau builds the S-37, a 21st century fighter to go head-to- head with our F-22, although I dont know to what extent we can actually campare the two being that the F-22 has true stealth design and charasteristics !!!
