| The Su-37 is a super-maneuverable thrust vectoring russian fighter derived from an Su-35 prototype. This demo shows the pilot literally throwing 20 tons of military metal in the sky. Two Lyulka AL-37FU vectored-thrust afterburning turbofans (30855 lb thrust each) give this aircraft it's extreme flight caracteristics that are above the flight envelope of almost any fighters curently in service in the world. The AL-37FU engines are configured for thrust vector control, with the axisymmetric steerable thrust vector control nozzle is fixed on a circular turning unit. The steel nozzle in the experimental engines is replaced in production engines by titanium units to reduce the weight of the nozzle. The nozzle only moves in the pitch axis, and the nozzles on the two engines can deflect together or differentially to achieve the desired thrust vector for a particular maneuver. The Su-37 has a variety of other innovative equipment such as a radar configured for simultaneous surveillance of airspace and the ground and a high-precision laser-inertial/satellite navigation system. The all-weather digital multi-mode phased array radar operates in either air and ground surveillance modes or in both modes simultaneously. Ground surveillance modes include mapping (with Doppler beam sharpening), search-and-track of moving targets, synthetic aperature radar and terrain avoidance. The Su-37 is also equipped with a rearward facing radar in the tail stinger area of the fuselage. The Su-37 ... |
