| Sukhoi Su-47 (Su-37) Berkut Supersonic Jet Fighter |
 |
The Sukhoi Su-47 Berkut (Russian: Су-47
"Беркут" - golden eagle), also
designated S-32 and S-37 during initial
development, is an experimental supersonic
jet fighter developed by Sukhoi Aviation
Corporation. The NATO reporting name for this
aircraft is "Firkin". A distinguishing
feature of the aircraft is its forward-swept
wing, similar to that of the Grumman X-29.
Although the Berkut has been referred to as
the Su-47 since 2002, suggesting that it is a
ready-for-production warplane, it will more
likely be heavily redesigned (as part of the
Prospective Air Complex for Tactical Air
Forces program) before any series production
begins. The Su-47 designation may or may not
be reused for the PAK FA design.

| Su-37 extreme manuevrability demo |
 |
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
(30,855 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
features fly-by-wire and relaxed static
instability, which along with 3D thrust
vectoring give the aircraft tremendous
agility. It incorporates state of the art ECM
in wing-tip pods, allowing improved
survivability in electronic warfare
environments. The Su-37 can carry air-to-air
and air-to-surface weapons on 12 stations.
The number of missiles and bombs carried can
be increased to 14 with the use of
multi-payload racks.
Sukhoi used payments earned in the sale of an
Su-27 license to China to finance the Su-37
development. Russia's Air Force has not
ordered any Su-37s. Sukhoi is studying the
possibility of developing a two-seat version
of the Su-37 with enhanced strike
capabilities.
