<SPAN class=mw-headline>Development</SPAN></H2>
<P>Originally known as the S-37, Sukhoi redesignated its advanced test aircraft
as the Su-47 in 2002. Officially nicknamed <I><B>Berkut</B></I> (Golden Eagle),
the Su-47 was originally built as Russia's principal testbed for composite
materials and sophisticated fly-by-wire control systems. The aircraft makes use
of forward-swept wings allowing superb maneuverability and operation at angles
of attack up to 45° or more.</P>
<P><A title=TsAGI href="http://en.wikipedia.org/wiki/TsAGI">TsAGI</A> has long
been aware of the advantages of forward-swept wings, with research including the
development of the <A class=new title="Tsibin LL (page does not exist)"
href="http://en.wikipedia.org/w/index.php?title=Tsibin_LL&action=edit&redlink=1">Tsibin
LL</A> and study of the captured <A title="Junkers Ju 287"
href="http://en.wikipedia.org/wiki/Junkers_Ju_287">Junkers Ju 287</A> in the
1940s. Forward-swept wings yield a higher maximum lift coefficient, reduced
bending moments, and delayed stall when compared to more traditional wing
shapes. At high angles of attack, the wing tips remain unstalled allowing the
aircraft to retain aileron control. Unfortunately, forward sweep also induces
twisting (divergence) strong enough to rip the wings off an aircraft built of
conventional materials. Only recently have <A class=mw-redirect
title="Composite materials"
href="http://en.wikipedia.org/wiki/Composite_materials">composite materials</A>
made the design of aircraft with forward-swept wings feasible.</P>
<P>Like its US counterpart, the <A title="Grumman X-29"
href="http://en.wikipedia.org/wiki/Grumman_X-29">Grumman X-29</A>, the Su-47 is
primarily a technology demonstrator, one intended to lay the foundation for the
next Russian fighter. Such a fighter must not only be as advanced as the US <A
title="F-22 Raptor" href="http://en.wikipedia.org/wiki/F-22_Raptor">F-22
Raptor</A>, but must also compete for funding with the more conventional <A
title="Mikoyan Project 1.44"
href="http://en.wikipedia.org/wiki/Mikoyan_Project_1.44">MiG 1.44</A>. However,
Sukhoi is now attempting to market the Su-47 to the Russian military and foreign
customers as a production fighter in its own right.<SUP

<P>The Su-47 is of similar dimensions to previous large Sukhoi fighters, such as
the <A class=mw-redirect title=Su-35
href="http://en.wikipedia.org/wiki/Su-35">Su-35</A>. To reduce development
costs, the Su-47 borrowed the forward fuselage, vertical tails, and landing gear
of the <A title="Sukhoi Su-27"
href="http://en.wikipedia.org/wiki/Sukhoi_Su-27">Su-27</A> family. Nonetheless,
the aircraft includes reduced radar signature features (including radar
absorbent materials),<SUP class="noprint Template-Fact"><SPAN

advanced radar. Though similar in overall concept to the American <A
title="Grumman X-29" href="http://en.wikipedia.org/wiki/Grumman_X-29">X-29</A>
research aircraft of the 1980s, the Su-47 is about twice the size and far closer
to an actual combat aircraft than the US design.</P>
<P>To solve the problem of wing-twisting, the Su-47 makes use of composite
materials carefully tailored to resist twisting while still allowing the wing to
bend for improved aerodynamic behavior. Due to its comparatively large wingspan,
the Su-47 is to be equipped with folding wings, in order to fit inside Russian
hangars. Like its immediate predecessor, the <A class=mw-redirect title=Su-37
href="http://en.wikipedia.org/wiki/Su-37">Su-37</A>, the Su-47 is of tandem-<A

with <A title="Canard (aeronautics)"
href="http://en.wikipedia.org/wiki/Canard_(aeronautics)">canards</A> ahead of
wings and tailplanes. Interestingly, the Su-47 has two tailbooms of unequal
length outboard of the exhaust nozzles. The shorter boom, on the left-hand side,
houses rear-facing <A title=Radar

<P>The Su-47 has extremely high agility at subsonic speeds, enabling the
aircraft to alter its angle of attack and its flight path very quickly while
retaining maneuverability in supersonic flight. The Su-47 has a maximum speed of
Mach 2.34 at high altitudes and a greater than 9g capability.<A
class="external autonumber"

href="http://www.airforce-technology.com/projects/s37/" rel=nofollow>[1]</A></P>
<P>Maximum turn rates, and the upper and lower limits on airspeed for weapon
launch, are important criteria in terms of combat superiority. The Su-47
aircraft has very high levels of maneuverability with maintained stability and
controllability at extreme angles of attack. Maximum turn rates are important in
close combat and also at medium and long range, when the mission may involve
engaging consecutive targets in different sectors of the airspace. A high turn
rate of the Su-47 allows the pilot to turn the fighter aircraft quickly towards
the next target to initiate the weapon launch.</P>
<P>The swept-forward wing, compared to a swept-back wing of the same area,
provides a number of advantages:</P>
<UL>
<LI>higher lift-to-drag ratio
<LI>higher capacity in dogfight maneuvers
<LI>higher range at subsonic speed

<P>The Su-47s fuselage is oval in cross section and the airframe is constructed
mainly of aluminium and titanium alloys and 13% (by weight) of composite
materials. The nose radome is slightly flattened at the fore section, and has a
horizontal edge to optimise the aircraft's anti-spin characteristics.</P>

<SPAN class=mw-headline>Wings</SPAN></H3>
<P>The forward-swept midwing gives the unconventional (and characteristic)
appearance of the Su-47, earning it the nickname of 'devil' and 'slingshot'. A
substantial part of the lift generated by the forward-swept wing occurs at the
inner portion of the wingspan. The lift is not restricted by wingtip stall. The
ailerons - the wing's control surfaces - remain effective at the highest angles
of attack, and controllability of the aircraft is retained even in the event of
airflow separating from the remainder of the wings' surface.</P>
<P>The wing panels are constructed of nearly 90% composites. The forward-swept
midwing has a high aspect ratio, which contributes to long-range performance.
The leading-edge root extensions blend smoothly to the wing panels, which are
fitted with deflectable slats on the leading edge; flaps and ailerons on the
trailing edge. The all-moving and small-area trapezoidal canards are connected
to the leading-edge root extensions.</P>
<P>The downside of such a wing design is that it produces strong rotational
forces that try to twist the wings off, especially at high speeds. This twisting
necessitates the use of a large amount of composites in order to increase the
strength and durability of the wing. Despite this, the plane was initially
limited to Mach 1.6. Recent engineering modifications have raised this limit,
but the new limit has not been specified.</P>

<P>Although not revolutionary, the <A title="Thrust vectoring"
href="http://en.wikipedia.org/wiki/Thrust_vectoring">thrust vectoring</A> (with
PFU engine modification) of ±20° at 30°/second in pitch and yaw will greatly

<SPAN class=mw-headline>Cockpit</SPAN></H3>
<P>The cockpit's design has focused on maintaining a high degree of comfort for
the pilot and also on the pilot being able to control the aircraft in extremely
high <I>g</I>-load manoeuvres. The aircraft is equipped with a new <A
title="Ejection seat" href="http://en.wikipedia.org/wiki/Ejection_seat">ejection
seat</A> and <A title="Life support (aviation)"
href="http://en.wikipedia.org/wiki/Life_support_(aviation)">life support
system</A>. The variable geometry adaptive ejection seat is inclined at an angle
of 60°, which reduces the impact of high <A title=G-force
href="http://en.wikipedia.org/wiki/G-force"><I>g</I> forces</A> on the pilot.
The seat allows dogfight and missile avoidance maneuvers with significantly
higher <I>g</I> loadings than can normally be tolerable. The Su-47 pilot uses a
side-mounted, low-travel control stick and a tensiometric throttle control. This
reclined seating arrangement was first used in the <A
