Loved it a long time ago but anymore it just seems outdated. :(

[Sua_Sponte]

Interesting aircraft, doubt it will go into full production if it hasnt already though. the US fooled around with that wing configuration in the late 80s and early 90s, and never bought into it for whatever reason.

btw nice toy....

[Hullebullen]

So what's the deal with forward-swept wings? Tighter turns? Overall better manouverability? Or just because it looks cool? p-)

because it's VERY unstable if I remember right. of course this may just be a test bed for future airframes and not a production prototype.

again becasue it's unstable, and the best fighters are unstable ones...likely why it has canards in front. does anyone know if it has FBW installed?

SU-47 (S-37) BERKUT EXPERIMENTAL FIGHTER AIRCRAFT, RUSSIA (http://www.airforce-technology.com/projects/s37/)

snip...

The Sukhoi Design Bureau of Moscow, Russia has developed the Su-47 (previously called the S-37 Berkut or Golden Eagle) fighter aircraft, which first flew in September 1997. Su-47 is in a forward swept wing configuration and uses a highly unstable triplane (with three main lifting surfaces) aerodynamic configuration. The Su-47 completed the first stage of flight trials in December 2001. In May 2002, Sukhoi was selected as prime contractor for the next-generation Russian PAK FA fighter programme. The PAK FA will be a development of the Su-47 but without the forward swept wings.

The design of the very high manoeuvrability prototype is based on the avionics and aerodynamics technologies developed for the Su-27 upgrade programme. Some of the systems and component designs from the Su-27, (the all weather supersonic fighter aircraft with NATO reporting name Flanker), have been used in the Su-47, for example the design of the canopy, landing gear, some of the avionics and the near-vertical tails.

MANOEUVRABILITY

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, and it also retains manoeuvrability in supersonic flight.

Maximum turn rates and the upper and lower limits on air speed for weapon launch are important criteria in terms of combat superiority. The Su-47 aircraft has very high levels of manoeuvrability with maintained stability and controllability at all 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.

The swept-forward wing, compared to a swept-back wing of the same area, provides a number of advantages: higher lift to drag ratio; higher capacity in dogfight manoeuvres; higher range at subsonic speed; improved stall resistance and anti-spin characteristics; improved stability at high angles of attack; a lower minimum flight speed; and a shorter take-off and landing distance.

Uber cool look but too bad thats not enough in todays world.


On another note. If they ever did a top gun 2 this would be the perfect badguy fighter.

"Highway to the dangerzone..."

:D :D

It is not Su-47 it is C-37

bad ass !!!! I want one :) nice pics goldman

Nice pics. :)

The US developed something similar in the 80s.

The X-29 FSW :

It was only built as a demonstrator, but it does look awsome. p-)

Nice pics Goldman, but this was a technology demonstrator and was intended to test new technologies (design and manufacture) and to win the competition to build the next Russian fighter.


Interesting aircraft, doubt it will go into full production if it hasnt already though. the US fooled around with that wing configuration in the late 80s and early 90s, and never bought into it for whatever reason.

It was never intended to go into service. And the Russians were testing such planforms at a similar time to when the germans were... in the 30s and 40s.


So what's the deal with forward-swept wings?

A swept wing delays the onset of sonic drag. In other words it lets you go from subsonic to supersonic more easily. (Note swept wings aren't a necessity for supersonic flight but they make it easier... the X-1 and the F-104 both had straight wings for example).
The problem with swept wings is that sometimes instead of flowing straight over the wing and generating lift the air flows along the wing. Some aircraft have wing fences to stop this... the air flowing over the top of the wing more of a problem with spanwise flow than the air flowing below the wing.
With swept back wings when the air travelling along the wing goes over the tend (wingtip) it generates a huge vortex that creates drag. With forward swept wings the spanwise flow travels inwards towards the wingroot and the wing tip vortex is tiny and this greatly reduces drag.

Forward swept wings are also very good for manouverability at low airspeeds.


because it's VERY unstable if I remember right.

Stability or instability can be built into and aircraft or out of an aircraft. The F-16 is for example a very unstable aircraft.


again becasue it's unstable, and the best fighters are unstable ones...likely why it has canards in front. does anyone know if it has FBW installed?

Not necessarily. The F-15 is not unstable and has no FBW system, and I'd rate it as an excellent fighter.

The Su-47 has got a FBW system.


It is not Su-47 it is C-37

Sukhoi have labelled it Su-47.


The X-29 FSW :


The X-29 is just an F-5 fighter with from memory an F-16s engine and a FSW and canards. It was also just a technology demonstrator.


the russians captured it at its factory and took it for a test flight with its German crew

The problem with a forward swept wing is that when you turn left or right the extra speed over the advancing wing generates extra lift... which results in it rising, which increases its angle of attack... which increases lift some more... etc etc in a vicious circle... and unless you make the wings incredibly heavy and strong they get ripped off with any hard turn. That is why the Germans only prototyped bombers with FSWs. In the 80s both the Russians and the US revived the idea because new composite materials allowed them to make a wing that was rigid in one direction and flexible in another... so when you turned the wing that generated more lift didn't flex up.

With the focus on Stealth however FSW are not so great.

The only FSW aircraft I could see being worthwhile making would be a carrier based aircraft as the low speed handling and smaller lighter wing than a back swept wing would be an advantage.

[Holycrusader]

why would anyone on the side of the victors be pissed off?

You tell us :)

wowwwwww
this plane is super
thnxs for posting

awesome pics man, anyone got some pics of the cockpit????

It probably one of numerous testing and evalutaion desings...

Well, basically it was Ronald Reagan who caused it when you search for a Person. But the collapse was just a question of time.

thxs for sharing your knowledge

[NicNZ]

Come on Tel you would have to concede that the Reagan-era US accelerated the collapse of the USSR. You'd also have to concede that if one side "won" the Cold War, the US (arguably NATO) was it.


Also thanks for the pics and discussion :)

nah the west cant take all the credit for causing the fall of the soviet union - the communist were doing a pretty good job of it on their own.

[Lokos]

Sure, having to spend one third of the GDP on defence because of an arms race that an economically superior belligerent is insisting on pursuing can lead to disaster - this was definitely the case with the Soviet Union. And? In the war of throwing money at things until they go away, the United States surely does take the trophy home.

are there any videos of this aircraft?

btw:

come on Tel you would have to concede that the Reagan-era US accelerated the collapse of the USSR
actually it slowed the collapse down - if there was no thread to SU there would have been more people who would have opposed the government because of the bad conditions they lived in - but if the government can say that there is an dangerous enemy people are intimidated and accept that they have to live in this conditions for a while

its the same thing american government does today with their people ;)
