Which Sukhoi? The SU-35 Platform

As one of our readers noted, DID’s articles from 2005-2007 seem to describe 2 different SU-35s. One was a mid-life modernized SU-27 Flanker, but there’s also a much more re-engineered “SU-35″ variant with canards, thrust vectoring, etc. which has been confused with (and possibly redesignated between) the SU-37. So… what do we mean by “SU-35″?

Until very recently, only KnAAPO had listed the SU-35 as a product on its site; Sukhoi now does so as well, but Irkut does not. If this seems confusing, it’s because Sukhoi subcontracts production to affiliate firms – IAIA (Irkut) and KnAAPO (Komsomolosk un Amur). Each has their own intellectual property, and their own interests. In addition, the designation “SU-35″ has been used in several different contexts over the years. It has been referred to, and even photographed, in ways that referred to both mid-life Flanker upgrades, and canard-equipped next-generation aircraft. KnAAPO’s site added the confusion by showing SU-35 pictures on its type page and gallery that display the aircraft both with and without canard foreplanes.

The current “SU-35″, which has been definitively described by Sukhoi, appears to be something of a compromise between the upgrade and full redesign visions. Reader assistance, and sources from Sukhoi and various media, offer an outline of its key systems and characteristics.
SU-35, 2008

“…(known as Su-35BM by some sources- ie. T-10BM to the original Su-27s internal T-10S designation). Differences and features largely speak for themselves in the video, but a short summary follows as related in various other sources follows:

1 – N035 Irbis-E PESA (Passive Electronically Scanned Array) Radar, a follow-on to the Bars-M.
2 – No canards
3 – Rear-looking self-defense radar in shorter tail sting
4 – AL-37FU/ 117S thrust-vectoring turbofan engines rated at 142-147kN
5 – Extended high-lift devices with large flaperon occupying the full trailing edge of the wing
6 – L175M Khibiny-M electronic-warfare self-defense system
7 – Reduced-area empennage
8 – Larger Air Intakes
9 – New and lighter systems, including quadruple digital fly-by-wire flight-control system.
10- New man-machine interface with fully-glass cockpit with two large LCD screens and helmet mounted display.”

Sukhoi says that the fighter’s structures have been reinforced because of the increased takeoff and landing weight of the aircraft, and the front bearing has 2 wheels for the same reason. Performance is touted as 1,400 km/h (Mach 1.14) at sea-level, and 2,400 km/h (Mach 2.26) at altitude, with a ceiling up to 10 km/ 60,000 feet. Sukhoi has not touted loaded supercruise (Mach 1+, with weapons and without afterburners), which is likely to require improved engines. Thrust vectoring adds new dimensions of maneuverability, however, once pilots understand when to use it and when to avoid it.

The SU-35S will also depend on its sensors. It couples an electronically-scanned array radar with a 2-step electro-hydraulic drive unit, which creates a maximum radar beam deflection angle of 120 degrees. The NIIP Tikhomirov Irbis-E passive phased-array can reportedly detect and tracks up to 30 air targets, simultaneously engaging up to 8. It can also reportedly detect, choose and track up to 4 ground targets, and engage 2. Detection ranges of over 400 km/ 240 miles have been reported for airborne targets, which are the easiest, but resolutions are unspecified. Detecting a 747 passenger jet at 400 km is much easier than detecting a JAS-39 Gripen lightweight fighter, and information about the radar’s resolution would be needed before its real capabilities would be clear.

Full stealth jets like the F-22A Raptor, of course, create drastic reductions in radar detection range that make them a special case. In an emerging age of stealth fighters, therefore, the 80+ km detection range of the SU-35S’ IRST (infra-red search and track) system is very significant.

The SU-30 family has never been especially stealthy, and their overall airframe design limits what one can accomplish in this area. Nevertheless, Sukhoi cites an unspecified amount of “reduced reflectance” for the SU-35 in the X-band, which is a popular choice for modern radars, and in the angle range of plus or minus 60 degrees. Further improvements were made during testing by adding radar-absorbent materials, and removing or modifying protruding sensors that create radar reflection points.

The reported service life of the new aircraft is 6,000 flight hours, with a planned operational life of 30 years. The claimed service life of NPO Saturn 117S thrust-vectoring engines is 4,000 hours. Time will tell.
Russia?s SU-35 Super-Flanker: Mystery Fighter No More
 
I agree, a lot of skill and experience shown there.

The average Russian air force pilot may only fly 125 hours a year. But unrestricted airshow routines, no hard deck, no flightline setbacks from the crowds result in impressive displays.

With sequestration and no Blue Angels or Thunderbirds, this year, perhaps US airshows should get the Russian Knights and Russian Swifts with the SU-35.

Aside: story below on the Russian Swifts:

Aerobatics Ace Suspected of Badge Sales

Two reserve pilots from the Russian aerobatic team The Swifts stepped down following a recent scandal that cost their commander's job, a source in the group told RIA Novosti on Thursday.

One of the pilots resigned in protest of the commander’s discharge, which followed extortion allegations, the source said, while the other quit because the pilots were recently given odd jobs such as guard duty.

No official comment on the matter was available as of Thursday afternoon.

The Swifts were hit by a scandal last month after police accused Lt. Colonel Valery Morozov, the team's leader, of extorting a combined 35,000 rubles ($1,100) from seven of his subordinates looking to skip duty, as well as a similar sum from a businessman peddling authorized Swifts merchandize.

Morozov, who denied the allegations, was fired earlier in September. The investigation against him is still in progress.

The Swifts, along with another famous aerobatics team, The Russian Knights, were reassigned to a training center in Lipetsk region earlier this year.

The center, however, has its own aerobatics team, Russia’s Falcons, and is not interested in helping its rivals, unidentified members of The Swifts claimed in July in an interview to Moskovsky Komsomolets.

Members of the Swifts and the Russian Knights are being forced by Air Force officials to move from real fighter jets to Yak-130 jet training aircraft, the pilots said.

Moreover, two-thirds of the groups’ primary air base in Kubinka, in the Moscow Region, is currently controlled by billionaire Suleiman Kerimov, and they share it with the military. The pilots said in the interview that some of the fighter jets had to be moved out of their hangars and stationed outdoors because the military does not own the premises anymore.

The Russian Knights had to miss the prestigious airshow in the British Farnborough in July due to a lack of necessary permits from the Russian government, a scandal that many military experts called a sign of a crisis in the Russian Air Force.

Please give a little credit to the computers that actually allow that aircraft to do most of that.

Either of the aircraft make a decent match for the Hornet or the Eagle. The Raptor is even further ahead.
