Leader in Combat Aviation?

Videoconference on help to the aviation industry

On May 13, RF President Vladimir Putin conducted a videoconference from his “bunker” in Novo-Ogarevo on support to Russia’s aviation industry in the pandemic and economic crisis. He directed his ministers to shift civilian, and possibly some military, aircraft production “to the left” to give work to struggling enterprises.

In the process, he said:

Domestic aircraft compete on equal terms with foreign analogues, with world market leaders in many of their characteristics, and by the way, in some [characteristics] — in combat aviation — is considerably superior to them.

Putin’s assessment of Russia’s place as the (or a) leader in military aviation spurred Militaryparitet.com to editorialize. The comments are worth a few moments.

Deputy PM Yuriy Borisov used the occasion, Militaryparitet writes, to ask once again for Putin to erase defense industry’s chronic debts. And nothing in Borisov’s plea smells like the competitiveness Putin claims.

The site continues:

This announcement [about Russia’s lead in military aviation] is highly interesting, but it has been repeated like a mantra for two decades already. So where is Russia outpacing its competitors in combat and military aviation?

First, Russia still hasn’t gotten its fifth-generation fighter, the Su-57, into the force. The U.S. long ago jumped ahead with its F-22 and F-35, and even the Chinese claim they have 40 series-produced J-20 fighters.

Second, Russia’s fourth-generation fighters are laggards. Not a single one has an active phased array radar. This is no longer an innovation for the U.S. The French have it. And China also asserts success in putting it on its fighters.

Third, the Indians are unhappy with Russia’s R-77 air-to-air missiles they purchased. New Delhi says they lack the range and effectiveness of U.S. AIM-120 and European Meteor missiles.

Fourth, with respect to strategic bombers, Russia is renewing production of the existing Tu-160 Blackjack. A new design PAK DA will require “remarkable patience” at a minimum and, with a long-term recession looming, it probably won’t happen at all.

Fifth, Russia hasn’t managed to put an active phased array radar on its AEW aircraft because of its almost total lack of commercial electronics and microelectronics industries.

Sixth, for transports, Russia continues to rely on the Il-76 while the U.S. introduced the C-17 with nearly double the cargo capacity in the 1990s.

Seventh, Russian unmanned aviation is a complete bust. There is the single S-70 Okhotnik, but you couldn’t see a Russian analogue to Global Hawk “even with a telescope.”

Militaryparitet sums up:

So what kind of Russian leadership in combat (military) aviation is Putin talking about every time? Russia has long been on the margins of progress in this sector, and there is no hope to get to the cutting edge “by its own efforts.” We are living in a time when you can’t do anything good without cooperation . . . .

But . . . is there all of a sudden an area where Russia is overtaking the entire world in combat aviation? If there is, speak up, please. We’ll celebrate together.

PAK FA Update

RIA Novosti reports the second T-50 (PAK FA) testbed will begin flight tests before the end of the year, according to Sukhoy chief Mikhail Pogosyan.  He said the first testbed has performed 40 flights.  Sukhoy is satisfied with the course of testing which has gone faster than expected.

Pogosyan added that negotiations with India on its entry into the fifth generation fighter program should be completed this year.  Russia and India will roughly split the development expenses for one- and two-seat versions.  The PAK FA will start to enter the Russian inventory in 2015, and Indian forces around 2020.

5th Generation Engine Delayed?

Work at NPO Saturn

Marker.ru yesterday wrote about NPO Saturn, FGUP Salyut, OAK, ODK, the Defense Ministry, and development of a fifth generation engine for Russia’s fighter aircraft.

Salyut believes it has basically defeated Saturn in the Defense Ministry’s tender to produce a fifth generation engine for the PAK FA, but Salyut fears development will be given instead to the newly created ODK, the United Engine-building Corporation.

Meanwhile, in OAK–the United Aircraft-building Corporation, they think the Defense Ministry may be considering not making a new engine for the first PAK FA model, and instead concentrating engineering resources on development of a 5th generation engine for future modifications of the new fighter. 

Salyut believes it decisively beat Saturn in the tender’s first phase, but the Defense Ministry has not announced the second and conclusive phase possibly because, according to Salyut’s Dmitriy Yeliseyev, the issue of creating the fifth generation engine was automatically decided when Saturn joined ODK.  But Salyut will insist on completing the tender process to decide who will be lead designer for the 5th generation fighter’s engines.

Yeliseyev says:

“We understand that general direction of the work to create an engine for PAK FA will be under ODK, but we also believe the tender is needed to even decide who will develop the gas generator for the future engine, and basically decide who will drive work on the engine for PAK FA.”

Salyut is now focused on modernizing the fourth generation AL-31 engine.  But test models of PAK FA have Saturn’s 117 engine, a modification of the AL-31.

OAK representative Konstantin Lantratov says the fifth generation engine has fundamentally new requirements, particularly in the areas of radar and infrared signature reduction.  OAK believes the Defense Ministry is not announcing the conclusive phase of the tender to build PAK FA’s engines because it’s waiting for the aircraft’s test results with its current engines.

Marker.ru asks is it necessary to make a 5th generation engine right now?  Wouldn’t it be better to concentrate work on producing engines for aircraft that will follow the PAK FA?  If a new engine starts development today, it will be ready in 5-7 years, about the time modernized or other variants of the PAK FA will be appearing [of course, this assumes the original PAK FA is successful and operational pretty quickly].

OAK’s Lantratov seems to think the Defense Ministry should decide now, if it wants to pay for new engines, and is willing to risk paying and not getting the right results.

Marker.ru consults CAST’s Konstantin Makiyenko . . . he thinks the Defense Ministry has no reason to hurry.  ‘Deeply modernized’ fourth generation engines from Saturn and Salyut are meeting VVS and PAK FA requirements, at least during the test phase.

He thinks a real 5th generation engine is 10 years away.  The need for more powerful engines will arise as other variants (2-seat, strike, naval, etc.) of the PAK FA appear.  Over their life cycles, aircraft get heavier and thrust has to keep pace, so more powerful engines would need to appear around 2020 anyway.
