PAK FA engine postponed
Around the engine for the PAK FA project unfolds scandalous story. The right to create such an engine is challenged in the past year at the preliminary tender Defense Rybinsk Saturn and metropolitan Federal State Unitary Enterprise "Salut". Representatives of the "Salute" claim that their project is then scored a convincing victory, and believe that Defense should undertake a second, final stage of the tender. But the Defense Ministry with pulls. The guide Salyut fear that after the establishment of JDC military department can automatically give the order for engines for the PAK FA to the company. In the KLA also admit that the reason for delays in the other: the Ministry of Defense is now being discussed the option does not make the engine of the fifth-generation PAK FA existing samples, and to focus engineering resources on creating an engine of the fifth generation has the following modifications of the fighter.
"Salute" declares victory
On the first phase of the tender "cookie" is told in the Air Force and the "Salute." "We participated and" Saturn ", - says Director of Information Technology" Salute "Dmitry Eliseev. - Pre-tender consisted of two phases. Salyut performed work on both. In the summer of last year received the Commission's opinion, which says that we have fulfilled requirements of both phases of the contest without reproach. "Saturn" the first stage carried out with serious criticism, and the second stage did not comply.
The second stage of the tender Defense has not yet been announced. "Maybe someone at the top think that after the" Saturn "became part of the JDC, the question of the creator of the engine for the PAK FA decided to automatically" - complains Representative "Salute". The company believes this approach is wrong and going to continue to insist on holding the contest to determine who will act as the lead developer engine for fifth-generation fighter.
"We understand that the general management of the development work on the engine for the PAK FA will be for the JDC, but we also believe that the tender is required to even determine who will build a gas generator for the future of the engine, and on this basis to decide who will be the ideology of work over the engine for the PAK FA "- contains the position of his company Dmitry Eliseev.
In the KLA believe that the solution must take the Defense Ministry
Today's development of "Salute" - it is in any case, upgrading the engine of the fourth generation of the AL-31, reminiscent of the KLA. The prototype of the PAK FA aircraft experienced now fitted with an engine 117, which also represents a modification of the AL-31, performed Saturn. "The engines of the fifth generation are presented fundamentally different requirements, in particular in terms of radiozametnosti and visibility in the infrared range," - says Director of Corporate Communications KLA Konstantin Lantratov.
In the KLA admit that the Defense Ministry did not announce the final stage of the tender for the right to create an engine for the PAK FA is awaiting test results from the current aircraft engine. Representatives of the Ministry is something to think about. Do I need to do fifth-generation engine for the PAK FA right now? Is not it better to concentrate on production of engines for aircraft, which will monitor the PAK FA? If you start to drive today, for its production will require 5-7 years, it is in these terms is expected emergence modernizirovannnoy versions of the PAK FA.
"Decide to be the Defense Ministry - says Lantratov. - There will be whether they have money now to pay for the development of a new engine? Also need to assess possible risks: Is there a belief that the customer gets exactly the result which counts, it is in those terms? "
Experts say no hurry
"Defense is really nowhere to hurry - said deputy director of the Center for Analysis of Strategies and Technologies, Konstantin Makiyenko. - Those deeply modernized engines fourth generation, which is a" Saturn "and" Salute ", now meet the needs of the Air Force, including providing the needs of the PAK FA, on At least on the test stage. "
The need for this engine is the fifth generation - by weight, dimensions, specific, technical characteristics - will be really about 10 years, experts say. In this sense, while at the Ministry of Defense is, because the need for a capacity of traction and other characteristics of the engine will arise when there are heavier versions of the aircraft - two-seater that is optimized under the shock problem, perhaps by basing on aircraft carriers. And also a version for India, optimized for high-altitude and high temperature conditions.
"In general - continues to Makienko - there is such a pattern: aviation complex in the process of life - he lived from 30 to 50 years - on average heavier by 1% per year. That is, through its life cycle traction necessary to increase by 30-50% . Therefore, increasing the energy capacity of the engine will be relevant not before 2020, when they start to appear heavy-weight version of the aircraft.
