Prospective multi-interceptor.

In the late eighties the Soviet military machine was at its peak.Still, the state allocated money for any projects capable of providing, if not superiority or at least parity with NATO.

In the Mikoyan design bureau were in full swing working on a range of new combat vehicles:

 - Multi-role fighter, the IFIs.

 - Lightweight fighter, PRL.

 - Multi-purpose long-range interceptor, the TIR.

 - Two projects of hypersonic aircraft, 301 and 321.

Sukhoi implement the following projects:

 - Attack ninetieth T-12.

 - Lightweight fighter - single-engined Su-37.

 - A powerful carrier-based fighter P-32.

 - Medium bomber "object 54C."

Despite the "greenhouse conditions" Our aviation industry is likely to be in shock when the U.S. military declassified F - 117 .Fairy tale was real.

What would you do with an almost ready-1.42, in which the construction of "stealth - technology," laid "so far - as".

I do not know.anything, but our designers have managed to justify in the eyes of the military.So much so that even in the mid-nineties, the defense minister, the notorious "Pasha - Mercedes" (Pavel Grachev), called "Stealth" - a myth similar to the SDI!

We must pay tribute, he started the Corps of Engineers urgently rectify the situation.Already in the late eighties in the aviation Chipboard - literature began to appear serious analytical articles on the reduction of ESR (effective area of ​​dissipation).

It is possible that even then began to think of deep modernization of the IFIs.If the Soviet Union did not "kiss off" in 1995 under the symbol 1.42 MiG-35 would be referred to the series, and a new multi-purpose machine is fully compliant with the fifth generation could appear as early as 2005.

Current PAK FA despite the fact that is the biggest fighter in the world (according to Indian press its gross weight exceeds 35 tons) is still a line of domestic "fighter - bombers" previously provided MiG-29 (maximum weight - 18 840 kg) and MiG-21 (9400 kg).It is significant that leap across the generation doubles the maximum takeoff weight.

It is understood that work on the line "fighter - interceptor" just being.Outpost in the case, after the disappearance of the race OKB "MiG" with its 1.42, a bureau, "Dry."Forward-looking machine that could replace the MiG-31 for funding can be considered a response to American "regional bomber".

Multifunction MFP Interceptor (call it so, so as not to be confused with the MFI of the nineties), in terms of revenues for service should be referred to the sixth generation of fighters.Although the requirements for the "Generation - Six" has not yet developed, it is obvious that constitute the backbone of his drones.Therefore, prospective car would have all the necessary qualities, such as: takeoff and landing, air intercept and attack ground targets in fully automatic mode.The main purpose of the same MFP - " armed airborne command post. "

According to statistics, maximum takeoff weight of the new interceptor will be comparable to the MiG-31M and will be 50 - 55 tons.This scale will be placed in the compartment is not only a weapon of class "air - air", but rockets "air - ground".Range of machines will allow without refueling accompany long-range bombers and bring her into the category of "strategic systems."

In order to ensure flight at low altitude and short takeoff - landing MFP can be equipped with a variable sweep wing.

Record take-off weight interceptor will also require heavy-duty engines.

In the article "The long-term aviation complex tactical aviation in Russia"  project is referred to the new aircraft engine which creates "Design Bureau of emerging technologies" (KBPR) included with the company "Salute" and SUE "Zavod im. Klimov."

Thrust it is reported to be 25 000 kg.It is also possible that the engine will have the opportunity to change the degree dvuhkontrunosti, although it does lead to a complication of construction, but will get the best fuel consumption for both subsonic and supersonic flight regimes.

Despite such attractive prospects a chance to build such a large machine is virtually zero, even a piece of equipment was created as part of the T-50 Sukhoi which can be applied to the MFP does not allow to reduce the enormous (in the Russian budget) expenditures that pertain to its creation.R & D costs could reach 7.5 - 10 billion mantas.dollars.

Presented with a wing-type arrangement "scissors" has been studied at the junction of the eighties and nineties when the illusion of the benefits the reverse sweep has not yet been broken on the rocks of practice.The highlight of this option is one that is common to both wings of the axis of rotation, although it is not clear how this can be done in a fairly wide center section.Another option is less exotic, and therefore closer to reality - the usual trapezoidal wing with a fully adaptive front and rear edges.

The network has a promising movie with a Russian plane: Video

Analysis of the model presented in the video, suggesting the authorship of the Sukhoi Design Bureau.Take-off weight of this machine should be attributed to the multifunction interceptor.

Area:

Wing 75 sq. m
40.75 sq.m side view
Front View of 14.34 sq.m
view from above 137.72 m

The volume of 43.17 cubic meters

That is, maximum takeoff weight of the machine is in an area 39 - 43 tons.Dimensions 5.7 x main compartment 2.6 x 0.82 meters, which allows you to easily place it in four missiles ultra distance.Two side compartments - 2 short-range missiles.Two engines with afterburning thrust of 16,000 kg at least, in size suitable perspective from motor PAKFA .

In his book "The problems of promising aerospace engineering," a collection of articles researchers TsAGI.Among the different enough interesting material published an article "On the issue of improving the aerodynamic efficiency of supersonic aircraft at subsonic speeds," the authors of VG Kazhan and AP Dyachevsky.The essence is as follows:

"... The most important task of aircraft aerodynamic design of multi-mode is the determination of optimal aerodynamic contours, providing an increase in aerodynamic efficiency at supersonic as well as at subsonic speeds.

Implementation of a supersonic cruise flight requires a thin swept wing leading edge with optimum deformation of the middle surface of the aircraft, providing self-balancing on a given flight mode and a set of longitudinal static stability margin.

At the same time at subsonic flight speeds of the main effect to reduce induced drag of a thin wing is achieved through the implementation of suction force on the wing leading edge, which reduces the coefficient of induced drag by more than 2 times.Note that the effect of optimizing the distribution of circulation along the span of only a few percent.

As a result, multi-mode aircraft the most efficient way to increase aerodynamic efficiency at subsonic flight speeds is the use of adaptive mechanization (or wing profile with a variable curvature).The high level of aerodynamic performance is achieved by restoring the suction forces at the leading edge of a thin curved wings at subsonic speeds and low impedance of a flat or optimal for supersonic cruise deformities of the middle surface. "

In addition to charts and formulas and present a simplified model of the purge, the processing which has led to the pictures "FIP - TsAGI."

This is a great fighter with advanced PGO and obviously not referring to the super-maneuverable aircraft, which however is difficult to implement at take-off weight of 50 - 60 tons.The wing area of ​​113 square meters with an adaptive multi-mode slats gives the car without the use of variable sweep.Quite roomy payload bay with 7-m and a width of 2.6 m. The location of air intakes motors not shown, presumably on the top, sides of the fuselage.The bow of the Su-33KUB.

To date, this is the first mention in the official press about the project.
