New plane, in most sources simply called FIP ("Multi-interceptor"), first XXI century should had come to replace the MiG-31. He had to have a number of advantages over its predecessor, as crews and technical and military character. It was assumed that the MFP will not just be an interceptor, but armed with air-command pt. This means that a set of avionics new interceptor had to continue the ideology inherent in the MiG-31. In the benchmark MFP planned able to quickly come to the area to intercept, detect targets at bolshennom delete and create their attack, preventing the convergence of the distance of a retaliatory launch. In addition, the aircraft could get another puzzle, in part similar to the goal of distant aircraft radar detection. MFP could transmit information about the found for the land and the other planes also participate in the attack, highlighting its own radar emission targets.
Unfortunately, due to comparable nedavneshnih works, and their status on the draft MFP understood not so much. In this case, the available information on its technical properties of virtually represents estimates based on different information from different sources and analysis capabilities. More possible subsequent appearance looks promising interceptor. Plane length of about 24 meters and a wingspan of about 19-minute. The highest takeoff weight of the aircraft is estimated at 50-55 tons in dry weight interceptor 25-27 tons. Under certain circumstances, the required load IPP could exceed 10 tons. To achieve the applicable aircraft flight characteristics needed to be equipped with 2 turbojet engines with afterburning thrust of 25,000 kg. With such power plant IPP could accelerate to 2,500 miles per hour and to take long flights with little lowest speed, about 2200-2250 km / h When the supplies of fuel to 16-16,5 tons plane could fly at a distance of up to 9-10 thousand kilometers. At the same time, the features of the interceptor would reduce the radius of the act to 2-4 thousand kilometers.
As you know, at the end of the 80 considered several options for the design of a promising build interceptor. From their special attention is made in accordance with the concept, which received the title of "scissors". This concept involves the simultaneous use of 2-descent noticeable technologies: a variable sweep wing and the back of the wing sweep. During the study itself latest version of the MFP does not seem something of a purely experimental, and the designers had hoped to receive from the reverse sweep a real benefit. During takeoff and landing aircraft wing MPA had to be trapezoidal in plan. After reaching cruising regime aircraft mechanics set in motion the console, then the plane were divided by strips perpendicular to the longitudinal axis of the interceptor and sprawling forward and backward. In the end, such "transformation" airplane plane had to be an X-shaped structure. It is interesting that the two halves of each arm was planned to strengthen a common axis. A similar system would be very difficult from a technical point of view, but had certain advantages over fixed wing, similar to its take-off configuration.
Apparently, the system of "scissors" was very difficult for the likely implementation in practice. Because in the next it was abandoned and returned to more conventional options. There is information on the development of a trapezoidal wing in several versions. With all of this like it was planned to make the bearing surfaces is quite adaptive. Due to the constant configuration of the wing profile was supposed to make up the loss in flight characteristics, caused by failure of the back-swept wing. As for ease of manufacturing and durability, the trapezoidal wing was even easier and more convenient "scissors." After all, at some images of the alleged airplane MFP There is a positive variable sweep wing. Noteworthy that with all the variations of the wing promising Interceptor had about a similar aero assembly. He was an integral longitudinal triplane with front and tail horizontal tail, vaguely reminiscent of piloting Sou-47.
The fuselage of the integrated interceptor assembly in its contour of probably had to recall the respective unit of the Su-27. Double cabin aircraft could be similar to the cockpit combat training Su-27KUB frontline fighter or bomber Su-34. Given the anticipated time of the adoption of the IPP can be adopted to make the approximate conclusions about the composition of avionics. Most likely, the interceptor equipped with a radar with an active phased array antenna suitable massive computing system monitors and functional cabin.
Regarding the arms of a promising functional interceptor information is available. Perhaps it could be equipped with an automatic gun, 23 or 30 mm, as a kind of supports for the suspension of missiles "air-to-air." In some sources indicate 20 holders, but the size of the aircraft they say directly about the impossibility of placing such attachments. More possible setting looks less than 10-12 pylons and supports. On their plane could carry large missiles and very long distances, such as R-33 or R-37. It is easy to imagine the efficiency of the level of MFP 4 aircraft carrying at least 10 missiles R-33 with the largest range of about 150-160 km.
As we see, the draft MFP promised huge tactical advantages over enemy aircraft. According to its features of one aircraft FIP would be equal to two or three MiG-31, which would strengthen the protection of the air borders of the country. But the air force of in the end and have not received a new aircraftInterceptor. The fact is that the most critical stages of project development — end design, build and test the most experienced standard — because of the collapse of the Union of Russian would come to far not the best of times. In connection with this, apparently, project MFP has been frozen or even closed. When prices applets more than 5-7 billion U.S. dollars, our country simply does not have pulled the
end of work and the start of production of a promising interceptor.
Despite the prepyadstviya project MFP, from time to time are references to a hidden design, created at the moment in the company "Sukhoi". Maybe the financial situation with the passage of time is allowed to return to the undeservedly forgotten by the IPP project or develop on it were used in the development of new aircraft. Either way, now there is no official data on the fate of the upcoming and future functional interceptor. If the project really was forgotten and not continued, in subsequent years, mostly languid interceptor Russian Air Force MiG-31 is the later modifications, which has no successor.
