Yes, there were. I hope MiG could use its MiG-1-44 concept to develop it.

At that point, why not just take back the design for the J-20 from China and make some improvements from there?medo wrote:Ivan the Colorado wrote:Wasn't there talk about a long range, high speed interceptor to replace the MiG-31 in the long run Berkut?

MOSCOW, Aug 12 — RIA Novosti, Yekaterina Spirovska, Alexander Nevar. Work on defining the shape of the radio-electronic complex of a promising aviation complex distant intercept (PAK DP), which will replace the MiG-31 began in "NIIP Tikhomirov", reported to journalists the General Director of the enterprise Yury Belyi.
Last year the Russian air force commander Colonel-General Viktor Bondarev said that Russia in 2017 will begin research work on the development of PAK DP. Readiness to participate in the development of the aircraft in February this year, said the RAC "MiG".
"Development system "Zaslon" of the fighter-interceptor MiG-31 has been a milestone for our Institute and became his "calling card". So, of course, we couldn't stay out of participation in the creation of new radio-electronic complex for PAK DP. Started research work on determination of appearance-based systems not only modernized "Zaslon", but for all of the latest developments, including "bars", "IRBIS", radio-electronic system for the PAK FA and others," said Belyi.
He noted that for the new interceptor should be developed on a modern basis and all other systems.
"If NIIP will be chosen by the developer of electronic industry, we will need to ensure communication with all onboard systems. We are also ready, have the necessary experience," added the CEO of the developer.
NIIP is a developer of systems management service (OMS) fighter aircraft, as well as the developer of anti-aircraft missile systems of medium-range air defense Ground forces, whose task is to protect against air attack. Currently the shareholders of "NIIP Tikhomirov" are "Concern PVO "Almaz-Antey" (56%) and "Concern radio-Electronic Technology" (44%), part of state Corporation Rostech.
MOSCOW, August 12 - RIA Novosti. Development work on the development of perspective aviation complex long-range interception (PAK DP), which in the future will replace the MiG-31, will begin no earlier than 2019, told journalists on Wednesday VKS Commander Colonel-General Viktor Bondarev.
"Start of development work on the creation PAK DP planned no earlier than 2019. At the moment, the Russian Defense Ministry has successfully carried out the modernization of existing facilities interception - the MiG-31," - said Bondarev.
He noted that the timing of the ROC to build PAK DP does not affect the status of the park interceptors videoconferencing.
Last year, Bondarev reported that Russia in 2017 will begin research work on PAK DP. And earlier on Wednesday CEO NIIP VV Tikhomirov Yury White announced that the company has already begun work on the definition of the complex shape of electronic interceptor future.

MOSCOW, August 12. /TASS/. Research and development for the creation of a new generation long-range interceptor-fighter to replace Russia's MiG-31 will begin no earlier than 2019, the commander in chief of Russia’s Air and Space Forces, Colonel-General Viktor Bondarev said.
According to earlier reports, the MiG-31 upgrade program will provide the Russian armed forces more than 130 MiG-31BM fighter planes.
a triangle like wing would help?GarryB wrote:As far as I know the forward swept wing is ideal for subsonic aircraft but in theory it should also be rather more efficient for high speed flight too.
For those not familiar a very simple explaination is that a straight wing generates more life but also generates more drag. The faster you fly the more drag is created so as you get faster a sweep back of the wing can reduce drag while still generating lift.
the main problem is that sometimes the air does not just flow straight over the wing and with very sharply swept wings the air can flow down the sweep. When it gets to the end of the wing the high pressure air and the low pressure air mix and form a huge vortex that generates parasitic drag.
One solution is the wing in ground effect where short broad wings are used on aircraft that fly very close to the ground so the vortex does not form properly and drag is greatly reduced.
another solution is winglets which reduces but does not eliminate the vortex.
Another solution is wing fences but again these do not eliminate the vortex.
the forward swept wing results in the span wise flow heading towards the wing root instead of the wing tip so the wing tip vortex is practically eliminated as a significant force on the aircraft.
careful design allows the spanwise flow to add to lift by flowing over the lifting body fuselage instead of creating a vortex at the wingtip.
The direct result is an enormous reduction in drag, which means the wing can be made smaller and lighter... which further reduces drag etc etc.
The main problem is that in a turn the forces on the wing tend to make it bend upwards which increases the lift and drag and would increase the turn rate which rapidly turns a slow turn into a broken wing.
Modern laminates that are rigid in one direction and relatively flexible in the other promised a forward swept wing strong enough not to break in a turn but flexible enough to promise an active reshapable wing so you can have it flat and low drag for high speed flight and curved and high lift for takeoff and landing. A really active wing could mean no leading edge slats and flaps which would greatly reduce RCS as well.
Personally I would think if they can solve the problems of high speed a forward swept wing offers lower drag and higher lift.

That means the vertical stabs won't be blocked by wing and hull at high AoA.
Сегодня становится очевидным, что через какое-то время изменится характер угроз, исходящих от средств воздушного и воздушно-космического нападения. Произойдет их частичная интеграция, что потребует создания новых средств защиты. Руководство государства это понимает. Подтверждением служит создание нового вида Вооруженных сил - Воздушно-космических сил России
It was about time they start to think of that....jhelb wrote:PAK-DP will feature aerospace defense capability

Keep in mind this is an interceptor... so long range, high flight speed, ability to fly very high or very low if needed are all useful features along with very big radar/sensors, and significant payload of air to air weapons...
High manouver capability, along with stealth are secondary and would actually likely reduce performance in more important areas.
Twin fins is good for stability, but two fins is twice as heavy and increases drag compared to one.

High-altitude fighter-interceptor MiG-31, which according to experts still do not have analogues in the world, can become the basis for the creation of modern high-altitude combat aircraft MiG-41, said, "Interfax-AVN" on Wednesday, a member of the Duma Committee on Defense Alexander Tarnaev.
"This view is not only deputies, but also the development and production of this unique aircraft, which they expressed in the visiting session of our committee in Lukhovitsy near Moscow (branch corporations" MIG "-" Interfax-AVN ") and Nizhny Novgorod plant" Sokol "where serially produced MiG-31, and is now undergoing modernization, "- said A.Tarnaev.
He said that in response to the appeal of the State Duma deputies to the country's leadership, decided to include the project of creating long-term high-altitude interceptor, the new armament program with the terms of the realization in 2020. "This car will be the further development of the fighter-interceptor MiG-31, which is a decade ahead of its time. We do not exclude that its development can begin before 2020, since such a plane is very necessary to our armed forces," - said A.Tarnaev.
According to him, some time ago there was a special meeting of the Defense Committee of the MiG-31 interceptor. The participating experts noted the unique characteristics of the aircraft. Managing Director - General Designer of "" OAO Alexander Inozemtsev, for example, said that the design features of the fuselage such that when you install new engines on a plane, he might even go hypersound.
"As far as I know, all were built more than 500 high-altitude interceptor MiG-31. In the ranks is currently in the order of 100 machines. Until such time as the MiG-41 begins to enter the army, the last modernization of high-altitude interceptors will remain in the Air- Russian Space Forces, "- said A.Tarnaev.
He said that thanks largely to the support of the State Duma deputies managed to preserve this unique aircraft in service and start its modernization. Today the modernized MiG-31BM has come into force. "Last September, during a working visit of members of the Duma Defense Committee in the Nizhny Novgorod region and visiting the plant" Sokol "we had the opportunity to personally make sure that there is a large-scale modernization of the MiG-31. The plant successfully fulfilling the state defense order for the modernization of MiG-31. It is pleased that the legendary plane again, "stands on the wing," - said A.Tarnaev.
The supersonic fighter-interceptor MiG-31, developed by the Russian Aircraft Corporation "MiG". It is designed for long patrols and combat high-altitude reconnaissance aircraft, strategic bombers and low-flying targets. Aircraft was produced at the Nizhny Novgorod aircraft building plant "Sokol" In total, between 1976 and 1994 were issued 533 aircraft of various modifications.
Earlier, Deputy Assistant Director General of RAC "MiG" Mikoyan Hovhannes (son Artem Mikoyan aircraft designer) told reporters that the fighter-interceptor MiG-31 has a high potential, he will be able to successfully operate a century.
"This - is my favorite airplane. Even a hundred years, he can defend our sky, because it is - a unique machine that has no direct analogues abroad. It is made of steel and titanium, has a maximum speed of 3 thousand kilometers per hour. Four fighter-interceptor MiG-31, operating in a single information field, may block the front of 900 km, tracking and destroying dozens of foreign cars. " - O.Mikoyan said.
The contract for the modernization of the 2019 order of 60 MiG-31 was concluded with the Ministry of Defense of the Russian Federation in 2011.
The upgraded MiG-31BM has a modern management system, target detection range up to 320 km, the defeat - 280 km. The aircraft is capable of simultaneously hitting 6 and track up to 10 air targets. Due to the avionics and weapons of the new generation of the effectiveness of the MiG-31BM compared with the MiG-31 has increased by 2.6 times
