Giới thiệu về Su-27SKM và Su-30MK2

Các bạn nói về ra đa của F-22 là từ đây
With the APG-77, the F-22 will be able to detect an enemy aircraft''s radar from distances of up to 460 kilometers (250 nautical miles). It will be able to acquire an enemy aircraft with radar at distances of up to 220 kilometers (125 nautical miles), while its ""low probability of intercept"" radar signal will be very difficult to detect and the ""stealthy"" F-22 will remain invisible to the enemy''s radar.
vậy 460 km là phát hiện ra tín hiệu ra đa còn phát hiên ra máy bay phát ra đa là 220 km. bây giờ các loại máy bay mới của Nga nhất là Su-27/30 đều có chế độ bay yên lặng tới mục tiêu ( radio silent ) còn Mi-31 có chế độ datalink nên một máy bay này có thể bắn tên lửa đến mục tiêu do máy bay khác phát hiện
Although the MiG-31 is capable of autonomous operation, the Soviets did not abandon their ground-control network by any means, and the Foxhound can be directed semi-automatically by the AK-RLDN ground-based automatic guidance network using the aircraft''s APD-518 digital datalink and BAN-75 command link. The datalink can also be used to hook up the fighter to an Antonov An-50 ""Mainstay"" airborne warning and control system (AWACS) aircraft, as well as allow ""wolfpacks"" of four MiG-31s to cooperate under the control of a flight leader, covering a swathe of airspace 900 kilometers (560 kilometers) wide. The flight leader can direct his three wingmates to specific targets.
The MiG-31 features other improved avionics, including updated radios; IFF; RHAWS; and particularly an NK-25 navigation system, featuring receivers for the Tropik medium-range radio navigation system, similar to the US LORAN, and the Marshrut long-range radio navigation system, similar to the US Omega. One of the motivations for such extensive navigation gear was to allow the Foxhound to patrol deep into Arctic airspace in search of Western cruise-missile carrier aircraft. Trial flights included such deep-arctic sorties, including one that overflew the North Pole.

He he, mấy bác pro-US úp sọt HuyPhuc rữ quá. Có một điểm lý thú đó là dù radar của F/A 22 được quảng cáo như vậy nhưng AIM-120 AMRAAM lại có tầm thua kém R-33 và R-37 rất rất nhiều. Thực tế là radar của MiG-31 có khả năng phát hiện từ 400 km và R-37 dư sức để tiêu diệt mục tiêu từ khoảng cách này. Vậy nên chưa biết F/A-22 sẽ sử dụng ưu thế radar như thế nào đây? Để quan sát máy bay mình bị tên lửa đối phương bắn tan xác thế nào chăng?

Hoan hô gulfoil, vote phát nào.

It is claimed that an unit of MiG-31 can link their radars together, to establish a search pattern - covering a width of 800-900km with four aircraft, spaced at 200km. APD-518 radar system for "silent" attacks
--------------------------------------------------------------------
Lâu lắm tôi mới có dịp quay lai box KTQS, tiếc là cái thời thành viên trong box người ta chú trọng vào việc tìm hiểu khía cạnh kỹ thuật và chia sẻ hiểu biết với nhau đã xa rồi thì phải.....
Các bạn này, thực ra thông tin chúng ta có qua internet độ tin cậy lắm lúc vui như truyện cười.Dẫn chứng hén:
Theo link của Nga : http://www.aviation.ru/MiG/index.php Thì APD-518 là radar system for "silent" attacks
Một cái link của Nga khác : http://warfare.ru/?linkid=1601&catid=255
Thì APD-518 là digital air-to-air data link
Theo một cái link khác : http://www.defencetalk.com/air_systems/fighters/mig-31_foxhound_3.html
Người ta nói rất rõ ràng radar của Mig-31 là loại zaslon, version RP31-zaslon radar. Còn APD-518 dịnh nghĩa như sau:
Other three MiG-31s have APD-518 digital data link to lead aircraft, permitting line-abreast radar sweep of zone 430 to 485 n miles (800 to 900 km; 495 to 560 miles) wide by 140º sector scanning angles
Các bạn vào các link đó , dùng Ctrl + F và các key word để tìm cho nhanh. Chúc mọi ngưòi vui vẻ

Hình như mấy cái này được bàn từ khá lâu rồi thì phải.
F22 có tầm detect lớn,nhưng MiG lại có tầm track và control lớn hơn nhiều.
Dù vậy so gì thì so chứ 2 thằng này sinh ra không phải để đánh nhau.Tình huống Su 27 đánh F22 có lẽ thực tế hơn.
Em thì cho rằng R33 và R37 không diệt F22 được dù tầm xa mấy,tất nhiên trừ phi F22 đeo JDAM bay ì ạch mà lại trớ trêu bị phát hiện .Nếu R77 thì là chuyện khác,nhưng chưa thấy nói đến Mig31 chơi đồ này (chắc đồ xuất khẩu sẽ có chăng ?)
Mà dù Mig31 có xịn mấy chăng nữa nhà ta cũng chả rờ đến nó đâu mà ham
Chúc các bác cãi nhau zui zẻ.

Đây còn 9 cái nữa cho vừa một chục . Radar nó là như thế ạ .

Avionics were significantly improved. The main sensor is the SBI-16 (S-800) ""Zaslon"" (""Shield"" / NATO ""Flash Dance"") phased-array / electronically steered radar, the first such type of system to reach first-line service in a Soviet fighter, with 120 degrees coverage; excellent look-down / shoot-down capabilities; maximum detection range of 200 kilometers (125 miles); and maximum tracking range of 120 kilometers (75 miles). The radar can track ten targets and engage four of them at one time, with the targets prioritized by the interceptor''s mission computer. A semi-retractable TP-8 IRST is also fitted as a passive sensor. Both are linked into an Argon-15 digital fire-control computer.
Although the MiG-31 is capable of autonomous operation, the Soviets did not abandon their ground-control network by any means, and the Foxhound can be directed semi-automatically by the AK-RLDN ground-based automatic guidance network using the aircraft''s APD-518 digital datalink and BAN-75 command link.

AVIONICS:
Zaslon electronically scanned phased-array fire control radar (NATO ''Flash Dance'') in nose, with search range of 108 nm (200 km; 124 miles) and tracking range of 65 nm (120 km; 75 miles); capable of tracking 10 targets and attacking four simultaneously; retractable infrared search/track sensor under ****pit; radar warning receivers.
3 - http://en.wikipedia.org/wiki/Mikoyan_MiG-31
The MiG-31 was the world''s first operational fighter with a phased array radar, the extremely powerful Zaslon S-800. Its maximum range against fighter-sized targets is approximately 200 km (125 mi), and it can track up to 10 targets and simultaneously attack four of them with its R-33 (AA-9 ''Amos'') missiles. It is claimed to have a limited astern coverage (perhaps the reason for the radome-like protuberance above and between the engines) The radar is matched with an infrared search and tracking system (IRST) in a retractable undernose fairing. Up to four MiG-31s can coordinate via datalink, spaced up to 200 km (125 mi) apart to cover a wide swath of territory. The radar is controlled by the backseater, whose ****pit has only two small vision ports in the sides of the canopy, limiting visibility.
4 - http://www.aeroflight.co.uk/types/russia/mig/mig-31/mig-31.htm
MiG-31 was the world''s first operational aircraft to use a Phased Array radar - i.e. it scans electronically rather than by moving the radar antennae physically. The Zaslon S-800 radar can track fighter-sized aircraft from 125 miles away and bigger aircraft from 250 miles away. It is claimed that several Foxhounds can link their radars and thereby simultaneously scan a much larger amount of airspace.
However, it was also planned that the MiG-31 could operate semi-automatically, being directed towards a target by the AK-RLDN ground-based automatic guidance network, using the aircraft''s APD-518 digital datalink and BAN-75 command link.
5 - http://www.aeronautics.ru/archive/vvs/mig31-01.htm
Radar: NIIP N007 S-800 SBI-16 (RP-31) Zaslon or Zaslon-A electronically scanned phased-array fire-control radar (NATO `Flash Dance'') in nose; search range of 108 n miles (200 km; 124 miles) in clutter-free forward sector; range in rear sector 48 n miles (90 km; 56 miles); capable of tracking 10 targets and attacking four simultaneously.
MiG-31s have APD-518 digital datalink to lead aircraft, permitting line-abreast radar sweep of zone 430 to 485 n miles (800 to 900 km; 495 to 560 miles) wide by 140" sector scanning angles. Semi-retractable Type 8TP IR search/track sensor under ****pit; tactical situation display. BAN-75 command link; APD-518 digital air-to-air datalink; Raduga-Bort-MB5U15K air-to-ground tactical datalink; SPO-155L RHAWS; Argon-15 digital computer.

In four-aircraft group interception mission, only lead MiG-31 is linked to AK-RLDN automatic guidance network on ground; other three MiG-31s have APD-518 digital datalink to lead aircraft, permitting line-abreast radar sweep of zone 430 to 485 n miles (800 to 900 km; 495 to 560 miles) wide by 140? sector scanning angles
7 - http://www.globalsecurity.org/military/world/russia/mig-31.htm
The most capable Russian air defense interceptor aircraft, the FOXHOUND has a multiple-target engagement capability and was the first Soviet fighter to have a true look-down, shoot-down capability. The N007 Zaslon radar was the first electronically scanned phased array radar to enter service in the world. It could scan 200 km forward and track 10 targets simultanieously.

although Yuri Guskov, chief designer at Phazatron, has stated that the radar operates at "slightly lower than S- band" which corresponds to NATO''s D-band. This raises more questions than it answers, since some Western analysts suggest that such a waveband would give a wide beam and inadequate resolution at long range. I- or G-bands are felt by some to be more likely, and Aviation Week stated that the radar operated in the mid l-band (9-9.5 GHz). All signal processing is digital.
Radar performance IS Impressive, with a detection range (for a target with 16 m2 (172 sq ft) cross-section) of 200 km (124 miles) and a tracking range of 120km (74 miles). The phased array antenna allows the beam to sweep through 120 degrees in azimuth and from 70 degrees above the nose to 60 degrees below.
MiG-31s are most often used in group of four (or even eight), linked together by datalink. Operating together, four MiG-31s can cover a strip of territory 900 km (560 miles) across,
....................................................................................................
However, this factor that gave Russia an advantage ten years ago is losing its significance as technological equipment is aging, the headway made in science and technology in the Soviet times is fading and the average age of the personnel at design bureaus and industrial facilities is growing.

các bạn ơi-không ai sai cả đâu vì các mạng lấy số liệu cũ và mới.Nếu mig-31 có từ năm 1977 thì đến 1984 mới bắt đầu cải tiến về ra đa , động cơ , và vũ khí và gọi là Mig-31M ( modernized )và ra đa là Zaslon-M có tầm xa phát hiện mục tiêu gần gấp đôi so với ra đa cũ (320 km )
MiG-31M (product 05)
Improved FoxHound
long-range interceptor
A two-seat supersonic fighter-interceptor, further development of the MiG-31 with a new weapons control system designated Zaslon-M ( 320Km). The aircraft is equipped with a radar featuring a doubled effective range, which is capable of simultaneously tracking and engage more targets. The MiG-31M main armament is six long-range missiles under the fuselage in tandem, three abreast and four RVV-AE medium-range missiles under the wings, the cannon is dismantled. The aircraft design is somewhat updated - the middle fuselage fairing cross-section is larger, the ****pit canopy features a caseless windshield and smaller area of the operator''''s transparency, the wing is equipped with large leading-edge extensions, the infrared direction finder under the forward fuselage is non-retractable. It is powered by enhanced D-30F-6M engines. The internal fuel tank capacity was increased. The aircraft has an in-flight refuelling capability. The ECM and individual defence systems are united into the integral defence system.
The operator''''s ****pit control board equipment was changed.
Test-pilot Boris Orlov and test-navigator Leonid Popov flew out the prototype (registration number 051) on 21 December, 1985. In the late eighties, the Sokol aircraft plant (NGAZ) built the development batch of the MiG-31Ms, which underwent the official testing successfully.

MiG-31B/BS
(product 01B, product 12, product 01BS)
FoxHound interceptor
A two-seat supersonic interceptor, the MiG-31 derivative with an improved Zaslon-A weapons control system, superior long-range missiles (R-33S), ad***ional missile (the R-40TD medium-range missiles and R-60 short-range missiles), modernised navigation computer and new data exchange modes. MiG-31B was equipped with in-flight refuelling system from airplanes - tankers of Il-78 or Su-24T. Time in flight with drop tanks - 3,6 h, with refuelling - 6-7 hours. and in-flight refuelling system.
July, 30, 1987 test-pilot Roman Taskaev and test-navigation officer Leonid Popov for the first time in world practice have flown by on a fighter - interceptor above North Pole on a route Monchegorsk - Polus - Anadyr (Chukotka). It has been mass-produced at NGAZ Sokol since 1990.
MiG-31BS - that designation was given to the MiG-31s updated at Sokol plant to the MiG-31B aircraft capabilities, but not equiped with in-flight refuelling system.
In the beginning of 90th years because of shortage of means at Russia Ministry of Defence of purchase of fighters the MiG-31 were stopped. It is constructed more than 500 interceptors, more than 350 from which now are on arms of air force of Russia. Some tens MiG-31 are present also in air force of Kazakhstan.
