Giới thiệu về Su-27SKM và Su-30MK2 (PART-2)

Cái bản vẽ con T10 - 12 có từ tháng 11 - 1974 rồi cơ à ? Thế thì chẳng biết ai copy ai nhỉ ?

Phiên bản AIM-120C-5 tầm bắn là 65 miles ~ 105 km, phiên bản kế tiếp AIM-120D tầm bắn được nâng lên 50% ~ 112 miles ~ 180km, lô hàng đầu tiên dự kiến giao là vào tháng 12/2007.

Mình nói vậy là so sánh F-22 và PAK FA vì ở F-22 thì khoang vũ khí chính ở bụng máy bay mang được 6 tên lửa AIM-120C là loại chế tạo riêng và kích thước có làm gọn lại và cánh gập để rành riêng cho F-22 đặt vào khoang vũ khí trong thân máy bay vì kích thước của khoang hẹp.Còn hai bên thì có 1 tên lưỉa AIM-54.Bây giờ đã có AIM-120C-7 nhưng lại dài hơn đâu 15,2 cm nên chưa có thông tin gì cho F-22 ? Vậy tầm bắn của F-22 là bao nhiêu ?
AIM 120C
Located in the ventral bays, the F-22 is armed with six AIM-120C Advanced Medium-Range Air-to-Air Missiles (AMRAAM). Weapons armament on the F-22 turned out to be a controversial issue in the past. In preferred con***ions, a fighter such as the F-22 with internal weapons bays should have a compact missile with folding fins. This con***ion would mean the F-22 could not carry standard missiles. An anticipated problem of internal missiles with folding fins is they may not be capable of withstanding stresses when carried externally on current fighters. The latter is not acceptable in this modern age in military hardware. This is because of the ability for almost all Air Force weapons to be used on its current fleet of fighter aircraft. The ability for Air to Air and Air to ground weapons to be carried on multiple aircraft cuts down on costs and maintenance support
The Aim 120C is a compromise. Reason being, the tails and wings of the missile have been reduced in size with the intent for the missile to fit better into internal bays. Best of all, there are no performance compromises with the reduction. In ad***ion, the USAF has announced the AIM-120C will become the standard version for all of its fighters. The Aim-120C''''''''''''''''s will be propelled off of the missile rack inside of the weapons bays by pneumatic and/or hydraulic ejectors.

Bác cho em hỏi cái máy bay thế hệ 5 của Nga cũng có khoang vũ khí như F22 phải không các bác, em không hiểu tại sao Nga lại phải cho vũ khí vào trong bụng máy bay nhỉ .
1- Nếu máy bay có có khoang vũ khí để có khả năng tàng hình, điều này với F22 của mẽo sử dụng công nghệ lớp vật liêu và hình dạng để tàng hình thì điều này là đúng, nhưng với máy bay NGa ngố không sử dụng công nghệ tàng hình như kiểu Mẽo mà phát triển công nghệ tàng hình theo kiểu plasma chỉ cần đeo thêm một thiết bị bên ngoài nặng cỡ 100kg là máy bay tàng hình vậy thì cần gì phải nhét vũ khí vào bụng máy bay làm gỉ nhỉ, điều này làm chi phí gia thành sản xuất máy bay sẽ cao hơn, máy bay sẽ mang được ít vũ khí hơn.
2- nếu mà máy bay có khoang vũ khí sẽ nâng cao đưọc khả năng khí động học điều này đối với NGa cũng không đúng, dòng máy bay su27.xxxxx. theo các bác Nga thì khi mang đầy đủ vũ khí vẫn có khả năng khí động hoc tuyệt vời như kiểu bay cobra chẳng hạn.
Vậy em không hiểu sao tại sao máy bay Nga lại cần khoang vũ khí mà không dùng các điểm treo bên ngoài theo kiêủ truyền thống nhỉ .

Không lọai trừ là Nga đã thất bại trong nghiên cứu tàng hình plasma.
Tuy nhiên đặc tính khí động chỉ tốt hơn, tiết kiệm nhiên liệu hơn nếu đưa vũ khí vào trong thân, nên cải tiến được thì cũng nên làm.
Hoặc hướng nghiên cứu vật liệu RAM của Nga đã có thành công lớn, nên họ chuyển sang hướng này như một thử nghiệm.
Và trên hết, trông cái máy bay na ná F22 thì đối tác dễ chi tiền hơn
Hướng S-37 và 1.44 MFI hiện không rõ tình trạng phát triển. S-37 có vẻ sẽ thành chủ lực tương lai của Nga, vì vật liệu không dùng nhiều lọai cao cấp, khung dùng rất ít titan (so với F22 là 35% titan) - hợp với truyền thống vũ khí của họ!

Cho vũ khí vào trong có điểm rất lợi là supercruise, do thân hình nhẵn nhụi ít bị cản gió.
MiG31 động cơ rất khoẻ nhưng ko bay super cruise đc. SU27 cải tiến mấy cũng khó làm trò này, trừ phi phải sửa đổi thiết kế, như Su35BM.
Rafale, EF, Gripen có super cruise thì trừ phi bay ko hoặc đeo vũ khí đối ko tối thiểu, trong khi F22 bay full load.
Bọn Ngố thiết kế đc động cơ mạnh thì cũng phải xem xét chuyện này, nếu ko phí động cơ.

Jakarta seeks $1billion cre*** for Russian weapons
Jakarta is arranging $1billion cre*** with Moscow. The cre***, to be arranged between Indonesian and Russian governments, shall enable a hire purchase of an ad***ional quantity of Sukhoi fighters, and acquisition of a Project 636 class submarine. This is what Air Fleet was told at IndoDefence 2006 Expo and Forum held in Jakarta in November last year. The head of the Russian delegation Nikolai Dimidyuk said the respective agreement was agreed in general. Talks on the matter were held during the official visit of Indonesian president Susilo Bambang Yudhoyono to Russia in early December.
The $1billion cre*** is to be divided between Sukhoi fighters and Project 636 submarines in almost equal proportions. Indonesia is going to place an order for six fighters: three Su-27SKMs and three Su-30MK2s. The Indonesian air force wants more Sukhois, and seeks a ratio between single-seat and twin-seat fighters as 40 to 60.
Indonesia took delivery of two Su-27SK single-seat and two Su-30MKK twin-seaters in October 2003. These come with a limited weapons package. So far these have been used primarily for in-type conversion and training. The Indonesian air force has plans for a total of 24 Sukhoi fighters.
If Indonesia does go forward with an order for the Su-27SKM, it will become the first foreign user of this version. The Su-27SKM is an export variant of the Russian air force Su-27SM single seat air superiority fighter. The Russian air force has to-date upgraded about twenty Su-27s to the Su-27SM standard at the airplanê?Ts manufacturer KnAAPO when they underwent a major overhaul. The Su-27SM is basically an air superiority fighter with added strike functions. The latter include the capability to fire recent modifications of the Tactical Missile Corporation (TMC) Kh-25, Kh-29 and Kh-31 series missiles.
If Indonesia takes Su-27SKMs, these are likely to be made from airframes initially destined for China, but not completed as Beijing has been hesitating to finalize earlier agreed procurement plan for 95 ad***ional Su-27SKs. This agreement was a second part of the deal between Moscow and Beijing, under which China has already received 105 such fighters.
The Su-30MK2 will be newly built for Indonesia. They will be broadly similar to the Venezuelâ?Ts Su-30MK2s. Venezuela took delivery of its first two Su-30MK2s in December 2006. Caracas has placed an order for 24 such aircraft. It is understood that the Venezuela is taking the aircraft that were laid down at KnAAPO for the Chinese navy air arm. This batch was to be a second one for the Chinese air arm, but Beijing did not firm up this option as expected upon delivery of the first batch. In total, Beijing has taken delivery of 124 Sukhoi Su-30MKK/MK2 series aircraft from KnAAPO.
The customized Chinese Su-30MK2 can fire TMC?Ts newest Kh-59MK extended range (295km) cruise missile with active radar head. This weapon was developed for the Chinese navy on the base of electro-optically/radio guided Kh-59ME. China is understood to have procured these missiles. There are no confirmed reports about Venezuela or Indonesia having placed orders for these advanced weapon. The Russian air force is understood to be equipping its upgraded Su-24M2 interdiction aircraft with the radar-guided version of the Kh-59. First two Su-24M2 were taken by the Russian air force from NAPO plant in Novosibirsk in summer 2006, and four more in December that year.
The strike capability of the Indonesian air force will substantially improve with ad***ion of the new weapon. The Kh-59MK can be fired against surface ships, as well as high-radio-contrast land targets.
It also remains unclear whether Venezuela or Indonesia would take improved Vympel R-27P/PE.
This extended-range air-to-air missiles with a passive homing system is on offer in China. It can be fired from the Su-30MK2 and Su-27SKM. It is not clear whether the customers would actually go purchase this new version of the long-produced R-27 in the view that the more recent RVV-AE, a Russian equivalent to AIM-120 AMRAAM, is already a standard item on Su-30MKK/MK2 series.
Meanwhile, there is one thing known about the Indonesian preferences. Having compared in-service performance of AL-31F engines, the Indonesian air force has indicated its preference to those assembled by Moscow-based MMPP Salut. Today, two Russian companies, UMPO and Salut, continue series production of AL-31F series engines. UMPO supplies its products to NPK Irkut for installation on Indian, Malaysian and Algerian versions of the twin seat Flanker, Su-30MKI, Su-30MKM and Su-30MKA respectively. In its turn, Salut supplies its AL-31Fs to KnAAPO, for installation on Chinese, Venezuelian and Vietnamese Flankers, as well as Chinese J-10 fighters. The AL-31F series engines assembled by UMPO and Salut are interchangeable.
The Indonesian air force was in a unique position with two Su-27s powered by Salut-made AL-31Fs and two Su-30MMKs with UMPO-built AL-31Fs. Having compared the in-service performance of the engines from two manufacturers, the Indonesian air force chose the examples of the Moscow origin. It placed an order for replacement engines in second half of 2006. As of the time of IndoDefence 2006 Expo and Forum, three Indonesian Flankers were flying with Salut engines and a fourth was being re-engined.
Inspecting MMPP Salut stand at IndoDefence 2006 Expo and Forum Indonesian president Susilo Bambang Yudhoyono said that Jakarta wants to expand cooperation with MMPP Salut. Among programs being considered is trade-in purchase of higher-thrust AL-31FM2 engines producing 14,200kgf of thrust compared to standard AL-31F?Ts 12,500kgf and having extended lifetime, to 1,500hours. Other programs are training of Indonesian personnel at Salut?Ts Moscow site and delivery of industrial turbines.
Susilo Bambang Yudhoyono spent more time at MMPP Salut stand at IndoDefence 2006 Expo and Forum than on all other Russian stands combined. Most of the time the Indonesian president was asking questions and listening answers about the AL-31F-M1 engine. ?oThe president asked me very difficult questions, most of them technical?, - MMPP Salut general director Yuri Eliseyev told Air Fleet. ?oThese questions were quite intelligent for the man who does not work in this industry. On one side, I was pleased by the fact that the president of Indonesia devoted so much time to Salut products. On the other side, his questions were really difficult, as he demonstrated very a high degree of knowledge in aeroengines. He wanted to know how can we delivery the promised increase in thrust from 12500 to 14200 kgf, how does the jet nozzle deflection mechanism work, and what work shall be done on aircraft if standard AL-31F is replaced for the M1 version equipped with thrust-vectoring system. I get the impression that the president is very well aware of the technical matters pertaining *****-27/30 series fighters and their power plants?.
Indonesia is happy with the combat capabilities and in-service performance of Sukhoi Su-27SK and Su-30MKK fighters, as well their AL-31F engines, said Indonesian armed forces commander Air Marshal Djoko Suyanto. He accompanied president Susilo Bambang Yudhoyono as he inspected the Russian exhibition at IndoDefence 2006 Expo and Forum.

X-59MK missile
One of the latest developments of the SMDB ?oRadugâ? in the sphere of anti-ship guided weapons is the Kh-59MK air anti-ship cruise missile of extended range. The missile was first introduced at Moscow Aviation and Space Salon in 2001. This displays the further development of ?ogeneral-purposê? tactical cruise missiles Kh-59 comprising an element of Su-24, Su-24M, Su-30MK and promising Su-34 aircraft?Ts armament.
Unlike the predecessors (Kh-59 and Kh-59M) which had TV-guidance system, the new missile is fitted with active radar homing head ARGS-59E designed by ?oRadar-MMS? company from Saint-Petersburg. It?Ts capable of detecting ?odestroyertypê? surface targets with radar cross section of 5000 m2 at ranges of about 25 km and small patrol boats and missile craft (with radar cross section of 300 m2) at a range of about 15 km.
Another significant feature of Kh-59MK is high-efficiency bypass turbofan engine 36MT
developed by ?oSaturn? Scientific and Production Association, that replaced the former engine R-95-300 produced in Ukraine.The interchange of the launch booster by the fuel tank conduced to increase of Kh-59MK missilê?Ts maximum launch range up to 285 km (in comparison with Kh-59M?Ts 115 km). The bypass turbofan engine 36MT permits to launch Kh-59MK missiles up to 11,000 m. The missile passes the mid-course at a near-sonic speed at 10-15 meter altitude, which makes it less vulnerable to ship AD systems and fighters. Approaching a target Kh-59MK descends down to 4-7 m, as if it ?oglides over wave ridges?.
The new anti-ship cruise missile is equipped with the high-power piercing warhead weighing 320 kg (the heaviest of this type of missiles) capable of forcing out of action even such large targets as cruisers, fleet destroyers, oceangoing transport vessels; patrol or missile craft will go down even after the single hit.
Creation of the new ?oprecision-guided weapon? system is the toughest scientific and technical task that can be completed only in cooperation with various enterprises of the field as well as with government support. Development of the Kh-59MK missile has already gained the State-level support, in particular ?" the Ministry of Defense of Russian Federation, mainly owing to the fact that it is designed at the expense of the enterprises developing base-line systems.
Series production of Kh-59MK was started in 2005. The missile is expected to gain the considerable share of the Russian goods exported to the weapons market. It will primarily draw countries having in service Su-24MK and Su- 30MK capable of operating with Kh-59ME missiles closely related to Kh-59MK. Notably the Su-30MK can carry up to five missiles of this type. The design similarity of these missiles is to provide preservation of the current infrastructure of maintenance, repair services, ground handling and etc.
Besides, there is a possibility that after implementation of missile Kh-59MK into the anti-submarine aircraft Tu-142ME, delivered to India, retrofitted missile-carrier aircraft will be able to defy competition in combat efficiency with ones which have supersonic anti-ship missiles ?oYakhont-M? and ?oBrahMos?.
It is clear that Su-24M aircraft that are in service with the Russian Navy and Air Force
would require the new high-efficiency anti-ship cruise missile. As compared with foreign analogues weighing 500-1000 kg the new Russian anti-ship missile looks worthily. In particular, it leaves far behind most up-to-date US antiship missile Boeing AGM-84D Harpoon (launch weight ?" 63- kg) in range (240 and 285 km respectively) and in warhead?Ts yield (222 and 320 kg respectively).
The French missile AM 39 Exocet (launch weight ?" 670 kg) possesses much lower range (70 km) and carries only 150 kg of payload.
Modernization of its version equipped with a bypass turbofan engine and making range of 180-200 goes on, but there was no information on retrofitted Exocet in-flight tests. The latest Israeli anti-ship cruise missile Gabriel 4LR (launch weight ?" 960 kg) is capable of hitting targets at a range of 200 km. In the USA the anti-ship version of the tactical cruise missile Lockheed Martin AGM-158 JASSM is worked out (but still just virtually, on computer displays). Having 1024 kg in launch weight it is to possess about 350 km of range. All the above-mentioned missiles, as well as H-59MK, are supersonic, fitted with a radar homing head with similar indicators and fly at extremely low altitudes. Creation and startup of series production of the new, efficient, competitive and possessing promising export prospects missile Kh-59MK will contribute to strengthening Russiâ?Ts positions on the international air weapons market and increase efficiency of the national combat aviation.

Ngoài tên lửa không đối/ham/đất tầm xa như X-59MK Nga còn có Moskit , Yakhont , Brahmos và Club.Riêng Su-35 đeo được Yakhont và Club.Còn mát bay Su-30MKM mà bây giờ Malaysia có đâu 6 chiếc thì là bản nâng cấp của Su-30MKI và dùng được tên lửa Brahmó.
