J-11BS is known as the twin seater version of J-11B. This is a multi-generation version 4.5 using more local components, including radar, engines and missiles. Aircraft based on Su-27SK/J-11 framework, but with the following modifications: - Using more composite materials to reduce weight and increase the life of the aircraft. - A multi-function fire control radar capable of tracking domestic 6-8 targets and combat simultaneously with 4 goals, the maximum range of the radar is 350 km. - A digital flight control system interior. - A systematic search of electronic and optical tracking OEPS-27 made â€‹â€‹in the form of Russia. - An inertial navigation system INS / GPS. - A cockpit features four multi-function color display (MFD) and a wide-angle laser image display (HUD). - Missile approach warning system. - Radar AESA, WS-10A engine The aircraft can carry short-range missile infrared led by China-made medium-range missile PL-8 and PL-12 positive self-serving war. While current Chinese Air Force combat capability with two goals combination Su-27/-30 and missile R-77 (AA-12 Adder), the integrated PL-12 success on J -11B will create the ability to combat many goals. J-11B is also expected to enhance the ability to strike the ground with the arms manufacturing precision bombing as LT-2 laser-guided bombs, dropping bombs guided precision LS-6, anti-radiation missile YJ-91, air-to-surface missile and KD-88. Specs J-11BS Crew: 2 Length: 21.9 m Wingspan: 14.70 m Height: 5.92 m Unladen weight: 16,870 kg Takeoff weight: 23,140 kg Maximum takeoff weight: 33,000 kg Engine: 2 Ã— Lyulka AL-31 F or Woshan WS-10A Maximum speed: Mach 2.35 (2,500 km / h, 1,600 mph) Range: 3720 km Combat radius: 2000 km Service ceiling: 19,000 m Wing loading: 371.0 kg / mÂ² Weapons: Guns: 1 Ã— 30 mm (1.18 in) GSh-30-1 Missiles (PL-12, PL-9, PL-8, Vympel R-27, Vympel R-73), Rocket, Bomb Maybe I do not need to say much about the Su-30MKI ! http://defenceforumindia.com/forum/indian-air-force/1363-su-30-mki.html Its strengths (J-11BS) compared to the Su-30MKI is the material is made of composites, should be lighter than the Su-30MKI and the angle of attack will probably large or mobility level will be raised, It is enough to compensate for the lack of 3D TVC or Canard, RCS smaller than the Su-30MKI as the Canard wing design.Engine 3D TVC (Su-30MKI) the only work effectively in Dogfight. Related to the radar of the two, India has now replaced most with AESA radar for the Su-30MKI, but it has the paint below the target detection range with PESA N011M Bars (300-400 km) I read somewhere that said AESA radar on J10B has a detection range of 200 km. However, if the information is correct, said that India replaced by Irbis-E radar on the Su-30MKI, which would be the advantage for India. We all know the winner of BVR will account for 90% of winning in the sky for today, so one has ever seen before shoot and kill the enemy before the most important, I think J-11BS with the supportKJ-2000 will be at the rate of 50/50. AESA radar frequency changes continuously, so RWR will not be able to detect, in addition to Su-30MKI can also advertise the operational independence not need to AEW, they make it as a mini-AWACS. Depending on the scanning angle of the radar and its scanning range.PL-10 missiles and R-77 probably will be at the rate of 50/50 for the 100km range (China also has R-77). The same rumors AESA radar (China anonymous) for J-10B and J-11B has a detection range of 200 km and scan angle of 60 degrees, AESA radar of India? I do not know much because is relatively little information. Also J-11BS has the advantage of being equipped with a maws (acting as a rear-facing radar), for melee / Dogfight some rumors that they develop a system flying hat (or helmet mounted displaysystem) allows the control of shooting, melee for with missiles IR seeker PL-8 (copy Python 3).
