J-15, September 9, 2009 manufactured the same year, was taxiing, the wings fold testing. But the authoritative source said: did not test flight in 2009. This trend may be related to the second batch of F-11B fighter aircraft by the Navy, the Air Force refused to receive information about. To be prudent, J-15 delayed the time to enter flight test phase. Open a number of sheets on the network to take off J-15 pictures, including a picture clearly see the front wing, although the picture is fuzzy, to forge such a fuzzy picture, it is very difficult. Can be sure that 33 F-15 is a Soviet clone of the letter. As we all know, the Soviet Union as the two-wheeled landing gear 33, a former design, frame straight, judging from the picture, J-15 also have such features. Radome coating different, the F-11B during flight radome color is black, the gray F-15. This distinction is necessary because different skills radar, as a naval fighter, F-15 radar, an additional air-to-ship weapons to the interface. The first F-15 aircraft is not clear whether the installation of radar, in general not necessary. Because the first aircraft flight control testing machine is mainly used for testing.
Su-33 with 14 degrees the ski-jump take-off, it was shortened caudal, F-15 are identical. The current conclusion: China is clearly through the Ukraine, not only made T-10K testing machine, and most likely made the maintenance of T-10K drawings, simply copy T-10K airframe.
Change color from light green body color judgments, F-15 composite materials used in roughly J-11B, F-11BS same, especially in the vertical tail, the wing part. Su-33 because it is developed in the late 80's, the last assembled in 1992, so only a very small amount of composite materials. So, J-15's empty weight is lighter than the Su-33. Aircraft thrust-weight ratio greater results, means that the increase in load of bombs.
May this year, Shenyang Airport found a more flat fan of J-11B flight. F-11B test flight in 2009 because the tremor occurred, but was rejected by the Air Force. The new flight display: Shenyang plant seems the second installment of the original F-11B has been improved. F-15 flight test means that the plant is restored to the technical problems to some extent self-confidence.
Authoritative sources, the F-15 still use the Russian AL-31F turbofan engine. As a new aircraft, with the new engine at greater risk.
Imports only from T-10K testing machine, manufactured in 2009 the first F-15 aircraft, just less than five years, indicating China's cloning technology was exceptionally high. If the aircraft materials, radar, avionics technology will not reach the stage of independent technological development, can not be cloned. Even if the U.S. aviation industry Kelong Su 33, may also require considerable time.
In the next five years, a new generation of F-11B, J-11BS, J-15 are likely to become more mature fighter volume production; F-15 flight test to finish, probably around 2012, provided that the continued use of Russian engines . 2013-2014, F-15 may enter the production phase. It is fully able to catch up with the progress of China-made aircraft carrier production.
