Thrust Vector Engines for the J-10 and Carrier News
Russian sources stated that China and the Russian Salyut engine concern were in the process of negotiating a future sale of the AL-31FN engine, but with a axisymmetric thrust vectoring nozzle
. These sources would not state the number of engines in this package, but did confirm previous statements that the thrust vectored engines were intended to support a Chinese Navy version of the Chengdu J-10 fighter--presumably for aircraft carrier use. In 2005 a Russian source had noted China’s interest in the thrust vectored modified version of the AL-31FN, but in 2007 it is now apparent that such a sale is under negotiation. With its forward stabilizer “canard” configuration, thrust vectoring for the J-10 could conceivably allow a lower landing speed, or enable a faster recovery take-off from a “Bolter,” or a failed arrested carrier deck landing. Both capabilities would be of interest to the PLA Navy to increase operational safety. In addition, other sources indicate the PLA will use the thrust-vectored J-10 version to better enable useful payloads to be lifted from the high-altitude bases of the Tibetan Plateau just north of India. Otherwise, thrust vectoring would add more to the already inherit high maneuverability of the J-10’s canard configuration. Russian sources claim that the thrust vectoring nozzle will not add additional weight to the engine, which might then require airframe or ballast modifications for aircraft. http://www.strategycenter.net/research/ ... detail.asp
China Signs $500 Million Russian Jet Engine Deal, Vedomosti Says
China’s Ministry of Defense signed a contract to buy Russian aircraft engines worth $500 million in early June, Vedomosti reported, citing an unidentified personsource close to Russia’s state arms-selling agency and an unidentified manager of an aviation company.
The contract is for 123 AL-31FN engines by 2013, the first 13 of which will be delivered later this year, the newspaper said.
