Interesting catch...........
and now we hadThrust Vector Engines for the J-10 and Carrier News
January 20th, 2008
Richard Fisher, Jr.
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 (this came at a time where J-10B was in development and there was no news of J-10AH) --presumably for aircraft carrier use. In 2005 a Russian source had noted Chinas 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-10s 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.
