On February 20, the Chinese have the photos of the web performing speed runs modified layout fighter J-20 b / n 2011, reports janes.com February 23.
To speculate that this may be experienced benchmark tests focused on the PLA Air Force. First photo layout appeared in December last year. It is now clear that the upper edge is tapered down vozduhopoglotiteley engines keels cut on the top rear edge of the main chassis and niche compartments guns have more pronounced «teeth» to reduce the radar cross section, the canopy has a «peak» as the F-35.
By plane used a distributed system of infrared sensors, as the South American F-35, which reads about Chinese ambitions in this area optoelectronic technologies. It also shows that J-20 is a multi-purpose aircraft, having internal compartments gun huge size than F-35.
February 16 edition of the Chinese Securities Times Online said that the layout resettled latest version of WS-15 engines with afterburner thrust of 15 tons, the development of which can be completed in 2014. Other sources indicate that the establishment of turbofans can not be completed until 2020, the first production batch of J-20 will be equipped with Russian engines.
If so, the first serial J-20 will be equipped with engines AL-31F-M1 (Rod 13.5 tons), the AL-31m2 (14.3 m) or 117C (14.5 tons). In 2010, there were reports that China wants to buy 117C for J-20, but our homeland is in no hurry to sell these engines separately from the Su-35.
Tests of the first serial fighter J-20 engines c Russian production as part of the PLA Air Force could begin in 2015, delivery service in 2017 and the acquisition of initial operational capability by 2019.
Other sources believe that the double variant J-20S may appear later this year, which will compete with the two-seater multi-purpose attack aircraft J-16 development of the Shenyang Aircraft Company, which at the present time is tested.
But it’s unclear whether the latest pre-production layout. But it seems that the aircraft maker «Chengdu» withstand test schedule and production J-20. November 9, 2009 the PLA Air Force General Xu Veyron (He Weirong) has forecast that the latest generation fighter would be created during the «8-10 years.»
