radius than conventional aircraft. The massive control surfaces are capable of moving so far that they can completely destroy the aircraft in flight at high airspeeds if not kept in check by the FCS. Avionics The cockpit has three liquid crystal (LCD) Multi-function displays (MFD) along with a Chinese developed holographic head-up display (HUD), all of which are fully compatible with a domestic Chinese advanced helmet mounted sight (HMS), claimed by Chinese to be superior to the HMS on the Sukhoi Su-27 sold to China. Radar According to Chengdu Aircraft Industry Corporation officials the J-10 uses a multi-mode fire-control radar designed in China. The radar has a mechanically scanned planar array antenna and is capable of tracking 10 targets. Of the 10 targets tracked, 2 can be engaged simultaneously with semi-active radar homing missiles or 4 can be engaged with active radar homing missiles. For J-10B, the nose cone is modified to accommodate an active phased array airborne radar (AESA) radar. The general designer of AESA for J-10B is Mr. Zhang Kunhui (张昆辉, 1963 -), the head of 607 Research Institute in Neijiang, Sichuan. Mr. Zhang Kunhui became the deputy head of 607th Research Institute in 1997, and four years later in 2001, he became the head of the institute, when the AESA program for J-10B started. The primary contractor of this AESA is the Radar and Electronic Equipment Research Academy of Aviation Industry Corporation of China located in Sichuan, formed in March 2004 by combining the 607th Research Institute and 171st Factory together with Mr. Zhang Kunhui was named as the head of the research academy. According to Chinese governmental media, the AESA for J-10B took 8 years to develop, finally completed in 2008, and Chinese fighter radars hence achieved a quantum leap in that it went from mechanically scanned planar slotted array directly into AESA, skipping the passive phased array PESA radar. Many suspected the radar is a PESA, but during its brief debuts in the 7th China International Defense Electronics Exhibition (CIDEX) in May 2010 and the 6th International Conference on Radar held in Beijing in Sept 2011, Chinese official sources have claimed it is an AESA. Propulsion The J-10 is powered by a single turbofan. The J-10A entered production with the Russian Salyut AL-31FN. The initial version generated a maximum static thrust of . In December 2013, Salyut reported it was testing an upgraded AL-31FN Series
