MRCA J-20 was the highlight at China International Aviation & Aerospace Expo

The 12th China International Aviation & Aerospace Expo (held biennially at Zhuhai in southern Guangdong) that kicked off on November 6 and closed on the 11th, played host to a wide variety of guided weapons employed for asymmetric warfare, as well as new-generation mission avionics for air combat aircraft platforms, plus the ever-growing types of homegrown unmanned aerial systems (UAS).
However, the expo this time will be remembered for the J-20 emerging in full-blow, since the People’s Liberation Army Air Force (PLAAF) was authorised to ‘de-classify’ this multi-role combat aircraft (referred by China as a fourth-generation homegrown platform) for both flying displays in fully armed configuration as well as a full-scale indoor exhibit mock-up. Four J-20s came to deliver flying demonstrations for four days on the 6th, 9th, 10th and the 11th (a fifth J-20 was on standby at the dual-use airport in Foshan in the Pearl River Delta), with the last day also being the PLAAF’s 69th anniversary. Lt Gen. Xu Anxiang, the PLAAF’s deputy commander, revealed on that day that the demonstrations were indicative of the J-20s having attained Initial Operational Capability (IOC).
Leading the presentation on the J-20 was Yang Wei, Chinese Academy of Sciences academician and chief designer-cum-engineer of the J-20 (under Project 718), who was backed up by Chief test Pilot Li Gang, the winner of the PLAAF’s ‘Golden Medal of the Meritorious Flying Personnel Medal of Honour’. At 15 years, Yang became the youngest student majoring in aerodynamics at the Northwestern Polytechnical University at Xi’an, in northwest China’s Shaanxi Province.
In 1985, Yang graduated with a master’s degree and joined the Chengdu Aircraft Design Institute (CADI), which is owned by the Chengdu Aircraft Industry Group (CAIG) in Chengdu, Sichuan Province. For the next 30 years, he participated in and led the design of a series of homegrown combat aircraft including the J-10 and FC-1/JF-17. Yang’s first task after joining the CADI was to participate in and later lead the development of digital fly-by-wire flight controls. He also implemented all-digital simulation tests for combat aircraft. In 1998, 35-year-old Yang was given the task by Song Wencong, then the chief designer of the J-10, to fix the J-20’s design problems, optimise its design and complete its certification of airworthiness. Two years later, at 37, Yang became the youngest chief aircraft designer in China for both the J-20 and the FC-1/JF-17 light multi-role combat aircraft (L-MRCA).
Li Gang revealed that at least five rounds of review and selection took place of the J-20’s design optimisation. From the plan on paper to the wooden model, then to the metal model, the participating engineers and test pilots worked on the slightest details, especially in the arena of cockpit ergonomics. The end-result was a cockpit with one principal frontal panoramic active-matrix liquid-crystal display (AMLCD), two side-mounted AMLCDs, and two sidebar-mounted controls — a first in China — one for throttle and the other being the control-stick.
