A J-20 fighter jet performed a rehearsal of the flight performance today at the site of the upcoming Zhuhai Airshow, according to a microblog posted by Chinese military blogger “Aviation Girl”.
From the photos taken, it appears that the J-20 is fitted with two Chinese-made Taihang engines, allegedly model WS-10C, which features serrated nozzles and once appeared in a propaganda video released by the Chinese Air Force in January.
