摘要

Chengdu's J-20 stealth fighter represents the pinnacle of China's aerospace engineering, but its existence and development have posed mysteries since the unexpected appearance of the first prototype at the end of 2010, followed in May 2012 by the debut of a second, similar aircraft. The past few months, however, have seen the first flights of a pair of significantly different J-20s, identified by the serial Nos. 2011 and 2012. The most substantial design change in the new aircraft appears to be that the fuselage aft of the main landing gear is a bit more slender, with a deeper tunnel in the undersurface between the engines. The tailbooms that extend aft of the all-moving vertical tails are longer, and the lower fixed stabilizers are moved aft. The trailing-edge tips of the vertical tails and canards are cropped, and the leading-edge root extensions are straight rather than curved.
