looks to me like the parachute door... in fact I haven't noticed the two hatches / doors open
Holy crap.
mean to write J-20 but I found a paper on the J-10 as wellHoly crap.
What's so holy crap about it?Holy crap.
Oh just that it’s a very neat paper that coincidentally goes into a lot of detail on the flight control law development process. May also have tidbits of data about key flight performance and operational parameters for the J-20 and other planes.What's so holy crap about it?
Just an observation, the wind tunnel model of J-20 without canard. This test was mentioned in 2001 paper 一种小展弦比高升力飞机的气动布局研究 by Song Wencong. However, this model must be much later than 2001 after the design has settled to be side mounted air inlet. In the 2001 paper, the proposal was belly mounted air inlet.
