Do we have a timeline or updates on the Ws-15 engine. Some report claimed a max production rate of 5-6 engine per year (way to limited).
That's overly simplified.
The Meteor uses a seeker of the same family as the MICA and ASTER missiles and is a known and proven technology.
Also no aircraft is gonna fly straight into a missile while hoping it can jam it successfully - we will gonna see F-pole engagements which the ramjet will create a no-escape zone way larger than the Chinese PL-12 and PL-15 capacities.
Posted previously, but given that it's hard to search for, it's not a big deal. Note that the "fixed" J-20 canard set-up is far different from the canards implemented on the J-20.Highly recommend reading the papers published in the latest issue of the Chinese Journal of Aeronautics, many are related to J-20's R&D, including the once-hot topic, do canards affect the stealth capacity of J-20?
The abstract:
This paper studies the Radar Cross-Section (RCS) effect on canard configuration fighter of canard. First, the scattering mechanism of canard is analyzed. And then, the Multi-Level Fast Multipole Method (MLFMM) is used to compute the configuration’s RCS of the given fighter models. And by comparing the computational results of both the canard configuration and the conventional configuration, the RCS effect of canard is analyzed, focusing on the RCS effect on fighter after the canard is rotated. In addition, a full-size parts stealth test is conducted by researching the RCS effect on fighter of both edge scattering and gap scattering and respective inhibition measures. The test results show that, after the scattering of canard is inhibited, the RCS level of canard configuration can be applied to configuration design of stealth fighter. And its stealth capacity is comparable with that of the conventional configuration. Finally, the guiding principles of canard stealth design are postulated.
But still, it would be a nice read to understand how canards would impact the overall stealth, and you can have a general idea on how canards might impact on J-20 despite some differences. Overall this paper is about the principles and overall rules of canards design impacts over aircraft stealth. It was also discussed previously...Posted previously, but given that it's hard to search for, it's not a big deal.

sorry, but which chart you are referring to? I can't find any chart imply a 2.5-5 dBsm penalty for canards?The charts roughly imply a 2.5-5 dBsm penalty for canards, although there's definitely regions where the canard layout wins out vs a conventional layout. It's just that the canard stealth angles are different than tailed stealth angles, so that's a factor that has to be considered; i.e, can you keep your canard stealth fighter at an advantageous angle vs a tailed emitter, while keeping them out of their advantageous angle?
