    While this is no doubt make believe, X wing anyone?, forward swept wings faces a lot twisting forces,, its beautiful and slik! Love the look, of course you can get by with hinging the ailerons on an angle, but the stabilators being hinged as they are would result in tremendous airloads, you would of necessity align the hinge angle with the slipstream.

    Max,
    I am moving the conversation to this thread as a lot of what was discussed was cluttering the J-15 thread.

    I cannot vouch for the details as they are data specific to the equation. However the principle remain true and that is there is an underlying jamming advantage in terms of power requirement associated with a RCS advantage. The burn through threshold itself is condition specific as you would appreciate.

    With regards to the angular accuracy issue, it is a common problem especially with RWR.that historically had been pretty bad (10 degrees or more). There are recent advances such as with the ALR-67(V)3 on the F-18 that is down to 1 degree and the Spectra on the Rafael that is reportedly less than 1 degree. We don't know what the Chinese has but I do know that high end RWR/ESM with the high end capabilities cost. I question what one can buy when building a plane for $30 million. For example, the EPAWSS system alone planned for the F-15C cost $11 million plus a pop.

    Finally be mindful of triangulation conversation because the tech level required between a static target and a fast moving target are significantly different. It is a quantum leap in capability. Don't be blinded by a bunch of non relevant red herrings.

    I agree. Triangulation of a static ground target can be done by collecting several bearing samples spaced apart enough to overcome accuracy and noise limitations. The farther away the target is, the more spaced out the data collection points need to be, and therefore the more time is needed.

    The other exciting, and not mentioned component, are the real time computing resources that run the avionics control loops and actuators. These are undoubtedly highly customized.

    I watched Dojo explain his F-35 demos maneuvers, and the level of automation present in the aircraft is quite impressive.

    Transformable J-20X mecha/gundam? :D

    Can someone kindly translate the text in the photos?

    As a life-long model builder and diecast collector, I'd LOVE to know the price, date of availability & the name of the toy company. Thanks.

    This is a serious J-20 thread, and your post really has very little to do with J-20. Please post this under "Ask Anything" thread.

    What's the total number of aircrafts in the PLAAF?
