    Again, no disagreement. But for a system of this sort of flight dynamics(such as Ra'ad) , you may not need to go too much in depth. And yes, unlike Pakistan a lot of research in India is transparent; something that is both good and negative.
    Good, because it ensures a high level of secrecy as to what is going on.. and bad..because many a good engineer is left unable to state their accomplishments to the fullest.

    You mentioned SOM for influence and then mentioned "for shorter range" a C802. You said "as for short range ALCM" like SOM was something else. The range of both is somewhat same. They will fall in same category as far as range goes so what am i missing?

    That is a TERRIBLE idea lol. But you knew that. Control engineers should be kept in the loop from the start even though sometimes they aren't.

    Ok so it is not that C802 is "for shorter range ALCM" they both are both are!! However since the technology is different (sources are) so both interests you individually. Makes sense now. :) :tup:

    Yes i know man and believe me thats not really a productive method of designing,but that is how aerospace research is conducted in india.A more balanced approach would be to incorporate control engineers right from the beginning. And Aerospace Control is perhaps more demanding vis-a-vis traditional application of control theory like controlling a reactor,heat exchanger etc etc because of the fact
    1)That it is highly non linear! It gets a bit tricky to get answers that converge- especially when you're trying to use optimal control theory.
    2)that an aircraft is desired to operate at multitude of equilibrium points(in contrast to this boilers,reactors etc operate at only one or at max a few eq pts).This means linearization of NL eqns around those points-but this might sometimes give mis-leading answers as to what really happens around that point- for instance around "centers","non-isolated fixed points","star" or other degenerate cases
    3)Control Engineer must also ensure stability of these equilibrium points and how they behave using bifurcation theory and branch-continuation.Thats where auto07p like tools come in handy.hint flutter,wing drop etc etc

    pick your favourite. see what the turks have and get it same applies to china and use it where usefull. but the c802 is the obivous choice you pakistan since its in use, but them som would be preferable, as it means the turks will help with mini turbo engine development as they are making an engine to replace the tri-40 also they have a varient that can fit internally in the f35 so that may be usefull to pakistan when it gets its own 5th gen fighter. thinking ahead is the aim of the game here

    Yeah yeah i understand all this detail. Was just confused when you mentioned C802 as "for short range" as if SOM was any different in terms of range. It is understandable how they offer different technology insight. :tup:

    Great thread, topics like these reflect the spirit of what this forum should be known for. Kudos, @JamD !

    As I said previously, since I don't have much knowledge of both Ra'ad's dimensions and JF-17's hard-point limitations, I cannot comment on it with certainty. But what I am certain of is that both the strategic planners of these weapons systems and their end-users are aware that Mirages will be phased out, sooner or later. Therefore, Ra'ad will be made compatible with JF-17s as it is going to be the main workhorse of PAF.

    Right now, IMO either of the following can be true:

    1. The analysis regarding the dimensions of Ra'ad is a bit flawed, the author might have overlooked some critical parameter. Ra'ad in its present form poses no problems for JF-17 integration as far as physical parameters are concerned.
    2. The analysis is correct, however an easier fix in the form of fold-able fins will solve the problem.

    P.S. those who believe JF-17 will not assume strategic roles are gravely mistaken.

    Even the existing 800l centerline tank has very low clearance the only effect is low AOA for take off if there are no other issues

    Secondly the Raad intake protracted out during flight/launch and not during carrier carrying it before launch
