Oh, so the AH-64E and Z-10 are the second picture with the whole sphere. I thought it was the picture with the sphere cut in two.
Whole sphere is probably correct though if you look at it from some distance since the DIRCM ‘eye’ is not flat on the wing tip. Two disconnected hemisphere would imply the eye is flat like paper and cannot see above the ‘horizon’ of the wing tip so to speak, which isn’t the case.
tbf that is most likely the case
so yeah the ideal implementation should be the 2 disconnected hemispheres
and that is a standard we should maintain…
otherwise… when the Su-57M is added… it will be immune to ALL IR missiles…
That’s not how it works though. You can see the DIRCM bubble from the front:
marked them in red. Blue is only correct if you stand below the rotor just in front of othe heli. Take some distance and both DIRCM will see you from full front approach.
i can also see the laser emiter and it will at most be able to gimbal until 93° until the wingtip will block it
also by the same logic the Su-27 and Su-30 should have 90° gimbal on their IRST
90 is more likely as the base of the emitter (the rotating plate) is a solid which doesnt exactly bend down
It seems like the eye itself is mounted on a rotating steel block which would seem like the most logical way to mount it to get full coverage. I might be wrong in this assumption but it sure seems like it. Good luck finding info about it though considering its classified.
Check my last post. The little block on which the eye itself is mounted rotating 180°(front to back) is all that’s needed to provide overlapping bubble coverage in frontal and rear direction. The only hole left on the coverage would be perfectly below, and perfectly above which sure seems a hell of a lot more logicale than leaving two giant deadzone in the coverage of the system.
which isnt enough for gaijin to model it as a full sphere even if we assume that it can gimbal up to 95° without being blocked
17ft 2in is 5.23m
and the 30m is an underestimation because in the wing span the LDIRCM wasnt included and i was quite optimistic with assuming it can gimbal up to 95°
yeah 90 seems to be the limit and even then its slightly clipping but i can chalk that up to modelling inaccuracy
So yeah, full overlapping coverage front and back as expected.
thing is, these systems are designed to protect against insurgent ambush SAM attacks. not from frontal and clearly visible ones. that job is for the pilots.
no
he says that it cant gimbal further than 90° of its standart position
uhh… i said 90 is the max…
which means 2 disconnected hemispheres but yes full coverage in their gimball limits
90° rotating from the standard position literally provide direct view on a frontal threat as long as you take some distance from the helicopter. I even gave you screenshot proving that where you can clearly see the sensors from the front.
direct view frontally but the spheres do not converge. hence there is a deadzone as wide as the wingspan of the Apache/Z-10
do you know what 90° are?
no matter how you puld it the coverage will not overlap
those lines are parallel to each other both 90° to the centerline (in the case of the apache the wingspan)
so please tell me when they will intercect
I doubt the model is accurate
as there is no reason for them to not extend it to have 92 or 93 degree glmble and have full coverage
Thank you I know what 90° is. The base on which the eye is mounted rotates 90°, then the eye itself provide a few more ° to catch the frontal threat from a distance.
To put it in other words, the base is your head turning 90°, and the eye are your eyes doing the rest. You only need a few degrees of additional of vision for the system to provide full overlapping coverage with enough distance.
irl there is a slight wall that further reduces (or increases horizon height) hence limiting it to (an optimistic) 90 degrees max
here, lemme show
this wall is not transparent and btw its not modelled too detailed in game
so now we get this as deadzone
