Anyone has info on whether the ±70 deg in azimuth (for Bars radar) is with the electronic and mechanical steering combined, or just the electronic steering?
(Rosoboronexport AEROSPACE SYSTEMS export catalogue 2005)
There is this secondary source claiming ±90 deg but it also makes wild claims in terms of range:
(Russia’s Arms and Technologies. The XXI Century Encyclopedia. Vol. 10 - Aircraft armament and avionics)
For example Zhuk is listed to have ±70 with phased array antenna and ±85 for slotted array (mechanical) antenna.
Kinda doesn’t make sense for combined mechanical and electronic steering to result in less azimuth coverage than purely mechanical beam steering:
But then again, Bars’ ±45 deg elevation coverage (which is purely by electronic beam steering) suggests that it just has a relatively narrow beam steering coverage.
So likely ±45 deg coverage in azimuth with electronic beam steering and an additional ±25 deg with mechanical steering for a total of ±70 degrees.
Source?
Unless google translate is butchering it or I’m reading it incorrectly, the -14 elevation limit seems dog**** (and contradicted by the +45 deg listed in the export catalogue) and is that “3 to 10 degrees electronic steering in azimuth”?

-14 is not for azimuth.
For azimuth ±70 mech scan + 3-10 electronics scan.
For elevation it is from -14 to + 40 electrical stan.
What was the ‘T’ number for the Su-27SM that we currently have in game, as well as what Flanker it is?
For example, the base Su-27 is known as T-10S and as the Flanker-A (This is for the WTHLM Lang Mod)
If possible, a link to the source if you have it.
Yeah I meant -14 for elevation.
Seems really bad … Like I can’t understand how it can be this bad-level, bad …
BTW any ideas as for the discrepancy?
Rosoboronexport catalogue lists ±45 for elevation (purely electronic beam steering).
NIIP’s website also lists ±45 deg electronic steering (for the export version at least)

Don’t worry, that’s not quite true…

The first link makes me think that the -14 to +40 elevation and ± 3 to 10 deg in azimuth figures could be for some sort of ACM mode:
It’s flanker b not flanker a. Flanker a was prototype
Which standard Su-27 do we have? as there was many Flanker-As and 2 Flanker-Bs?
We have an flanker b (j11/su27sk and su27s) and a flanker e (27sm) although the 27sm that we have in the game never existed, it’s weird
So the Flanker-E Su-27SM doesn’t have an idz. T number? Even tho some sources say the SM was a mid life update for the Su-27
I sent it to you in Russian…Are you not from Russia? …
.the scanning area during the preliminary search and capture of a target in close combat, degrees:
And a photo of Irbis/Bars…
Look at the gimbal…A Bars has a larger antenna diameter, and it will not be physically able to turn 70 degrees…
So _40+30 degrees…
It technically never existed cause this is sort of a put together aircraft just so it can come earlier without its weapon of choice or some of its real equipment.
-14 to -15 is quoted but isn’t true, that is just for the close air combat vertical scan mode.
These radars have +/- 60 degrees vertical scan and up to +/- 120 degrees coverage thanks to electronic steering + mechanical gimbal limit. This is directly from Sukhoi, it is a primary source.
That’s for Su-35 though
N011M by most accounts (including official export brochure and the specs page on NIIP’s website has ±45 deg in elevation and ±70 deg in azimuth (45 deg electronically + 25 deg mechanically).
It is an example, the Su-35 is not the only aircraft that radar can equip. They gave Rafale AESA there is no reason to continue limiting the Sukhoi’s with lower end radars.
