plagiat Posted May 8, 2005 Share Posted May 8, 2005 i found something interesting about Sukhogruz... notice warm-up time, please - 5 min :confused: L166 L166BIA Airbome fixed-source infrared jammer. The L166BlA comprises a 365 x 463-mm transmitter- radiator unit which weighs "no more than 20 kg" (weight and size of the "lantern" varies according to the needs of the particular platform the figures quoted relate to the Mi-8 application) and a 95 x 70 x 45-mm, 0.125kg cockpit control box. The L166BIA is quoted as offering protection against a range of threat missiles such as the Sidewinder, IR Falcon, Mica, Strela 2M, Redeye and Chaparral. Specified system life is 1,200hr with a "time between failure" value of 250 hr. Infrared source life is noted as 50 hr. Sukhogruz on the Su-25T L166SI Sukhogruz 6,000W Caesium lamp active IR jammer mounted on Su-25T. Warm-up period 5 min. Modulation frequencies: 8 channels between 700-1,700Hz at 100-150Hz separation. Weight is 28 kg (transmitter), 3.5kg (control unit). L166V-11E Ispanka microwave IR jammer on Mi-24. Proved useless against modern MANPADS in Chechnya.

ED Team Chizh Posted May 8, 2005 ED Team Share Posted May 8, 2005 i found something interesting about Sukhogruz... notice warm-up time, please - 5 min :confused: Yes. It's true.

JaBoG32_Prinzartus Posted June 16, 2005 Share Posted June 16, 2005 Well, is it modelled that way? That woud be interesting! And does it distract missiles coming from behind better then (semi) frontal launched missiles?

ZoomBoy27 Posted June 16, 2005 Share Posted June 16, 2005 According to Ironhand, ED has not modelled the warm-up time but is aware of it. I'm glad it isn't modelled.

coldcrew Posted June 16, 2005 Share Posted June 16, 2005 Well, is it modelled that way? That woud be interesting! And does it distract missiles coming from behind better then (semi) frontal launched missiles? it only works from behind. You'll get no love from missiles coming front or side. Try the last training mission on ECM and missile evasion (it says it's a su27 mission in the brief but it's actually a su25T). Halfway through there is a flyby over some strelas showing it actually works. Link to comment Share on other sites More sharing options...
Woodhouse Posted May 12, 2017 Share Posted May 12, 2017 I'm intrigued as to how this works. Surely it's just going to look like a big IR source which is only going to make matters worse? A google search only shows this thread. Oh and good morning everyone. This is my first post and I'm quite new to DCS. M. Link to comment Share on other sites More sharing options...

GGTharos Posted July 8, 2017 Share Posted July 8, 2017 OMG, your first post and incredible necropost :D The way this works is a bit like a disco-lamp, and it has to do with how the missile seekers work. By sending specifically timed pulses it sets up a harmonic with the spin cycle of the seeker (it has some spinning components), and causes problems with correctly detecting target location. If you search for 'nutating IR seeker' or 'reticle seeker' you might start finding some documents that will help you understand this better. I'm intrigued as to how this works.

It's funny you think you understand something but it turns out you've only got a very basic and mostly wrong idea.
