Recommended Posts

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.

Yes. It's true.

Well, is it modelled that way? That woud be interesting!

 

And does it distract missiles coming from behind better then (semi) frontal launched missiles?

According to Ironhand, ED has not modelled the warm-up time but is aware of it.

I'm glad it isn't modelled.

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.

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.

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.

Brilliant! It's funny you think you understand something but it turns out you've only got a very basic and mostly wrong idea. This is a good starter:http://www.ausairpower.net/TE-IR-Guidance.html
