[REPORTED] Pretty low IR signature.

[Airhunter]

I found that the JF-17 has a rather low IR signature from the front for most heat seekers. Is this value correct?

[witness_me]

how can you get the IR signature for aircrafts in dcs ?

[Airhunter]

Usually by how easy or far out you can get tone on your all aspect IR missile like the 9X or M.

[BlackPixxel]

Without afterburner it is similar to the F-16, but with afterburner the IR detection range is less than half of that of a Hornet (which equals to less than 1/4th of emitted heat). And that with a MiG-29 engine.

Would also be helpful if you specify exactly which ranges are the locks being aquired vs other jets.

 

Also please describe what weapons were used in the testing, which aircraft against which was tested and at what approach angles and altitudes of both jets.

 

Did you test each missile with different and same aircraft types.

 

With all this data, there might be something for us to debate on.

[shaHeen-1]

yeah even the Mig29/Su27 IRST is having trouble catching the Jeff.

What makes you think it is wrong?

 

Front aspect is pretty cool to begin with. JF-17 also has F-35-esque intakes.

 

If the jet is flown relatively slowly and not in AB recently, I don't think it is surprising.

 

There is more to IR signature than simply "it has the same engine".

[AeriaGloria]

I don’t know what the intakes would do for IR, they are supposed to help for RCS

[witness_me]

"Without afterburner it is similar to the F-16, but with afterburner the IR detection range is less than half of that of a Hornet" -- this doesn't seem like a valid comparison - why are you comparing with the hornet instead of another small single engine jet?

 

 

also, if you have dsi's you can't see the fan/engine from the front

[AeriaGloria]

You can see the engine from the front. The intakes even before they were DSI protrude a lot and hide the fan much more then a lot of planes, but with the right lighting there are a few angles where you can see the fan blades and vanes of the motor through the intake. It’s easiest to see in the model viewer with the flatter lighting

[witness_me]

fair enought it's not completely hidden, can we settle at "you can see less engine than without dsi's" (more bypass than core) ? That should have an effect on thermal signature would you agree?

[Harlikwin]

lord knows I've been killed my IR manpads more than anything else flying online, so I'm not sure its a real issue.

[AeriaGloria]

Witness I don’t think bypass and core have much to do with it, the front engine fan is compressing air both for bypass at the edges and the core towards the middle. Still won’t change IR signature that much I would think, but I’ve never stuck a FLIR in an engine intake.

 

DSI doesn’t help this very much when it comes to RCS

Retry sure it’s just there for stealth and simplicity to compete with X-35. Would’ve preferred a picture with the fan, but I’m sure Boeing marketing was very concentrated on avoiding having a photo in the public that showed there stealth fighter with titanium fan blades so near the front
