Dude, blades doesn't emit heat that much. You should try to lock on the exhausts.

You can't make the same mistake twice, the second time you make it, it's no longer a mistake. It is a choise.

The blades don't emit any heat, in fact they are colder than their surroundings from all the wind chill they create. This is why on modern choppers like the Lynx Wildcat the engine exhaust is directed up into the rotor blades so the blades help to mast its signature, where the old Lynx doesn't.

But, but... They do.. I suppose it is caused by friction as they span across the air in such a high speeds, you can see it most clearly on the tip of the blades because it is the one traveling the most distance fastest, or then it is just the exhaust heating up the blades. I guess there are some materials used nowadays though to make the heat signature even lower, making the blades "invisible".

I dont have reference pictures, and I would think capturing such image would need some sophisticated IR equipment anyways, but I was able to find this:
Seeing in the Dark: Defense Applications of IR imaging | Optics & Photonics News

But then again, I also found this picture of boobies in infra-red:

There is also this nice effect which I remember seeing with the blades in sandstorm or something, as they swirl around they leave sparkles behind due to hitting dust particles.

I don't believe you, I think I'm gonna need more of these boobies in infra red pictures, and some in the visible spectrum as well please.

Terrific; thanks eddie!!

I tried that and first link on Wikipedia - no NH-90. Google image gives me the HIND used in PR (double seat) - not what I wanted. But thanks anyway.

EDIT: oh it was under the headline of MRH 90. My bad. Oh, and also I noticed why I skipped the NH90 - the wikipedia image made me think it was a German aircraft
http://en.wikipedia.org/wiki/NHIndus...ILA-2006_2.jpg

And oh, those who wondered - I ain't looking for credits. It's just I put in online to use as a cover page for my FB and wanted the designation in the description.

This was not shot by a phone. It wouldn't be that sharp; it was shot using a telephoto lens, specifically at 200mm zoom.

Case close
