That is pretty good, so my electret mike sound guided heli smasher design will need some adjustents.
Looks a bit like the tip of some bird wing.
Now sell anti-sound headphones to the enemy and it becomes undetectable :-)

Interesting find, but it should be noted that Eurocopter doesn't even
mention the word Stealth in their press release. It's all about the
environment:

"The aim of the bluecopter� technology program is to develop and
validate advanced technologies which offer environmental benefits for
new Eurocopter aircraft. This includes improved acoustics for lower
noise inside the helicopter and externally, along with a reduced C02 and
NOx footprint of the helicopter over its life cycle."

If you really want to build a Stealth chopper, your priorities should
be:

1) Reduce RCS
2) Reduce IR signature
3) Reduce acoustical signature

A technical sophisticated opponent will detect you on his radar long
before he has the chance to hear you. I have to admit however, that a
silent chopper would be very usefull against an opponent who is not
equipped with any electronic sensors.

Too close to Blue Thunder for my liking
