Looks like it's just a quick cob onto an existing illustration to make it fit the situation. Not much sense to work on the tail that way and nothing much else.

Very curious to know how the engineers made it quiet.

This is a rendition of what it's thought to look like by a verbal description of a pilot. The helicopters that flew the Navy SEALs on the mission to kill Osama bin Laden were a radar-evading variant of the special operations MH-60 Black Hawk, according to a retired special operations aviator. The helicopter’s low-observable technology is similar to that of the F-117 Stealth Fighter the retired special operations aviator said. “It really didn’t look like a traditional Black Hawk,” he said. It had “hard edges, sort of like an … F-117, you know how they have those distinctive edges and angles — that’s what they had on this one.” http://www.airforcetimes.com/news/20...k-hawk-050411/ |

I am not sure how any helicopter can become stealthy....
three to six thousand Kg's with two engines, some blades trying to beat its self to death and the air into submission, sure htey can make they quieter and less audible, but stealthy..... the picture I saw of the crashed on against the compound all, the tail boom did look at bid odd though, like above said, flat sided etc etc Hay Ewe

That paint and angles could reduce the radar signature, but theres still enough for radar to bounce off. Maybe it has the "Turbo Boost" button like Blue Thunder and Air Hawk? From what little I have been able to gather, the word is the rotors are very quiet and apparently can't be heard until the aircraft is very close. So more rotors helps, but how do you stop the noise made from beating the air? Sounds very clever to me. |

I saw a thing on a Hughes 500 that was ultra-quiet...NOTAR tailboom, something about the main rotor blade shape. The thing was hovering a couple of hundred feet above the reporter...could barely hear it. I think it was a police chopper in California somewhere...

How are you supposed to keep control of the aircraft if the engine fails?

I would think if the stove quits the transmission would drive the NOTAR the same as it would a regular tail rotor.

Autos OK if you're light weight.
