Stealth BlackHawk "leaked" is a mock-up

Posted on September 5 2012 by Julien Maire in BlackHawk, Black Hawk, Stealth Black Hawk

Mock-up of the Stealth BlackHawk (possibly used in a movie about the Operation Geronimo ?)

Is the one in the picture the fictional chopper used in the new movie or something else?

The Aviationist : David Cenciotti

Mock-up for 5 reasons :

- There is no antenna (even on the roof) !

... While a usual military helo have around 30 to 40 kind of different sensors & antennas.

- Blades fixation :

If you look at the blades fixations and pitches head, it seems to be a mock-up (such as EC175 model) and not a real one.

Some hydraulics are missing on the mock-up compared to te Main Rotor Head of a real Balck-Hawk.

- 5 blades :

I was the 1st that proposed the Stealth Black Hawk might have a 5-blade Main Rotor in order to use the noise reduction of this kind of rotor (see is my related post here)

... But after viewing and viewing again the picture showing the wreackage of the Main Rotor, I am quietly sure it was finaly a 4-blade only :

If you look at the main rotor, it seems to have 90° between pitches.

- Position of the Rotor Head :

As to optimize the noise reduction and avoid sources of noise, the Main Rotor Head may be as close as possible to the fuse roof (refer to the AS365 X 'DGV' and/or EC665 'Tiger' cases).

At least cowlings would have been added in order to both improve aerodinamics and reduce wind-sound.

- FLIR :

We can truely suppose the "Stealth BackHawk" are equipped with a FLIR.

And on the photo showing the [mock-up of a] Stealth BlackHawk, it does not seems to have one...

- Tail Rotor ?

... It is sad we do not have any photo showing the tail-rotor :

We could have checked if it is a 5-blade rotor (which is the case of the Stealth Black-Hawk) while some communities supposed it might have 6 blades.
