Bin Laden Raid May Have Exposed Stealth Helo | AVIATION WEEK 'son' of Commanche? cool...... DM |
Its a tad tricky to make advancing blades stealthy!

Stealth is the wrong word. Low Observable. You cant eliminate it, but you can reduce it certainly.
|
No worries Sir, NFF. Good for the next wave.........
Stealth? My Ar$e! Low Flying at Night works. Also, there is that little known tacic of SURPRISE!!! Advo |
That's true of all stealth van rouge
Got to say that it is a very odd looking bit of kit, with it's swept horizontal stabiliser etc |

This shot shows clearly that it is five-bladed and that the blades themselves are quite different from those in the H-60 family as a whole. So, no, I don't agree that it's a standard four-bladed TR. http://img.photobucket.com/albums/v4...5_1303597a.jpg |
That's not like the S-70s I flew for four years.
I was quite diligent when doing the pre-flight walk-round but to be fair, it was very dark for some of the flights. |
I see no reason to think this is any member of the H-60 or S-70 family.
The tail rotor is entirely different with more blades and the fairing. The horizontal surfaces are forward swept and shorter. I think it's a newbie! |
|
Looks like some sort of lowsig S-76 to me... tail rotor hub is on the wrong side though!
|
No need for stealth - they could have painted them dayglo and festooned them with Xmas lights...
Or disguised them as tall Saudis...... |
You have my interest up, as I cannot recognize that lump ... wonder if anyone has the complete picture that came from.

The Wizard,
Only stealthy low observable helos that IIRC reminds me of 'Stingbat' plastic model Kit by Revell or Hasegawa released in the early 90s with extreme BERP like blades. It been based on the artists impression of proposed Bell Helicopter and the then McDonnell Douglas consortium for the LHX program with NOTAR. http://i57.photobucket.com/albums/g2...psea150557.jpg I had read a rumour that there had been a fly off demonstrator somewhere around the Nevada desert from Bell/McDH and the Army decided to go for the Comanche design (which hadnt flown till 96 anyhow). http://i57.photobucket.com/albums/g2...ell_lhx_01.jpg |

I've been desperately trying to mentally bend the rear of the 'SpeedHawk' to fit the article seen in the picture - other than a 5 bladed tail rotor - and stubby looking blades I cant quite manage it..
Thoughts? http://www.liveleak.com/view?i=70c_1242926443 |
That is definitely something new.
The stabilator is not a standard Blackhawk or PaveHawk, nor any other type reportedly used. There's a weird shield on the underside of the aft of the boom. And the tail rotor cap is very similar the main rotor hub on the Commanche. |
Ask the PLA, seeing in which Country this event ocurred I would not be suprised if the details of the remains are already being looked over at PLAAF HQ.
|
The photo's posted in the Daily Mail suggest a forward sweep to the Stabilizer and a bulbous fairing where the pylon meets the tailboom.
Then again I could have it the wrong way round! Osama bin Laden dead: Photo of Obama watching the Al Qaeda leader die on live TV | Mail Online |
Moderators, perhaps merge this thread with the 'other' thread?
|
Silent Hawk anyone?
http://www.militaryphotos.net/forums...hmentid=155097 No idea of provenance mind... |
Looks like the beast in question - good pickup. :ok:
|
A photoshop mockup based on the pictoral evidence (from Militaryphotos.net). Very well done though! - Some astonishing tripe being written about it (the mystery helecopter) too... Makes my 'night before' speedhawk conjecture almost plausible...
|
Yup.. that's the machine.. well spotted.
|
No it's NOT the machine...:ugh:
|
'Silent Hawk'. The clue is in the name. :hmm:
|
Would that size of TR be enough to control the Blackhawk?speedhawk or something of similar size...?

BBC report that White House is now saying there was a deliberate 25 minute video feed blackout during the operation. No one, unless they were there, saw what went on inside the compound.
Whatever next? :hmm: |
"The crashed helicopter's tail rotor bears more than a passing resemblance to that of the cancelled Boeing-Sikorsky RAH-66 Comanche "
Except for the fact that that it is in no way a fenestron? |
Hmmm, not a fenestron but in terms of the configuration of the individual tail rotor blades, their chord and length there is certainly a similarity with those of the Comanche.
This would tie in with the reoprted aspects of acoustic LO propoerties with the helicopter also.... |

Actually, what you are referring to looks a bit like the Main Rotor Hub (five bladed) of the Comanche. I am trying to understand who is seeing a forward sweep of the horizontal stab. In a hover, stab is typically 40 degrees down from the horizontal, in the S-70 class. I think perhaps the horizontal stab being in hover configuration is being seen in these photos as "sweep" of the horizontal stab. Or am I missing a few photos that show a real sweep? :confused: |
Nope, it definately has a forward sweep.
And fenestrons are totally different, and certainly in the case of the gazelle, not quiet! Is it just me that would love this to be an elaborate hoax from the yanks to throw everybody into a tiz and have the chinese/russions frantically trying to work out why you would have a forward swept stabiliser? |

I think he was probably referring to the Sikorsky system in particular BOAC as opposed to other such systems in general.
As for fenestrons being universally noisy - not true ( Comanche being a case in point). Perhaps more interestingly, did anyone else note that the fuselage seems to extend into an aerodynamic fairing that protrudes beyond the vertical stabiliser? |
I thought the whole point of the fenestron was to reduce the noise (and make it safer for those on the ground)
|
That's what I thought zondaracer. Did this aircraft have a fenestron? I haven't seen all the pics.
|
Hmm, certainly I was under the impression that the purpose of the fenestron was efficiency. ie good thrust from a ducted fan when required in the hover coupled with very effectively offloading in forward flight due to the shroud and tail

Here are 2 views of the 2nd Comanche prototype I took at on the first day of Farnborough 98
