BA-609 Display - Farnborough Air Show 2008

[strizhi]

That's pretty sweet - awesome wish I was there :)

[sbflash311]

According to Wikipedia, the plane is now the AW609. Bell has been bought out.

[necessaryevil101]

that looks very safe, very confident in the sky

[TheCosway]

I think your both nerds i just think its cool

[fordgt402]

Whats the top speed when in plane mode? How many times faster than the fastest copter?Its a cool craft btw.

[greenrice07]

@fordgt402 cruising speed during horizontal plane-like flight is approx. 300 knots.

[Arbitrage31]

If one engine fails dumb ass it burns half as much fuel!

[AxisAnalysis]

"Cool. But, what if... one engine should fail...? "

It has a transaxle that allows one engine to power both rotors in the event of a single engine failure.

[borbor122]

YUP YUP its ture

[KarthikSoun]

30billion dollars gone down the drain for something so small!!! Guess some one ate of the program!

[AxisAnalysis]

This is the civilian model, the military model is much larger.

[borbor122]

27 billion  in 20 years..... that is nothing compared to other military programs

[jesuitraiders]

Apparently the V-22 is unable to autorotate and I would imagine that this aircraft cannot either. Also on the V-22 there is a drive shaft that connects the props to the engines and each engine is powerful enough to fly the aircraft on its own. I would think that a civilian aircraft would also have that safeguard for liability reasons at the least.

[vijil]

Actually the V22 (and this one) can autorotate as well as most helicopters, and always could. The 609 also has the single engine ability.

[gianfryx2]

ye is safe, now is still in test phase in 2010 or 2011 will be get the certification by american civil aviation and italian civil aviation is developed by Itralian AgustaWestland and american Bell wioth a joint venture is for some aspect the minor brother of the V22 Osprey

[ryanmlt1]

Its called autorotation and this aircraft is capable of it . Its very safe safer then a standard twin engine aircraft.

[RoboTekno]

Epic

[mirasoltwins]

This plane/copter seems very maneuveurable.

[Dascoo]

WHAT IF ONE ENGINE FAILS ON A CHINOOK

[SheepJumpFish]

They have 2 engines that power rotors, not one engine for one rotor

[Dascoo]

NO I WAS BEING SERIOUS

[SheepJumpFish]

What? is that sarcasm because now you're just being unclear

[tsham511]

autorotr with the other, which is not possible with this type of aircraft, but they say it shouldn't happen in the first place..

[StewartBrasil]

Is this airplane safe???????

[Finalfire9]

micuronium haha i was just going to say that

[micuronium]

The engines are cross connected to a common gear box in the center of the wing, much like a posi-traction car differential. Thusly, if one engine should fail, both rotors will continue to have power, albeit reduced by half. This means hovering out of ground-effect wound be drastically reduced, but landing would be safe. Ground Effect is the cushion of air that increases lift as the down-wash of the rotor(s) is compressed against the ground. This begins at about 1 rotor diameter from the deck.

[noobie112]

Diameter.....or radius. (~!~)

[PieJesuG]

Pilot almost entered a vortex ring state in the video!

[jamesnewitt]

Anybody know what day this was ?

[cruzader0]

so many bald ppl in the stands:P 5/5

[guguigugu]

i like how the video makes it look like the blades are rotating really slowly.

must be a tricky aircraft to fly...

[yournameiswrong]

dont rate my comment a -1234567890

[r1994augusto]

if one engine fails....

I don't know

but i think that's why it has 2

[andynokia]

There's a driveshaft through the wing that connects both rotors, so one engine can still power both rotors.  Wouldn't want to test it though :-)

[PieJesuG]

If a helicopter engine fails the pilot is screwed too isn't he?

Atleast you can glide these down to the ground.
