V-22 Osprey is a Go: Mass Production Approved

Looks like the V-22 Osprey will now be mass produced...

news.yahoo.com...

360 are to be built for the Marines, 48 for the Navy, and 50 for the Air Force.

Hope they prove worth the cost.

The V-22 is a good plane and will do just fine. Compared to other aircraft its had a better test record by far. Its just tainted because just one of the accidents killed 19 alone.

I am excited about this, I wonder how far off tilt turbojets are?

tilt turbo jets eh? sounds awesome. does anyone know if there are plans for one? Oh and happy about the Go for production been following the V-22 for awhile and its about time they went into full production.

I'd guess due to the inertial effects of the higher rotational rates in turbojets, along with the fact they are pretty inefficient at low speeds (essentially useless for vertical take-off/landing then) they will never be developed.

Even a Ultra-High BPR turbofan I don't see being developed, but a propfan is a possibility...

You ever seen the new GE-90's on the 777, you think those babies dont have low speed power, 130,000 pounds of thrust max, even at low speed, its so powerful, it will throw anything into the air.

Definitely nice engines those. But would the V-22 be able to hand the stress on the wings/tilt joints with that much power going through them? And what about fuel? Wouldn't that be a disadvantage since jets take higher grade fuel, and more of it to push the thing along?

Not to mention the Harrier uses distilled water to circulate to cool things down while it hovers. You'd have to add weight to have a cimilar system in a jet version of the Osprey.

Could someone present me the advancements that the Osprey V-22 has over the helicopters currently in service?

Apeed, flexibility, payload. Since they are airplanes, they can fly at 300 mph or so, as opposed to the super los speed of a helicopter. They can carry a bigger payload, and take off and land like an airplane, as opposed to helicopter mode, and they're big enough to carry a good sized number of troops.

V-22s are big right? Do they have the ability to land on frigates and destroyers?

They aren't THAT big. It's just that they have a long wingspan, and big rotor diameter.

If they CAN'T land it on a Frigate or Destroyer, they can sling cargo onto their deck underneath the fuselage.

Oh, about 40 years in the past!

Oh wow!!!! Bravo to the Germans, this again proves the superiority of German engineering (I'm biased towards German engineers, they are the best even though I'm not German).

What about the Bell (22?), the original US tilt(rotor)? Didn't it have 4 turbofans?

If you mean the Bell X-22, they were ducted fans, which are basically propellers with shrouds around them, ducted fans fans, turbofans and turbojets (which is what skippy was asking about) are all very different and the VJ-101 pictured above was the first tilt turbojet. The X-22 was not the first 'tilt -rotor' type however, it was beaten by a couple of years by the Curtiss Wright X-19.

The X-19 and the X-22 were both 'four poster' designs but the twin, tip-mounted tilt rotor design as used in the XV-15 and V-22 can be traced back to late '60's designs by Westland called the WE.01 and WE.02. The WE.01 was a small scale test vehicle directly comparable to the XV-15 whilst the WE.02 was to be a large transport, bigger than the current V-22. Being British however money, as always, was the problem and they remained unbuilt.

I'm not sure if a tilt turbfan has yet flown at all, anyone?

I have been flying it in my Real Flight Sim, out of all the planes it flies the best.

Thanks, Waynos, that was exactly what I was thinking of. Couldn't remember the details, I was just sure that I'd seen a picture of something that looked a hell of a lot like a til-turbofan to me.

If I remember correctly, they abandoned it because it wasn't stable enough.

I concur ,I have worked at Boeing's Military Helicopter Plant in Ridley Park since
1984.I have worked on The V-22 since that time ,In alot of Phases and even tho
it has had it's share of terrible times in testing and the real world . I also think in
the long run that it will be be a great AirCraft and Asset.

Moller SkyCar maybe?

The skycar seems to have ducted fans alright, but these are powered not by a turbine but a wankel engine (apparently).

The Heinkel Wespe also used ducted propellors, powered by a turbine.

I would expect the high gyroscopic forces of a turbofan the speed it would force a cross shaft to rotate at, and the fact it is not, and never will be the most efficient solution to the problem will mean it probably won't be developed. But hey, never say never I suppose
