1) Is there any significant distance between the vertical taking off range of Osprey and traditional taking off range? Like the gap of range on Harrier being VTOL and STOL

A loaded Harrier needs 400-750' or so of runway to STOVL depending on the runway: flat or ramped at the end; V-22 can take off either vertical or STOVL as well. However, the Harrier can't carry up to three dozen soldiers.

2) Is it possible to makes engine nasele lean to rearwards a little bit so that the Osprey are capable to fly reversely like a traditional choper?

Yes. They can rotate approximately 2.5 degrees over vertical which would allow some rearward motion. Additionally, the rotors on the Osprey have swashplates similar to a helicopter thus can manouevre similarly: fore and aft, lateral motion (to the sides) as well as being able to yaw 360 degrees while hovering.

3) Is it save enough or is it hard to fly Osprey due to a basic geometry principle, which is three points determine a plane.
Well, normal helicopters have only one main rotor and they fly. The Osprey may be a bit more difficult to fly due having two rotors at the sides of the craft, and the different controls between helicopters and planes, but that's what avionics are for.

4) Is the Osprey truly successful according to its flying envelop cover the propeller airplane and helicopter to both but reluctant?

It's a helicopter and plane combined thus can travel faster in level flight than a helicopter and can take off and land vertically which a traditional airplane cannot do. It's hard to say at the moment whether it'd be successful or not but it would likely be of benefit to any operation requiring relatively quick transport of a moderate payload, equipment or personnel, into and out of an area unsuitable for airplane landing. I suppose a joint helicopter / plane mission could be planned but sounds a bit more involved logistically speaking.

Hi Emile,

www.g2mil.com...

I have been reading about this particular 'project' since high school and it did not take particularly long to find not only criticism ( you can always find that) of the tactical/strategic viability but quite a bit related to just how badly this idea has been implemented. Flying this thing anywhere near to where shooting is happening is a sure fire way to get everyone killed ( or at least risking lives American generals hate losing in these little non wars) and flying it at any other time simply does not happen often enough to make this a practical replacement.

I am fairly sure that it has so far killed more Americans, i think 34, than terrorist/insurgents( whatever; killing that could be accomplished with less risk) and while i hope that it does not continue to do so if it's used in the way it was claimed it could be it's going to kill many more Americans and the only way to stop it doing so will be to use it like C-130 which not only cost less and carries 6 times as many troops over ten times the range at close to twice it's operational speed but does so ridiculously safely. In fact hot landings with the C-130 would probably be safer and given how that airframe has been modified over the years i reckon you could make the landing as hot for whoever is waiting in your typical brush non-war scenario. Given the modest crew requirement( say 20) you could armor the aircraft to make it's crew and assault troops quite safe from small arms/50 cal fire and lay down significant fire if it's cheaper to do so than having dedicated escorts. I mean i don't seriously suggest we try this but I'm am just saying that it would be more practical and probably no more costly than your typical airborne/parachute often-suicidal-type assaults and still less ridiculous than the V-22.

If i had plans for world domination this is the sort of contraption i would pray my adversaries spent their resources on.

The service record of this aircraft differs from other rotary and fixed wing designs... how?

We lose more troops to accidents in the supply lines supporting front-line troops than we lose of the front-line troops.

From when I was about ten years old, until about fifteen, I couldn't turn on the news without hearing about some Black Hawk or Chinook going down in some place the map forsook.

Just by giving the order to deploy people - a certain percentage of them are, statistically, going to die. Most of it due to maintenance oversights, accidents, and failure to apply ORM (Operational Risk Management).

The V-22 deserves very little of the bad press it gets. Statistically, it is a safer airframe than just about anything else in service and a better survivability rate (though that could be like saying a fuel truck is more statistically survivable than an M-1 tank - you don't generally expose a fuel truck to the same things you do a tank). The accidents it is going to have by the raw nature of probability are then inflated because it is a 'revolutionary' design. People wonder about how safe and effective it is - since we don't have videos of it flying in, kicking ass, and taking names - we get to have our fill of drama off of the accident reports.

We never really get out of highschool. We all crave drama, and that's all the claims against the V-22 amount to when you stack it up side-by-side with any other machine out there. At the end of the day - it's about ten times more reliable than your car even when it's sucking in sand for three months and over a hundred flight hours past component tolerance ratings.

Developing it has been expensive - I'm not going to defend or attack that point. It merely is what it is. As for whether or not it's been cost-effective... again - it is what it is. Once you're committed to a contract and the need for an airframe to fill a role, you're committed. Stopping at 10 billion dollars as opposed to the alleged 30 billion would have netted us... what? 10 billion dollars and no V-22 with a hole in the arsenal (you could argue that there's not a hole there, but, it's a role that will no longer be capable of being utilized in any strategic plan).

It's an issue of opinion, in that case. I see the craft and mission as more important than the arbitrary cost. I can hound defense contractors for their handling of their responsibility that drives up such arbitrary numbers, but at the end of the day - it's the plane/tank/etc that you want and need. Costs - unexpected or planned, are to be encountered.

I'm not a fan of the way the F-22 was horribly abused. What was worse was deciding to not complete the arsenal. You can't be whimsical about selecting and establishing an arsenal. Once you commit to it - you've got to see it through. Same with things like the V-22. The C-5 was worse - all kinds of stuff, such as $20,000 'special' hammers that "do not damage the aircraft" - that should not have been.
