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.
