R-2 Heavy lift gyroplane
http://media.popularmechanics.com/images/tb_groen1-lg.jpg
The The Bellamy Aviation Co. Rotary-2 gyroplane was originally meant for civilian uses. However, the Soudinese military was interested in acquiring it for use in the Army and Marine Corp. It replaces the Soudinese variant of the ancient Chinook helicopter. It carries a larger payload over greater distances and is faster than the Chinook.
Rotor Diameter: 130 feet
Payload: 50,000 lbs
Length: 145 feet
Range: 1000 miles
Max Speed: > 290 mph
Armament: 2 x 7.62 machineguns
Cost: $25 Million
This aircraft has not yet been cleared for export.

OOC: Why not just use the Osprey? Or a working Osprey. Not to mention it would probably suck up alot of fuel with so many damn engines having to power the rotarys.

Not if the same engine powers 2 or 3 rotars
For how the picture looks it looks like it goes 2 rotars to an engine
And the B-52 has 8 turbojet engines so talking about fuel sucking

OOC: The Osprey is a bit shaky in the reliability department. Also, this thing has a greater range.
The cost in fuel is greater, but so is the speed and range.

From the looks of the rotor tips it looks like it uses tip jets to power the main rotor in the same way the 1950s/60 Fairey Rotodyne did.
basically during lift off the propulsion engines (the turboprops) have a secodnary job of pushing compressed air up into the blades of the rotor. This compressed air then rushs out vents at the end of each blade and is ignited (not always though it depends on the aircraft) driving the blades round at reasonable speed.
Once the aircraft enters level flight the tip jets cut out and the rotor begins to auto gyrate generating huge lift and granting rahter impressive effiency benefits.
The gyrodyne/rotdyne/gyropalne idea was fully developed in the 60s and the previously mentioned Fairey rotodyne out perfromed the chinook in every aspect, unfortuantly the british govenrment was in the process of destroying the UK helicopter industry at the time and ordered the project cancelled on cost and noise grounds (the rotodyne wa sa bit noiser in early versions but by the time the cancellation order came they ahd pretty much brought levels down to acceptable levels).

Yeah, that's it. This one is actually based on the Groen Gyrolifter, but the Rotodyne was the original gryoplane.
