OTHER: Aircraft - VTOL - AeroVantage - 1x2 Overview

• The use of a single transition mechanism; as opposed to the two mechanisms, which are proposed on the original 2x4 AeroVantage. This may result in a reduced concern about lateral asymmetric VRS, plus result in a more economical craft.
• The translation mechanism on this page consists a V-22 style rotation for the aft PropRotor and extendable arms plus rotation for the forward PropRotor.

• The fore and aft PropRotors will probably rotate (tilt) in unison with parallel disk planes so that there is a balanced thrust about the craft's centers. The front PropRotor's wrist will rotate through a slightly smaller arc then the wrist on the Rear PropRotor. They can also be independently rotated for maneuvering, if required.
• The elbow and the shoulder joints rotate in unison, with the shoulder rotating through a slightly larger arc than the elbow. The shoulder and the elbow will probably be mechanically interconnected to a common source of movement.
• The power for rotation may be electric or hydraulic.
• Transition Angles:

• Small UAVs; see 1682.html
• Small 1-4 seat manned craft
• Large transport ~ to compete with the V-22 Osprey

• For a single-man craft, the sweep-back of the wings moves the center of lift further back and this is good. Also perhaps Item1655 might be better for the Transition mechanism since it's rotors have a greater longitudinal stagger during hover. The sweep-back may provide greater stability and reduced drag at higher speeds? Winglets may also help.

• HeliWing ~ Boeing:
• 
• The Boeing Heliwing vehicle of the early 1990s. This vehicle had a 1450-lb maximum takeoff weight (MTOW) with a 200-lb payload, 5-hour endurance and 180 kts maximum speed and used twin rotors powered by a single 240 SHP turbine engine.

• Outside Craft:
• The flying wing is a 'wild' means of not having to pass a boom or twin booms past the large diameter pusher PropRotor. Perhaps Item1655 might be better for the Transition mechanism since it's rotors have a greater longitudinal stagger during hover.
