Abstract
A diamond quadcopter is described with tilting propulsion modules attached to a diamond faceted fuselage providing vertical thrust for Vertical Takeoff and Landing (VTOL) and transitioning to horizontal thrust for flight. The diamond faceted fuselage generates lift as a low aspect ratio lifting body. The diamond-like facet geometry enables propulsor placement to minimize interaction between the slipstream and fuselage in all modes of operation. A retractable landing gear with powered wheels allows Vertical/Short Takeoff and Landing (V/STOL) including emergency landings, and maneuverability on the ground. Landed and with gear retracted the bottom fuselage facet is close to ground level allowing an aft facet ramp for walk-on or roll-on access of passengers and payload. With the landing gear extended the vehicle can maneuver over cargo using the wheeled hub motors and then retract for insertion of cargo through a fuselage bottom door.
