Abstract: A method that includes takeoff of an aircraft assembly in a vertical orientation with a central axis X of the aircraft assembly perpendicular to the ground; rotating the aircraft assembly from the vertical orientation to a horizontal orientation where the central axis X is between ?5° and 20° from true horizontal; and flying the aircraft assembly from a first location to a second location in the horizontal orientation with an aircraft of the aircraft assembly generating forward propulsion for forward flight and a wing body of the aircraft assembly generating aerodynamic lift for the aircraft assembly based on the forward flight in the horizontal orientation, the aerodynamic lift generated by the wing body supporting equal to or greater than 70% of the weight of the aircraft assembly.

Abstract: A method of operating an aircraft including takeoff of an aircraft; transitioning the aircraft to a forward flight configuration by increasing an amount of forward propulsive force generated by a propeller assembly from equal to or less than 10% to at least 80% of a propeller assembly maximum and reducing the upward propulsive force generated by rotor assemblies from at least 80% of a rotor assembly maximum to equal to or less than 10%; flying the aircraft from a first location to a second location in the forward flight configuration; and transitioning the aircraft to a landing configuration at the second location by decreasing an amount of forward propulsive force generated by the propeller assembly and increasing the upward propulsive force generated by the rotor assemblies.

Abstract: A high transport efficiency aircraft apparatus for precisely delivering a payload at a target area without stopping is disclosed. An aircraft is adapted to fly at low speed and less than 10 feet above ground level over the target area, with a delivery trajectory including a steep descent toward the target area and a steep ascent away from the target area. The aircraft includes a payload bay constructed to contain the payload within the aircraft, and a payload release mechanism adapted to release the payload from the payload bay when the aircraft flies over the target area, allowing the payload to fall and arrive unharmed at the target area unaided by an aerodynamic deceleration device.

Abstract: An aerial vehicle including a collapsible and inflatable vehicle body capable of being filled with a lighter than air gas so as to make the vehicle semi-buoyant or 100% buoyant at a predetermined altitude in an atmosphere above a solar system body. The vehicle body has a shape suitable to provide aerodynamic lift. The vehicle may include a propulsion device coupled to and extending from the vehicle body, where the device provides power to aerodynamically lift the vehicle above the 100% buoyant altitude to a higher altitude where the vehicle can maintain that altitude through the aerodynamic lift and vehicle buoyancy. The vehicle is configured to be deployed/inflated from a collapsed and stowed configuration to a deployed/inflated configuration in an orbit above the atmosphere of the solar system body, and is configured to enter the atmosphere in the inflated configuration and descend without propulsion.

Abstract: The craft is for hovering flight, vertical takeoff and landing, and horizontal forward flight. It has a tail-sitting fuselage and a ducted fan mounted to the fuselage aft to provide propulsion in both (a) hovering and vertical flight and (b) horizontal forward flight. At each side is a floating wing, supported from the fuselage for passive rotation (or an actuator-controlled optimized emulation of such rotation) about a spanwise axis, to give lift in forward flight. The fuselage attitude varies between vertical in hovering and vertical flight, and generally horizontal in forward flight. Preferably the fuselage is not articulated; there is just one fan, the sole source of propulsion, rotating about only an axis parallel to the fuselage; and thrust-vectoring control vanes operate aft of the fan.
