Rotating wing assemblies for tailsitter aircraft

A vertical take-off or landing aircraft comprising:

• a wing support extending from an inboard region of the aircraft;
• a wing mounted on the wing support;
• a first propulsion system attached to the wing;
• and
• a second propulsion system attached to the wing;
• wherein
• the wing is positioned to rotate about an axis between a horizontal flight configuration in which the wing is generally aligned with the wing support and a vertical flight configuration in which the wing is oriented at an angle relative to the wing support, wherein the axis is positioned between the first propulsion system and the second propulsion system, and wherein the axis is oriented along a chordwise direction of the wing.

A vertical take-off or landing aircraft comprising:

• a fuselage;
• a wing support attached to the fuselage;
• and
• a rotatable wing section having an inboard portion proximate to the fuselage and an outboard portion distal from the fuselage, the rotatable wing section being rotatably attached to the wing support at a wing rotation joint and configured to rotate about an axis between a vertical flight configuration in which the inboard portion is positioned on an opposing side of the wing rotation joint relative to the outboard portion, and a horizontal flight configuration different from the vertical flight configuration;
• wherein the axis is oriented along a chordwise direction of the wing section.

A vertical take-off or landing aircraft comprising:

• a wing support extending from a main body of the aircraft;
• and
• a wing attached to the wing support, the wing comprising a root portion and a tip portion, the wing configured to rotate about an axis between a horizontal flight configuration in which the wing is generally aligned with the wing support and a vertical flight configuration in which the wing is oriented at an angle relative to the wing support;
• wherein
• the axis is oriented along a chordwise direction of the wing, and wherein the root portion and the tip portion are positioned on opposite sides of a center of gravity of the aircraft in the vertical flight configuration.
