Patent ID: 8894003

Claim:
An air vehicle, comprising: a body having a longitudinal axis; a wing rotatably mounted to said body with respect to said longitudinal axis, wherein said wing has a wing arrangement including a port wing portion and a starboard wing portion, and said wing arrangement is formed as a unitary wing structure; direction control arrangement for controlling the direction of motion of the body; and an actuation mechanism operable for selectively and controllably rotating said wing with respect to said body through at least a desired first angular displacement about said longitudinal axis, independently of operation of said direction control arrangement, wherein said wing is rotatably mounted to said body via a rolling mechanism, wherein said rolling mechanism comprises a sleeve configured for rotation about said longitudinal axis with respect to said body, and wherein said wing is mounted to said sleeve for enabling controllable rotation therewith about said longitudinal axis, wherein said wing is mounted in a substantially tangential relationship with respect to said sleeve, and wherein said wing is pivotably mounted to said sleeve via a pivot arrangement having a pivoting axis, said pivoting axis being substantially orthogonal with respect to said longitudinal axis, and wherein the wing is configured for being pivotably rotated about said pivot axis between a stowed configuration, in which a span of the wing is in a substantially parallel relationship with the longitudinal axis, and a deployed configuration in which said span is in a substantially orthogonal relationship with respect to said longitudinal axis.
