Rotary-wing air vehicle and method and apparatus for launch and recovery thereof

A rotary-wing air vehicle comprising a main body, and at least two rotor devices arranged and configured to generate propulsion and thrust, in use, to lift and propel said air vehicle, said rotor devices being arranged and configured relative to said main body such that the blades thereof do not cross through a central vertical axis of said main body defining the centre of mass thereof, wherein said main body is provided with an aperture that extends there through to define a channel about said central vertical axis, wherein, in use, the aperture is arranged to receive an elongated pole member;

• and
• a pair of opposing wing members extending substantially laterally from the main body, each said wing member defining a longitudinal axis, at least a first propulsion device associated with a first of said wing members arranged and configured to generate a linear thrust relative to the main body in a first direction, and a second propulsion device associated with a second of said wing members arranged and configured to generate linear thrust relative to said main body in a second, substantially opposite, direction such that said wing members and said main body are caused to rotate, in use.
