Abstract: An air vehicle is provided, including a body having a longitudinal axis, a wing arrangement rotatably mounted to the body with respect to the longitudinal axis, a direction control arrangement for controlling the direction of motion of the body, and an actuation mechanism operable for selectively and controllably rotating the wing arrangement with respect to the body through at least a desired first angular displacement about the longitudinal axis. Methods for operating air vehicles are also provided.

Abstract: A steering system for use in a traveling guided flying apparatus (10) and method for driving the steering system are provided. The system includes an outer housing (111), an inner housing (113) and a support fins (112) extending inwardly from the outer housing (111) and holding the inner housing (113) thereon. The outer housing (111) and the inner housing (113) define a ram air inlet (114) at a nose of the forward portion (11), an annular inlet air passage (115), an annular pressure chamber (116), and an outlet air passage (125). The steering system further includes exhaust outlets (120) arranged in the outer housing and separately controlled valves (124) mounted at the exhaust outlets (120) configured to vary the flow of escaping air through the exhaust outlets (120). The steering system also includes a target seeker (121), one or more pressure sensors (119) mounted in the pressure chamber (116) and a control unit (122) for controlling flight of the guided projectile (10).
