    摘要： A flying apparatus includes a main structure and a rotative wing surface, the rotation of the wing surface allowing stabilizing the apparatus (100). A fuselage hangs from the wing surface around a hanging point, allowing the wing surface and the fuselage be moveable independently with respect to each other and the wing surface is configured as a disc to manoeuvre the apparatus and including one or more elements acting as security and secondary command and control surfaces, orienting the apparatus in desired directions. The main structure and wing surface can overwrap at least partially the the fuselage in order to improve the aerodynamic performance.
    The airframe or fuselage and the wing surface are rotatable around any of three rotational axes independently.

    摘要： A clutch has an inner race, an outer race spaced from the inner race and forming a radial cavity between the races, and a plurality of sprags disposed in the radial cavity. The sprags have a different coefficient of thermal expansion (CTE) from the inner race, the outer race, or both races, and a sprag cage retains the sprags at a uniform spacing within the radial cavity. When the clutch is at a first temperature, a gap exists between the sprags and the inner race, between the sprags and the outer race, or between the sprags and both races, and the clutch is disengaged. When the clutch is at a second temperature the sprags are in contact with both the races, and the clutch is engaged.

    摘要： A mechanical system for transmitting rotary motion between firstly at least one inlet wheel driven in rotation by at least one engine, each inlet wheel being suitable for being driven in rotation by a corresponding dedicated engine, and secondly at least two distinct driven shafts of an accessory box, the at least one engine serving to drive rotation of one of the at least two driven shafts in isolation, or to drive the at least two driven shafts simultaneously, jointly with at least one aircraft rotor, the mechanical system including a selective rotary drive member that is movable axially between two distinct drive positions.

    摘要： A contactor with a rotary actuation system, the contactor including a plurality of switching devices configured to switch a plurality of electrical circuits, a plurality of cam followers each operably coupled to one of the switching devices, wherein each cam follower is configured to actuate a switching device, and a cam mechanism, the cam pivotally attached to a point rotation, the cam having plurality of lobes about its perimeter, the cam in operable communication with each cam follower such that upon rotation of the cam mechanism, each cam follower engages a lobe of the plurality of lobes, it causes each cam follower to actuate the respective switching device. The contactor also includes an actuator connected to the cam, the actuator responsive to a control current and operable to rotate the cam and a controller, the controller operable to supply a control current the actuator.
