摘要： A de-icing apparatus configured to remove ice from a surface part of an aircraft, the de-icing apparatus comprising a heating layer and a conductive surface extending over, and in heat conductive contact with, the heating layer. The conductive surface defines at least a part of the surface part of the aircraft or an aircraft component. The heating layer comprising heating elements defining substantially closed contour zones, each comprising a periphery formed by the heating elements within which an area is defined; the heating layer and the conductive surface configured such that when power is provided to the apparatus the heating elements which fragment ice formed on the surface part of the aircraft according to the shape of the peripheries of the substantially closed contour zones.

摘要： The system of the present disclosure provides two or more sensors located on two parallel transmission or kinematic paths having different ratios with respect to the actuator position. Each sensor provides a different position measurement output and the difference between the sensor outputs provides a reduced indication of the position of the actuator/moved component. Integrating sensors in the reduction path avoids the need for the reduction gear mechanism.

摘要： A multi-layer braided article and a method of making the multi-layer braided article. The multi-layer braided article includes a braid extending along a first axis, wherein the braid is folded over itself to form a first layer and a second layer; and a wrapper laid over the first layer of the braid and extending circumferentially around the first axis, wherein the wrapper defines an edge of the first layer about which the braid is folded. The multi-layer braided article may form part of a blade for an aircraft. A sleeve may be provided around a conical portion of the article to connect the article to something else, such as a propeller hub, where the multi-layer braided article is formed as part of a blade. The sleeve may provide a primary or secondary load path.

摘要： An aircraft inceptor system includes an inceptor member arranged to be operated by a user to cause a corresponding movement of a moveable aircraft surface. The system also includes means for detecting the operation of the inceptor member by the user and for providing a movement signal, associated with the detected operation, to a flight control computer, the flight control computer providing a control signal to an actuator to move the aircraft surface according to the movement signal. The means for detecting the operation of the inceptor member by the user comprises a force sensor configured to sense the force applied by the user to the inceptor member, the movement signal being derived based on the sensed force.

摘要： A rotating assembly such as a counter-rotating propeller system or a turbofan includes a first rotating part rotatable relative to a second part, the first and second parts mounted on a common axis, a combustion engine arranged to rotate the first part, and an electric motor connected to drive the second part. In a first drive mode, the combustion engine rotates the first part in first direction relative to the axis while the electric motor drives the second part in a second, opposite direction relative to the axis and in a second drive mode, the combustion engine rotates the first part in the first direction and the electric motor does not drive the second part in the second, opposite direction.

摘要： A tank that may be used in combination with an actuating means such as a pneumatic door actuator includes a first, inner, enclosure positioned and enclosed within a second, outer, enclosure, to provide an enclosed chamber between the inner enclosure and outer enclosure. The pressure in the chamber may be measured with a gauge that does not extend into the inner enclosure. The measured pressure may then be monitored and compared in order to detect a change in pressure and thereby also detect a leak through a wall from the inner enclosure. The tank may also be used to inflate and/or deploy an emergency evacuation slide in an aircraft.
