Abstract: A heat shield assembly comprising a sheet of flexible heat shield material and one or more hook and loop fasteners comprising a first part attached to the sheet of flexible heat shield material and a second part configured to be attached to a structure to which, in use, the sheet of flexible heat shield material is to be attached, one of the first and second parts having a plurality of hooks and the other of the first and second part having a plurality of loops such that when the sheet of flexible heat shield material is brought into engagement with the structure, the hooks and loops mesh to secure the sheet of heat shield material to the structure.

Abstract: A heat shield assembly comprising a plurality of heat shield components each comprising a substantially C-shaped structure of heat shield material defining a substantially rectangular body having a top and two opposing elongate side walls extending from respective opposite sides of the top to a bottom edge, the top and the side walls defining a substantially rectangular inner cavity to receive, in use, a rotor lug on the periphery of a rotor disk of a brake stack, each heat shield component further comprising flanges extending outwards from the bottom of the side walls at both sides and both ends of the heat shield component, and wherein the flanges are configured to allow overlap with a flange of an adjacent heat shield component, in use.

Abstract: A shuttle valve is disclosed. The shuttle valve comprises a valve body, a valve member, and a catch. The valve body comprises a first and a second fluid inlet, a central chamber, and a fluid outlet. The first and second fluid inlets and the fluid outlet open into the central chamber via a first and a second inlet mouth and an outlet mouth. The valve member is configured to move between a first and a second position, the valve member closes the first inlet mouth and allows fluid communication between the second inlet mouth and the outlet mouth when the valve member is in the first position, and the valve member closes the second inlet mouth and allows fluid communication between the first inlet mouth and the outlet mouth when the valve member is in the second position.

Abstract: A brake actuator for an aircraft braking system includes a housing having an internal bore, a sleeve mounted for axial movement within the bore of the housing that has a plurality of ratchet teeth on an external surface thereof, a latching mechanism comprising at least one latch mounted for radial movement for engagement with the ratchet teeth of the sleeve. The latching mechanism further includes a latch spring mounted externally of the internal bore for biasing the at least one latch radially inwardly to engage with the ratchet teeth of the sleeve, and a hydraulic brake piston slidably mounted within the internal bore of the housing and extending axially through the sleeve, the piston having a piston head at a first end thereof, and a second opposite end for operative engagement with a brake element, the piston being mounted so as to be movable axially relative to the sleeve.
