Abstract: An approach to seeker windows for aircraft comprises a window layer comprising an IR transparent material, the window layer comprising a first side and a second side substantially opposite the first side; and a heating layer on the first side or the second side of the window layer, the heating layer configured to apply a heating profile to the window layer to reduce thermal shock imparted to the window layer when the seeker window is exposed to hypersonic flight conditions.

Abstract: A rotor body (22) having a plurality of cylindrical bores (24) each adapted to receive a piston (30) for reciprocating movement therein, each of the bores (30) being lined with a ceramic liner (42) having a first split (44), and a method of forming a rotor (16) having a ceramic bore liner (42) that includes the steps of providing a rotor body having at least one bore (140), providing a ceramic bore liner having a first end, a second end and a split having a width (142), and compressing the bore liner to decrease the width and securing the bore liner in the at least one bore (144).

Abstract: An anodization method includes steps of providing an object formed of an aluminum-copper alloy, providing an anodizing bath comprising a basic silicate solution, providing an AC power supply including a first electrode and a second electrode, placing the first electrode in contact with the anodizing bath, connecting the second electrode to the object, placing the object in the anodizing bath, applying a voltage to the first and second electrodes to maintain a current density of about 10 mA/cm2 or less to form an anodized coating on the object, removing the object from the bath, and sealing the anodized coating on the object.

Abstract: A method of manufacturing a wear resistant shoe (26) includes upsetting (46) one end portion (38) of cylindrical member to work harden that portion to a substantial depth, machining (48) the cylindrical member portion to finished dimensions and surface hardening (56) a face (28 or 34) of the machined cylindrical member portion. The cylindrical member may comprise rod stock of a diameter less than the greatest diameter of the finished shoe and be upset or swaged to axially reduce and radially increase the dimensions of the one end portion. A hollow region (30) is formed in an opposite rod stock end portion and the periphery (50) of the hollow region is crimped about a rounded end (18) of the piston (20). The cold work done during the swaging or forming process provides a foundation for hardened faces comprising balance (28) and auxiliary balance (34) lands, forms a crude shape of the shoe, and imparts work hardening and wear property improvements.

Abstract: A connection for establishing a joint between materials having different coefficient of thermal expansion. The connection has a first and second members made from materials that have different coefficient of thermal expansion. The first member has a cylindrical end with a bore therein and a rib located on the peripheral surface of the cylindrical end. The second member has a first diameter section located in the bore of said first member and a second diameter section. A sleeve which surrounds a portion of the cylindrical end of the first member and the second diameter section of the second member has a groove for receiving the rib on the first member. Bolts extend through the sleeve into the second diameter section to establish an external compressive force between the sleeve and the rib to hold the first member and the second member in a fixed relationship and form a unitary structure.
