Abstract: An air data probe includes a probe body including a probe wall. The probe body is formed from a first material by direct energy metal deposition. An insert is positioned in the probe wall. The insert is formed from a second material different from the first material. The insert is encapsulated in the probe wall via the direct energy metal deposition. A method of forming an air data probe includes forming one or more thermally conductive inserts, and encapsulating the one or more inserts into a wall of an air data probe via direct energy metal deposition. The air data probe is formed from a first material and the one or more inserts are formed from a second material different from the first material.

Abstract: An air date probe includes a base portion, a strut portion extending from the base portion, and a tube assembly secured to an extending from the strut portion. One or more of the tube assembly or the strut portion includes a sleeve member having a sleeve outer surface positioned at a sleeve frustum angle relative to a sleeve member axis. A thin film heater is positioned at the sleeve outer surface, and the tin film heater and the sleeve member are positioned in a housing member. The housing member has a housing inner surface having a housing frustum angle such that the thin film heater is retained by compression between the housing member inner surface and the sleeve member outer surface.

Abstract: An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a distal end of the wiper arm, and a drive shaft coupled to a proximal end of the wiper arm. The wiper blade is configured to clean water, dirt, and other debris from the windshield of the aircraft. The drive shaft is configured to rotate and cause the wiper arm with the coupled wiper blade to sweep across the windshield. The wiper arm includes both composite and metal components to reduce the weight of the windshield wiper system while also providing lightning strike protection.

Abstract: A pitot tube includes a wall that extends longitudinally along an axis. The wall defines an inlet aperture at a longitudinal end of the wall, an outlet aperture opposite the inlet aperture, an interior cavity extending from the inlet aperture to an outlet aperture, a passage extending through and perpendicular to the wall having an outlet along an exterior surface of the wall, and an augmenting feature configured to reduce a static pressure at the outlet of the passage. In another embodiment, a wall defines a passage and an augmenting feature that modifies a flow direction of fluid flowing across an outlet of the passage such that a static pressure of the fluid at the outlet is reduced relative to the wall without the augmenting feature.
