Abstract: A strut for an air data probe includes a socket including a side wall and an end wall. The strut includes a first opening in the socket extending through the end wall of the socket and a second opening in the socket extending through the end wall of the socket and spaced from the first opening. The strut further includes a first pressure path formed within the strut and extending within the strut from the first opening in the socket to a second end of the strut and a second pressure path formed within the strut and extending within the strut from the second opening in the socket to the second end of the strut and spaced from the first pressure path. The strut is monolithic such that the socket, the first opening, the second opening, the first pressure path, and the second pressure path are integral to the strut.

Abstract: A deicing system may include a piezoelectric actuator coupled to an air data probe and configured to vibrate a surface of the air data probe, wherein a vibration of the surface of the air data probe causes a removal of ice from the surface of the air data probe. A deicing system may include a piezoelectric controller configured to control the vibration of the surface of the air data probe by the piezoelectric actuator.

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: A corrosion resistant apparatus for an air data probe with a sleeve being cylindrical in shape with a first end and a second end, at least one circumferentially extending groove on an outside of the sleeve configured to accommodate coils of a heater, and a bore at a center of the sleeve and extending between the first end and the second end configured to provide a pneumatic pathway that allows atmospheric conditions to reach measurement equipment of the air data probe.

Abstract: An air data probe includes a probe head defining a longitudinal axis between a forward tip and aft base. A port opening is defined in a side of the probe head and opening at an angle with respect to the longitudinal axis. A bulkhead within the probe head has a chamber in fluid communication with the port opening. The chamber includes a single chamber inlet having an elongated cross-sectional shape. The single elongated chamber inlet is in fluid communication with two downstream pressure conduits to provide redundancy in case one of the two pressure conduits is blocked.

Abstract: An air data probe has a pitot tube with a tap at a forward end that defines an inner flow path. The inner flow path decreases in the cross-sectional area until reaching a throat. The inner flow path has cross-sections that are generally cylindrical and also has sections of removed material.

Abstract: An air data probe includes a strut including a socket defining an interior surface of the strut and an interior groove extending radially into the interior surface. The air data probe also includes a probe head partially positioned within the socket, the probe head including an exterior surface and an exterior groove extending radially into the exterior surface, the exterior groove being axially alignable with the interior groove. The air data probe further includes a retaining ring partially positionable within the exterior groove and partially positionable within the interior groove when the exterior groove and the interior groove are axially aligned to axially retain the probe head to the strut while allowing the probe head to rotate relative to the strut.
