    Abstract: A pitot tube includes a substantially cylindrical body portion having an interior defining a flow passage, and a tip portion extending along a pitot tube axis from the body portion. The tip portion includes an inlet opening, a radially tapered outer surface extending from the body portion toward the inlet opening, one or more bulkheads disposed at the interior to limit travel of particles ingested into the interior, at least one drain opening disposed directly adjacent to one of the one or more bulkheads, and one or more electrical coils comprising one or more coil wraps disposed at an interior of the pitot tube. The one or more coil wraps establish a variable watt density along the interior of the pitot tube. The one or more coil wraps also establish a variable watt density downstream of one or more of the one or more bulkheads.

    Abstract: In accordance with at least one aspect of this disclosure, an air data probe includes, an outer shell defining an airflow path from an inlet at a proximal end thereof to a distal end thereof and a heater configured to be installed within the outer shell an in the airflow path, the water dam comprising, one or more sensing elements at a distal end thereof. The system also includes, a water dam disposed on or in the heater winding and between a proximal end and distal end of the heater winding configured to impede a flow of water droplets and ice crystals to permit proper drain hole operation, prevent moisture buildup in rear areas of the probe and pressure lines, and prevent interaction of the flow of water and the one or more sensing elements. The water dam is configured to mechanically stabilize itself on or in the heater winding during installation of the heater winding and water dam into the outer shell.

    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 the forward tip. A first conduit is in fluid communication with the port opening to guide fluid flow from the port opening to a first chamber. The first chamber is downstream from the port opening. A second conduit, offset radially and circumferentially from the first conduit, is in fluid communication with the first chamber to guide fluid flow from the first chamber to a second chamber. The second chamber is downstream from the first chamber. The offset between the first and second conduits is configured to prevent particle ingestion from the port opening from entering the second conduit.

    Abstract: An air data probe is disclosed. The air data probe may include a probe body having an interior cavity and coated by a protective shell. A sensing port may be disposed in the air data probe and may extend through the probe body. The sensing port may also be lined by the protective shell. The protective shell may be made of an austenitic nickel-chromium alloy, or stainless steel, or any relatively corrosion resistant material. The probe body may be made of nickel, or a nickel alloy, or any relatively thermally conductive material. The protective shell may be joined to the probe body by additive manufacturing, such as laser cladding. In this manner, an air data probe capable withstanding high temperatures without corrosion and yet also being relatively thermally conductive is disclosed.
