摘要： 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.

摘要： 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.

摘要： 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. Other embodiment have unique shapes.

摘要： 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.

摘要： 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.

摘要： A method of repairing an air data probe includes assessing an air data probe for a damaged portion. The method includes depositing a material on the air data probe to repair the damaged portion of the air data probe. An air data probe includes a probe body including a sense port inlet defined through a wall of the probe body. At least a portion of the wall surrounding the sense port inlet is defined by a deposited material having a different microstructure than a material defining another portion of the wall.
