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.

Abstract: An air data probe includes a housing and a probe head with a body, total pressure and alpha chambers, total pressure and alpha ports, and alpha drain ports. The total pressure chamber extends through a radial center of the body. The alpha chambers are disposed radially outward from the total pressure chamber. The total pressure port is disposed in a distal end of the body is collinear with a centerline axis of the body. The total pressure chamber is in fluid communication with the total pressure port and with the housing. The alpha ports are disposed downstream of the total pressure port and upstream of the housing. The alpha chambers are in fluid communication with the alpha ports. The alpha drain ports are disposed downstream from the alpha port and upstream from the housing. The alpha drain ports fluidly communicate with the alpha chamber.

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.

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: 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.
