An air data probe includes an air data probe body and an additively manufactured heater on the air data probe body.

Additively manufactured heaters for air data probes

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.

Bulkheads for air data probes

A probe head of an air data probe includes an insert, a portion of a heater, an outer shell, a tip weld, and a braze. The insert includes a first end, a second end opposite the first end, and a body portion extending between the first end and the second end. The body portion includes a groove. The portion of the heater is positioned within the groove. The outer shell surrounds the insert and the portion of the heater. The outer shell includes a tip portion defining a first end of the outer shell and a body portion extending from the tip portion defining a second end of the outer shell. The tip weld is between the outer shell and the first end of the insert, and the braze is between the insert and the second end of the outer shell adjacent a second end of the insert. The portion of the heater is hermetically sealed between the insert and the outer shell.

An air data probe includes an air data probe body and an additively manufactured heater on the air data probe body, the heater including a first heater layer and a first dielectric layer on the first heater layer. The first dielectric layer makes up an exterior surface of the heater.

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.

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.

Blockage preventing and heated air data probe

A probe head of an air data probe includes an insert, a portion of a heater, an outer shell, a tip weld, and a braze. The insert includes a tip portion making up a tip of the air data probe, an end portion, and a body portion extending between the tip portion and the end portion. The body portion includes a groove. The portion of the heater is positioned within the groove. The outer shell surrounds the body portion of the insert and the portion of the heater. The tip weld is located between the tip portion of the insert and a first end of the outer shell, and the braze is located between the end portion of the insert and a second end of the outer shell. The portion of the heater is hermetically sealed between the insert and the outer shell.

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.

Air data probe repair

A MEMS device includes a backing wafer with a support portion and central back plate connected to the support portion with spring flexures, a diaphragm wafer with a support portions and a sensing portion connected to the support portion with spring flexures, a passivation layer on the diaphragm, and a topping wafer. The device allows for stress isolation of a diaphragm in a piezoresistive device without a large MEMS die.

Piezoresistive sensor with spring flexures for stress isolation

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.

Air data probe with improved performance at angle of attack operation

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.

Air data probe assembly method

Moisture resistant air data probes

An air data probe includes a probe head defining a longitudinal axis between a forward tip and aft base. The probe includes a thermocouple having a sense end in the forward tip to measure the temperature in the forward tip. The probe includes a port opening defined in a side of the probe head and opening at an angle with respect to the longitudinal axis. The probe includes a bulkhead within the probe head. The bulkhead 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.
