A probe head for an air data probe includes a ceramic body and a heater embedded within the ceramic body.

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.

A pitot tube includes an outer tube extending from a first tube end to second tube end. The second tube end defines a tip portion of the pitot tube. A tube sleeve is located inside of the outer tube and defines a tube passage extending from the first tube end to the second tube end. A heating element is located between the outer tube and the tube sleeve. The heating element is isolated from airflow into the tube passage. A method of forming a pitot tube includes installing a heating element to an outer surface of a tube sleeve, the tube sleeve defining a tube passage of the pitot tube. The tube sleeve is secured in an outer tube such that the heating element is between the tube sleeve and the outer tube and is isolated from airflow through the tube passage.

The plurality of core applications includes a coarse data processing application configured to monitor and analyze the sensed data to generate a first data output.

An HVAC system is monitored or tested using a tube with a measurement instrument in the tube. The tube is connected to an HVAC system and an output of the HVAC system is measured using the measurement instrument. The tube is connected between the HVAC system and a volume to be conditioned. A reading of the measurement instrument is noted while the tube is connected between the HVAC system and volume. The volume is disconnected from the tube and a valve is connected to the tube. The valve is adjusted until the reading of the measurement instrument is approximately the same with the valve as when the volume was connected. A setting of the valve is noted and then used to test the HVAC system in the future or to test other HVAC systems simulating the same load.

A multi-function air data probe comprises a probe stem having an outer surface that extends between a first end and an opposite second end, with the probe stem having a first cross-sectional diameter; and a probe head having an outer surface that extends between a proximal end and a distal end, wherein the proximal end of the probe head is coupled to the first end of the probe stem. The probe head has a second cross-sectional diameter that is larger than the first cross-sectional diameter of the probe stem. A plurality of multi-hole ports is located in the probe head, with the multi-hole ports extending into and through the probe stem. The air data probe is operative to make measurements used to determine one or more of angle of attack values, total pressure values, and static pressure values.
