Abstract: A probe includes a probe head, a probe tip extending from the probe head and having a sensor in fluidic communication with a first fluid stream, a pressure channel extending into the probe tip through the sensor face with a pressure sensor that senses pressure in the pressure channel, and a temperature channel extending into the probe tip through the sensor face. The temperature channel including a temperature orifice disposed on the sensor face and at least one exit port distal from the sensor face. The temperature channel is parallel to and fluidly separate from the pressure channel and includes a temperature sensor that senses temperature in the temperature channel. The temperature channel directs fluid flow from the temperature orifice to the at least one exit port, thereby discharging fluid flow into a second fluid stream.

Abstract: Apparatus and associated methods relate to predicting failure and/or estimating remaining useful life of an air-data-probe heater. Failure is predicted or useful life is estimated based on an electrical metric of the electrical operating power provided to a resistive heating element of the air-data-probe heater. The electrical metric of the air data probe heater is one or more of: i) phase relation between voltage across the resistive heating element and leakage current, which is conducted from the resistive heating element to a conductive sheath surrounding the resistive heating element; ii) a time-domain profile of leakage current through the heating element insulation during a full power cycle; and/or iii) high-frequency components of the electrical current conducted by the resistive heating element and/or the voltage across the resistive heating element.

Abstract: A microelectromechanical system (MEMS) strain gauge pressure sensor includes a top wafer stack having a top surface and a first cavity that is configured to receive a first fluid at a first pressure, a backing wafer having a bottom surface opposite the top surface of the top wafer stack; a diaphragm wafer positioned between the top wafer stack and the backing wafer and having a second cavity that is configured to receive a second fluid at a second pressure, and a pedestal connected laterally to the top wafer stack, the backing wafer, and the diaphragm wafer. The diaphragm wafer includes a diaphragm extending between the first cavity and the second cavity, and a resistor positioned on the diaphragm. The MEMS strain gauge pressure sensor has a central axis such that the MEMS strain gauge pressure sensor has mechanical symmetries about the central axis.

Abstract: An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a first end of the wiper arm, and an output shaft coupled to a second end of the wiper arm. The wiper blade includes a support member coupled to a blade element through a clip and a fastener extending through the blade element. The support member can be made from a composite material and the clip and fastener allow for attachment of the blade element to the support member without piercing the support member.

Abstract: An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a first end of the wiper arm, and an output shaft coupled to a second end of the wiper arm. The wiper blade is configured to clean water, dirt, and other debris from the windshield of the aircraft. The output shaft is configured to rotate and cause the wiper arm with the coupled wiper blade to sweep across and clean the windshield. A sensor and a trigger are coupled to an actuator to ensure accurate sweep angle and parking position of the wiper arm and wiper blade.

Abstract: 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.

Abstract: A system and method for monitoring leakage current in a heater connected to a heater power supply by a power cable having a first power lead conducting an inlet current defining an inlet current direction and a second power lead conducting an outlet current defining an outlet current direction that is opposite the inlet current direction. The system includes a differential current electromagnetic sensor having a magnetic core with a center region that the power cable passes through one or more times. The magnetic core has an air gap in which a magnetic flux sensing device is positioned and configured to provide a signal that is representative of magnetic flux across the air gap, which is indicative of a difference between the inlet current and the outlet current. This difference defines the leakage current.
