Abstract:
A method of determining an amount of imperfection in an additively manufactured material is disclosed herein. The method includes forming a sample piece constructed from the material during a same additive manufacturing cycle as a design piece constructed from the material, introducing a first electrical current to the sample piece while maintaining the sample piece at a reference temperature, and determining the amount of imperfection in the material depending on the measured resistance and the reference temperature of the sample piece.
Abstract:
An air data probe (10;26;42) includes an air data probe body (12;28;44) and an additively manufactured heater (100-900) on the air data probe body.

Abstract:
A vented module includes a housing portion having a drainage side (30) and a drainage port (32) within the drainage side (30). The module further includes a flame arrestor (10; 110) including a first surface (12; 112) having a fluid inlet (18; 118), a second surface (14; 114) having at least one fluid outlet (24; 124), a labyrinth channel extending from the fluid inlet (18; 118) to the fluid outlet (24; 124), and at least one mesh screen (22; 122) disposed within the labyrinth channel. The flame arrestor (10; 110) is attached to the housing portion such that the drainage port (32) is aligned with the fluid inlet (18; 118).
Abstract:
A temperature sensor includes a sensor body (102) and a wedge extension (104). The sensor body extends from a sensor base (106) to an opposed sensor tip (108) along a longitudinal axis (A). The sensor body has a leading edge (110) and opposed trailing edge (112). The sensor body also has an interior flow passage (114) with an inlet (116) for fluid communication of fluid into the interior flow passage and an outlet (118) for exhausting fluid out from the interior flow passage. The wedge extension is on the sensor body between the sensor tip and the sensor base on the leading edge of the sensor body.
Abstract:
A device (24; 124) configured to prevent ice accumulation includes at least one wall (40, 42) defining a leading edge (44) and a pneumatic passage (46) configured to receive pressurized fluid. The device also includes at least one ejection port (48) formed in at least one of the leading edge (44) and the at least one wall (40, 42), the at least one ejection port (48) fluidly coupled to the pneumatic passage (46) to receive the pressurized fluid therefrom, the at least one ejection port (48) configured to form fluid jets to divert liquid water droplets away from the leading edge (44) of the device.
