Abstract
A sensor assembly includes a metallic layer positioned at least partially on an insulating material coupled to a fuselage of an aircraft. The sensor assembly further includes a pair of terminals arranged at opposite ends of the metallic layer and a temperature probe thermally coupled to the metallic layer. The metallic layer is heated by a heater thermally coupled to the metallic layer. The temperature probe is used to determine a rate of cooling for the metallic layer, responsive to an air flow over the metallic layer.
Claims21
A sensor assembly, comprising:
- a metallic layer positioned at least partially on an insulating material, the insulating material coupled to a fuselage of an aircraft;
- a pair of terminals arranged at opposite ends of the metallic layer;
- a temperature probe thermally coupled to the metallic layer, the temperature probe positioned on an underside of the metallic layer and arranged within the insulating material;
- and
- a heating circuit that includes, at least in part, the metallic layer, the heating circuit providing electrical energy to adjust a temperature of the metallic layer.

A sensor assembly, comprising:
- a sensing layer positioned along at least a portion of an aircraft fuselage;
- an insulating layer coupled to the portion of the aircraft fuselage, at least a portion of the sensing layer being coupled to the insulating layer to thermally isolate the sensing layer from the aircraft fuselage;
- a first terminal positioned at a first end of the sensing layer, the first terminal arranged within the insulating layer;
- a second terminal positioned at a second end of the sensing layer, opposite the first end, the second terminal arranged within the insulating later;
- a sensor coupled to the sensing layer, the sensor positioned within the insulating later;
- and
- heating circuitry coupled to the sensing layer, the heating circuitry configured to direct a current through the sensing layer, via the first terminal and the second terminal, to increase a temperature of the sensing layer relative to an ambient temperature.
