Abstract
In an icing condition detection system, a circuit provides an output representing impending icing conditions as a function of power consumption of a single element detector. A thermal isolation pedestal includes a detector support end that supports the single element detector and an opposite strut mounting end. A thermal isolation controller controls a thermal isolation pedestal temperature to thermally isolate the single element detector from a strut mounting end.
Claims20
An icing condition probe, comprising:
- a detector that includes a first resistive sensing element that is powered to maintain a regulated detector temperature, the first resistive sensing element providing a probe output that represents detector power consumption as an indication of impending icing conditions in an air flow;
- a strut that has a strut mount adapted to mount to an aircraft skin and that includes a strut heater;
- and
- a thermal isolation pedestal that is mounted on the strut and that supports the detector in the air flow, the thermal isolation pedestal including a second resistive sensing element that is powered to maintain a regulated thermal isolation pedestal temperature that is equal to the regulated detector temperature within a regulated temperature range.
