Abstract: A sensor for detecting icing conditions in an airstream includes a flow housing (12,80) mounted on an aircraft (10) and in which one or more probes (34,38,60,92) are mounted. At least one of the probes (34,92) is subjected to impingement of the airstream and liquid moisture droplets in such airstream. The heat removal, or cooling effect on the probe (34,92) in the airstream carrying liquid droplets is determined. A temperature signal indicating the airstream temperature is combined with signals from the at least one probe (34,92) for determining whether or not icing conditions are present.

Abstract: Systems and methods for detecting ice particle accumulation are disclosed herein. In one exemplary implementation, a method for detecting ice is described in which a parameter within an interior volume of a heated conduit is measured. The method also includes detecting the presence of an accumulation of ice particles based on the parameter measured within the interior of the heated conduit.

Abstract: A temperature sensor (10) is provided with at least two thermometers or temperature sensing elements (33,34,130,200,204) that have different recovery factors, and which are in the same airflow. The recovery factors for the respective thermometers (32,34,130,200,204) are determined for the sensor and stored in a memory of a processor (40,172). The temperature measured by each of the thermometers (32,34,130,200,204) is provided to the processor (40,172), and the processor (40,172) establishes ratios using the recovery factors and measured temperatures to determine total temperature and static temperature of the airflow in which the thermometers (32,34,130,200,204) are placed.

Abstract: The present invention relates to providing a temperature sensing probe (12,55) that is mountable on an aircraft (10) and includes a thermometer or temperature sensing element (38,57) for sensing temperature of airflow. A heater (35,35B) is provided on the probe to bias the temperature sensed by the thermometer or temperature sensing element (38,57), in a manner such that the temperature measured is at a substantially known offset from the static temperature surrounding the temperature sensing probe (12,55). Control of the offset can be achieved by regulating airflow or heat provided. The heating effect is controlled to be a substantially equal and opposite match to the decreased total temperature resulting from lower airspeed or decreased airflow. In this manner, the thermometer or temperature sensing element (38,57) will essentially operate at a fixed offset above static temperature, that is the temperature in undisturbed air in which the aircraft (10) is operating, over a fairly wide range of flow rates.
