Abstract
An ice protection system (20) comprising an electrothermal device (30) responsible for maintaining an aircraft surface (14) at an anti-ice temperature greater than 0° C. An optimum power input to the electrothermal device (30) is based on outside air temperature sensed by an OAT sensor (30) and on liquid water content detected by an LWC detector (50). The system (20) can be preferably characterized by the absence of surface-temperatures sensors.
Claims17
A method of supplying power to an electrothermal device (20) to maintain a surface (14) at a predetermined anti-ice temperature, the method comprising:
- sensing outside air temperature with an OAT sensor (30);
- detecting liquid water content with an LWC detector (40);
- determining an optimum power input based on an OAT constituent and an LWC constituent;
- and
- supplying power to the electrothermal device (20) at the determined optimum power input.
A method as set forth in the preceding claim, wherein said optimum-power-determining step is characterized by the absence of surface-temperature-measurement inputs.
