Embodiment Construction

[0025] The illustrative embodiments recognize and take into account many different considerations. For example, the various illustrative embodiments recognize and take into account that currently used systems for detecting icing conditions on aircraft cannot detect all the different types of icing conditions that may occur. For example, the various illustrative embodiments recognize and take into account that as the size of water droplets increases, currently used sensors may not detect icing caused by those water droplets. The various illustrative embodiments recognize and take into account that the location at which droplets of different sizes will collide with the airfoil during operation of the aircraft depends on the size change of the droplets.

[0026] The illustrative embodiments recognize and take into account that it is desirable to detect different types of icing conditions that may be caused by different sized water droplets. In particular, the illustrative embodi...

Abstract

The invention provides a supercooled large drop icing condition detection system. The method and apparatus for an ice detection system (806). The ice detection system (806) comprises a first sensor (400) located on a leading edge (412) of a vertical stabilizer (120) on an aircraft (100), a second sensor (402) located on a first side (414) of the vertical stabilizer (120), and a third sensor (404) located on a second side (416) of the vertical stabilizer (120). The first sensor (400) is configured to detect a first type of icing condition (860) for the aircraft (100). The second sensor (402) is configured to detect a second type of icing condition (860) for the aircraft (100). The third sensor (404) is configured to detect the second type of icing condition (860) for the aircraft (100).

Description

technical field [0001] The present disclosure relates generally to detecting icing conditions, and in particular to aircraft icing conditions. More specifically, the present disclosure relates to detecting supercooled water droplets, including supercooled large drops (SLDs). Background technique [0002] Icing on an aircraft may occur during flight when atmospheric conditions cause ice to form on surfaces of the aircraft. In addition, such ice can also occur inside the engine. Ice that forms on aircraft surfaces, at engine inlets, and other locations is undesirable and potentially unsafe for operating the aircraft. [0003] Icing conditions can occur when droplets of supercooled liquid water are present. In these illustrative examples, water is considered subcooled when it is cooled below the stated freezing point of water but is still in liquid form. Icing conditions can be characterized by the size of the droplets, liquid water content, air temperature, and other param...
