Abstract: A flow angle sensor includes a sensing element, a background component connected to and movable with the sensing element, the background component having a marker, a lens (32) adjacent the disk, an image sensor (34) axially aligned with the lens, a light source (38) positioned to illuminate the disk, and an image processing system (36) connected to the image sensor (34). The image processing system (36) provides an angle of attack output based on a location of the marker sensed by the image sensor.

Abstract: An optical sensor (10) for an aircraft includes two detectors (14, 16), a light source (12), and a controller (100). The detectors (14, 16) are oriented along detector paths and have tilt angles and fields of view. The detectors (14, 16) are configured to detect light reflected from an illumination volume and to generate detector signals that correspond to intensities of detected light. The tilt angles are equal such that each detector (14, 16) is oriented in an opposite direction within a plane containing a light source path and the detector paths. The light source (12) is oriented along the light source path and is configured to illuminate the illumination volume which overlaps with the fields of view within a predetermined distance range. The controller (100) is configured to receive the detector signals, detect whether a cloud is present based upon the detector signals, determine a cloud phase, and calculate a density of the detected cloud.

Abstract: A method of operating an optical icing conditions sensor includes transmitting (402), with a transmitter, a light beam and thereby illuminating an illumination volume. A receiver array receives (404) light over a range of receiving angles. The receiver array is configured to receive light having the wavelength over a receiver array field of view which overlaps with the illumination volume. A controller measures (406) an intensity of light received by the receiver array. The controller determines (410) that a cloud is present if the intensity is greater than a threshold value. The controller calculates (412) scattering profile data of the light received by the receiver array if a cloud is determined to be present, which includes an angle of a scattering intensity peak within the range of receiving angles and a breadth of the scattering intensity peak. The controller (414) estimates a representative droplet size within the cloud using the scattering profile data.
