Abstract

The invention provides an ice crystal detector, which comprises an axially extending ice crystal collecting probe and a detecting device. The ice crystal collecting probe comprises a windward surfaceon one side and a leeward surface opposite to the windward surface, and comprises a rod body, a groove and photoelectric sensors, wherein the groove is positioned on the windward surface and extend inthe axial direction of the rod body, and the photoelectric sensors are arranged at two ends or one end of the rod body. The groove includes an opening and a bottom. The photoelectric sensors form anoptical path in the groove which is spaced from the bottom of the groove for monitoring ice crystals on the bottom of the groove. A controller is connected with the photoelectric sensors and judges whether an ice crystal icing condition exists or not according to the change of the electric signal fed back by the photoelectric sensors. The rod body also comprises a plurality of airflow channels, the inlet of the airflow channels is positioned at the bottom of the groove of the ice crystal collecting probe, and the outlet of the airflow channels is positioned on the leeward surface of the ice crystal collecting probe. The ice crystal detector is simple in structure, high in reliability, easy to achieve and low in electric power consumption, and can be used for detecting whether ice crystal icing conditions exist in the air.

Description

technical field [0001] The invention relates to the field of ice crystal detectors, in particular to an ice crystal detector for detecting whether there is an ice crystal icing condition in the air and a method for the detection. The invention also relates to a mixed-state icing detector for detecting whether ice crystal icing conditions and supercooled water droplets icing conditions exist in the air. Background technique [0002] The icing conditions encountered by aircraft flying in the air include airworthiness provisions 14 CFR Part 25 Appendix C general supercooled water droplet icing conditions (droplet diameter ≤ 50um), 14 CFR Part 25 Appendix O large supercooled water droplet icing conditions (50µm <Water droplet diameter <500µm, called freezing drizzle; water droplet diameter ≥500µm, called freezing rain), and 14 CFR Part 33 Appendix D ice crystal icing conditions. In the present invention, the conventional supercooled water droplets in Appendix C and the la...
