Abstract

An icing detector probe includes three sections arranged sequentially along the direction of air flow, namely, a first section, a second section and a third section. The shape of the outer surface of the first section is suitable for collecting droplets in the air flow. The shape of the outer surface of the second section is suitable for full decelerating and releasing latent heat of large droplets during their movements. The outer surface of the third section is suitable for icing of large droplets. The probe detects icing by distinguishing and identify large droplets icing. The probe effectively detects types of traditional icing, thus being helpful for exact detection of icing thickness. An icing detector including said icing detector probe is also provided.

Claims

a first segment, a second segment and a third segment arranged in ordered sequence in an air flow direction, wherein an outer surface of the first segment is shaped for adapting to collect water droplets in the air flow;

an outer surface of the second segment is shaped to enable large water droplets to sufficiently decelerate and release latent heat during movement thereof;

an outer surface of the third segment is configured to enable large water droplets to get iced thereon.

2. The ice detector probe according to claim 1, wherein the second segment has a certain length measured in the air flow direction.

3. The ice detector probe according to claim 1, wherein the outer surface of the second segment is shaped to enable the large water droplets to be essentially continuously subjected to an action of a boundary layer during movement.

4. The ice detector probe according to claim 1, wherein the second segment comprises a normal-state icing area for normal-state water droplets to get iced thereon.

5. The ice detector probe according to claim 4, wherein the normal-state icing area is substantially configured in a wedge shape as viewed from one side.
