Abstract:
1. A system for detecting the presence of ice in a cloud as the system passes through the cloud, the system comprising: a first thin walled semicylinder-shaped sensor, said first sensor having a concave inner surface and oriented longitudinally in a leading edge of an airfoil so that cloud water flows towards and into contact with the concave inner surface; a second thin walled semicylinder-shaped sensor, said second sensor having a convex outer surface and being at least substantially the same size as the first sensor, the second sensor further being oriented longitudinally in the leading edge of the airfoil so that cloud water flows towards and into contact with the convex outer surface; a temperature controlling arrangement for: a comparison arrangement for: whereby the difference evidences at least one of a presence of and a predetermined amount of ice in the cloud water.
