Accreted ice thickness measuring probe for aircraft, has oblong case, heating resistors to melt down accretion of ice around probe, and longitudinal window transversely directed to aerodynamic flow

摘要

The probe has an oblong case, a base (2) implemented on a surface, and measurement stages superimposed orthogonal to the base. Each stage has an emitter to emit a light beam parallel to the base, and a receiver to receive the light beam after reflection on the ice. Electrical heating resistors superficially melt down the accretion of the ice around the probe. A longitudinal window (5) is transversely directed to an aerodynamic flow. An independent claim is also included for a device permitting the determination of the thickness of an ice accretion on a surface and comprising several probes.
