Detection and rate of growth of ice on aerodynamic surfaces using its optical characteristics

Abstract

Purpose

This paper aims to reports the further developments of an optical sensing technique, relying on Mie scattered and reflected light, from the ice surface and volume, to determine the ice accretion rate as well as the ice type.

Design/methodology/approach

By measuring the optical intensity of the backscattered and reflected light, the paper demonstrates that it is possible to obtain information on the onset of icing as well as determine the thickness and type of ice accreted on the leading edge of a wing in real time.

Findings

This work is important in the design and development of optical direct ice detection sensors for aerospace applications.

Practical implications

This work is aimed at showing a new approach to ice detection.

Originality/value

Original concept follow on paper from pervious publication.
