Torque and Axial Loading Physics for Measuring Atmospheric Icing Load and Icing Rate

Abstract

Measuring icing load and icing rate are important parameters for an atmospheric icing sensor. A new icing sensor has recently been designed and developed at Narvik University College for measuring atmospheric icing rate, icing load and icing type. Unlike the existing atmospheric icing sensors commercially available in market, which uses the axial loading for measuring icing load and icing rate, this new sensory system measures icing load and icing rate using the torque loading physics. The performance of this new icing sensor has been tested and validated at cryospheric environment simulator Japan. This research work focus upon the lab based experimentation and evaluation of axial loading and torque loading sensory physics during an icing event. Results show a significant performance difference between torque and axial loading physics for atmospheric icing sensors.
