Due to the escalating extreme weather conditions, the aircraft icing events are increasingly growing. The analysis of this phenomenon has gained increased attention, particularly in the field of aviation safety. A significant contributor to icing is the occurrence of Supercooled Large Droplets (SLD), water droplets suspended in air at temperatures below freezing one. Previous experiments in the scientific community have predominantly focused on the normal impact of these droplets on solid surfaces with low velocities.

Our research aims to expand this understanding by considering rotating surfaces and high relative impact velocities. This approach will closely simulate real-world conditions that an aircraft wing's experience.

The project consists of using an existing single-water-drop impact set-up with a rotating disk and measuring, by means of a chromatic line sensor (CLS), the thickness of the ice layer formed on the disk.
