When fragments of ice break off the surface, they can pose a hazard to the propeller.  Such ice fragments can be created after long icing periods or in combination with de-icing systems. When an ice fragment hits the blades, there is a risk that the propeller might be damaged or destroyed &#8211; which may lead to the entire aircraft crashing. Especially for UAV propellers, which are often small and lightweight, this is a very relevant risk that can severely affect the safety of the drone. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The NTNU UAV Icing Lab is currently working together with <a href=\"https:\/\/ubiqaerospace.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">UBIQ Aerospace<\/a> and <a href=\"http:\/\/www.mejzlik.eu\" target=\"_blank\" rel=\"noreferrer noopener\">Mejzlik Propellers<\/a> to study this topic.
