Simulation of in-flight icing on UAVs

Using icing simulations on unmanned aerial vehicles to develop ice protection systems. Inflight icing is a severe hazard significantly limiting the usage of autonomous unmanned aerial vehicles (UAVs). Researchers at the Norwegian University of Science and Technology (NTNU) investigate icing on UAVs and develop mitigation technologies together with UBIQ Aerospace. This webinar introduces the issues of in-flight icing on UAVs and discusses the following topics:Icing on UAVsDifferences to icing on manned aircraftSimulation of icing and icing penaltiesMeshing of iced airfoils Richard Hann Richard Hann is a researcher at the Norwegian University of Science and Technology (NTNU) on the topic of icing…

How to Mesh a Frozen Drone

Richard Hann, Norwegian University of Science and Technology (NTNU)Icing of drones is a severe hazard that significantly limits the usage of autonomous unmanned aerial vehicles (UAVs). Computational fluid dynamic (CFD) methods, originally developed for manned aircraft icing, are an important tool for understanding the effects of icing on UAVs. One of the most challenging tasks for the simulation is the generation of high-quality meshes of complex ice shapes. Atmospheric icing, also called in-cloud icing, occurs when an aircraft encounters supercooled droplets in the atmosphere. Liquid droplets, with a temperature below freezing, turn into ice when they collide with the airframe.…
