Efficient ice protection systems – Timing is everything

**NEW PUBLICATION** Aircraft without ice protection systems will face severe issues when flying in icing conditions. To reduce the risk of losing the aircraft, the aircraft must either remain grounded when the risk of icing exists, or it must be equipped with an ice protection system. As of today, no mature ice protection system existsContinue reading “Efficient ice protection systems – Timing is everything”

Why we need a special icing severity index for unmanned aircraft

**NEW Publication** Icing severity indices are ameasure for the in-flight icing risk and are an important factor for path and mission planning. Small aircraft, such as unmanned aerial vehicles (UAV) and urban air mobility (UAM) vehicles, are particularly sensitive to icing and thus proper assessment of weather risks is critical. Icing severity is a metricContinue reading “Why we need a special icing severity index for unmanned aircraft”

Challenges for icing CFD and unmanned aircraft

**NEW PUBLICATION** Computational fluid dynamics (CFD) simulation methods are one of the most important design and development tools for aircraft – manned or unmanned. For the challenge of in-flight icing, special icing CFD codes have been developed such as FENSAP-ICE or LEWICE3D. These tools can simulate and predict the behavior of airfoils and aircraft in icingContinue reading “Challenges for icing CFD and unmanned aircraft”

1st UAV Icing Workshop announced

The workshop will be hosted by the UAV Icing Lab at the Norwegian University of Science and Technology (NTNU). The objective of this workshop is to provide a platformContinue reading “1st UAV Icing Workshop announced”

Ice shedding detection and how it helps to operate UAVs in icing conditions

Written by Bogdan Løw-Hansen, PhD candidate. Today, harsh weather conditions and especially icing are a big problem for uncrewed aerial vehicles (UAVs). Several solutions exist, but many require substantial amounts of energy to operate them, which are not always available on smaller UAV platforms. To this end, the UAV Icing Lab at NTNU is currentlyContinue reading “Ice shedding detection and how it helps to operate UAVs in icing conditions”

Can ice fragments destroy a UAV propeller?

In one of our recent icing wind tunnel experiments, the NTNU UAV Icing Lab investigated if ice fragments are a hazard to UAV propellers. The resulting high-speed video footage shows the moment ice impacts the propeller blades. Here is a small preview of the footage. When an aircraft flies into special meteorological weather conditions, iceContinue reading “Can ice fragments destroy a UAV propeller?”

Cooperation with the German Aerospace Center (DLR)

The Norwegian University of Science and Technology (NTNU) has signed a collaboration agreement with the German Aerospace Center (DLR). The scope of the agreement is to conduct joint research in the field of icing on unmanned aerial systems (UAVs). The collaboration is going to be pivoting around the NTNU UAV Icing Lab the the DLRContinue reading “Cooperation with the German Aerospace Center (DLR)”

How is an UAV affected by in-flight icing and can we simulate it accurately?

**NEW MASTER THESIS** One of the master students of the UAV Icing Lab has finished his thesis work. Johannes Oswald conducted his thesis in collaboration with the Institute of Aerodynamics and Gas Dynamics at the University of Stuttgart and the von Karman Institude for Fluid Dynamics. Read more about this research project here. Ice build-upContinue reading “How is an UAV affected by in-flight icing and can we simulate it accurately?”

Why is icing on UAVs important?

In-flight icing of drones is a severe hazard that significantly limits the usage of autonomous unmanned aerial vehicles (UAVs). The UAV Icing Lab has the mission to provide knowledge and solutions for the operations of unmanned aircraft in icing conditions. Atmospheric icing is a well known phenomenon in the Nordic countries. Icing on power linesContinue reading “Why is icing on UAVs important?”
