Are unmanned aircraft more sensitive to icing compared to manned aircraft?

**NEW Publication** A recent paper investigates the sensitivity of unmanned aircraft to icing in comparison to manned aircraft. Differences in airframe size and airspeed can lead to substantially different icing performance penalties. Think of a “normal” aircraft. Chances are that you are thinking of something that is officially called a “large transport aircraft” – aContinue reading “Are unmanned aircraft more sensitive to icing compared to manned aircraft?”

How often do drones encounter icing conditions?

We often hear the following question: “How often do drones actually encounter icing conditions?”. This is a very good question – and until recently we had only vague answers. Usually, we would refer to two reports in the literature that discuss icing frequencies for the US and the rest of the world. These two reportsContinue reading “How often do drones encounter icing conditions?”

How much energy is required to prevent ice on UAVs?

**NEW PUBLICATION** In-flight icing on UAVs is a severe hazard that prevents drone operations in bad weather conditions. In order to overcome this limitation, UAVs can be equipped with ice protection systems that mitigate the negative effects of icing. One solution is to heat the exposed surfaces of the aircraft electrically with carbon fiber materials.Continue reading “How much energy is required to prevent ice on UAVs?”
