Propeller Advance Paves Way for Quiet, Efficient Electric Aviation

Electrification is seen as having an important role to play in the fossil-free aviation of tomorrow. But electric aviation is battling a dilemma: the more energy-efficient an electric aircraft is, the noisier it gets. Now, researchers at Chalmers University of Technology, Sweden, have developed a propeller design optimisation method that paves the way for quiet, efficient electric aviation. Continue reading

German Researchers Find Security Vulnerabilities in DJI Drones

Researchers from Bochum and Saarbrücken have detected security vulnerabilities, some of them serious, in several drones made by the manufacturer DJI. These enable users, for example, to change a drone’s serial number or override the mechanisms that allow security authorities to track the drones and their pilots. In special attack scenarios, the drones can even be brought down remotely in flight. Continue reading
