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.
In recent years, electrification has been described as having an important role in reducing emissions from future aviation. Due to the challenges posed by longer ranges, interest is chiefly
