"The electrification of aviation is viewed as a crucial component in the
creation of a fossil fuel-free future. However, electric aviation is faced with
a challenge: the more energy-efficient the aircraft, the louder it becomes.
Fortunately, researchers at Chalmers University of Technology in Sweden have
developed an optimized propeller design that opens up the possibility for
electric aviation to be both quiet and efficient.
Electrification has been touted as a key factor in mitigating emissions from
the aviation industry in recent years. The main area of focus for
electrification is short-distance electric propeller planes, as they present
fewer obstacles in terms of range limitations. Propellers driven by electric
motors are deemed to be the most efficient propulsion system for regional and
domestic flights.
But while airplanes are electric, propellers cause another kind of emission –
noise. The noise from the propeller blades wouldn’t just disturb air
passengers. Future electric aircraft will need to fly at relatively low
altitudes, with noise disturbance reaching residential areas and animal life."
