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
Researchers at Chalmers University of Technology, Sweden, have developed a propeller design optimization method that paves the way for quiet and efficient electric aviation.
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.

The ambition of developing electric aircraft that are both quiet and energy-efficient is somewhat thwarted by a trade-off problem.
“Modern aircraft propellers usually have two to four blades, but we’ve found that by using six blades designed using our optimization framework, you can develop a propeller that’s both relatively efficient and quiet. The propeller achieves a noise reduction of up to 5-8 dBA with only a 3.5 percent thrust penalty, compared to a propeller with three blades.
