Leonardo da Vinci's 'helicopter' design could make drones quieter

Early Da Vinci designs could help make modern drones stealthier, scientists say

Modernised version of Da Vinci rotor design could produce less sound intensity per unit lift, researchers say

Leonardo da Vinci's 'helicopter' design could make drones quieter

A simulation of the "aerial screw" designed by Leonardo da Vinci in 1480 suggests it would use less power than modern drone rotors to generate the same lift, and make less noise too

Leonardo da Vinci's "Helicopter" Design May Lead to Quieter Drones

Leonardo da Vinci’s sketch of the aerial screw Gianni Dagli Orti/Shutterstock Leonardo da Vinci’s concept for a flying device might have outperformed today’s drones in terms of functionality and noise reduction. Rajat Mittal, a researcher at Johns Hopkins University in Maryland, along with his team, found that Da Vinci’s “air screws”—which were never actually constructed [...] The post Leonardo da Vinci’s “Helicopter” Design May Lead to Quieter …
