Silent Drones Propelled by 3D-Printed Sound-Powered Engines

By PulseAugur Editorial · [1 sources] ·

Researchers at EPFL have developed a novel sound-powered engine capable of propelling micro-drones and other small devices. This engine utilizes the resonant frequency of a 3D-printed cavity to generate directional thrust by oscillating air molecules and expelling them through a nozzle. The technology has been demonstrated in a silent hovering microflier that reaches over 12,000 RPM and a small boat, with potential applications for quiet drone propulsion. AI

IMPACT This novel propulsion method could enable entirely new classes of silent, agile micro-drones for various applications.

RANK_REASON The cluster describes a new research finding and prototype development in the field of propulsion systems for micro-drones. [lever_c_demoted from research: ic=1 ai=0.4]

    3D-printed sound-powered jet engines propel micro drones — fliers are completely silent; researchers use ultrasonic frequencies to drive 12,000-RPM silent hovering fliers

    A specially shaped 3D-printed resonator can make air shoot out of its nozzle and provide thrust when it hit with the proper frequency. While the prototypes don't deliver practical levels of thrust yet, they show proof that the concept works.
