3D打印声动力发动机驱动的静音无人机

作者 PulseAugur 编辑部 · [1 个来源] ·

EPFL的研究人员开发了一种新颖的声动力发动机，能够为微型无人机和其他小型设备提供动力。该发动机利用3D打印腔体的共振频率，通过振荡空气分子并将其通过喷嘴排出，产生定向推力。该技术已在一种达到12,000 RPM以上的静音悬停微型飞行器和一艘小型船上得到演示，并可能应用于无人机静音推进。 AI

影响 这种新颖的推进方法可以为各种应用带来全新的静音、敏捷的微型无人机。

    3D打印声动力喷气发动机为微型无人机提供动力——飞行器完全静音；研究人员使用超声波频率驱动12,000转/分的静音悬停飞行器

    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.
