The noise that drones give out.

I want to design drones that can fly silently to avoid noise pollution.

Owls are renowned for flying silently and approaching their preys without the preys' knowing. Their feathers have the feature of soft fringes on the trailing edge, which prevents the air flows over the wing from making whistling sounds. The frequency of the air vortex is actually over the hearing capacity of most of their preys, or even human beings. Therefore, we'd like to utilize the feature of an owl's feather to create a drone that can fly silently.

We intend to design a propeller with a special structure that can decrease signals in the frequency range which humans are most sensitive to, thus generating "silent" vortexes.

暗甲蟲。 納米布沙漠之鷹(?

表面有蠟質且有凹凸的帳篷。 每當風接觸到表面時，該結構就會吸收一些蒸氣。 蒸汽慢慢凝結成水。 因此，人們能夠在綠洲中收集水。

甲蟲有許多小突起，稱為吸水端，可以吸收水分，周圍有一層防水的蠟表面。
