* 잠자리처럼 나르는 무인 비행체 VIDEO:Dragonfly-Inspired Aircraft Performs Controlled Flight
Dragonfly-Inspired Aircraft Performs Controlled Flight
A flying machine resembling the works of Da Vinci hit the skies in Russia last month.
Some of the earliest recorded aircraft designs, including the ones depicted in Leonardo Da Vinci's sketches, were ornithopters — machines that incorporated flapping wings, much like birds and insects, in order to lift into the air.
러시아 엔지니어들이 잠자리를 닮은 무인 비행체를 개발했다.
모비긱 등에 따르면 러시아 엔지니어들이 잠자리처럼 날개를 펄럭이면서 이륙해 비행할 수 있는 무인비행체 ‘세러니티(serenity)’를 개발하고 동영상을 공개했다. 이 무인비행체를 개발한 러시아 엔지니어들에 대한 구체적인 정보는 없다.
이 비행체의 길이는 3m 정도이며, 3쌍의 날개를 갖추고 있다. 비행체의 무게는 기존 비행체보다 많이 나간다고 한다. 아직 사람이 탑승할 정도는 아니다. 리모콘으로 비행체를 조작한다.

Now, hundreds of years later, a team of engineers in Russia returned to those insect-inspired roots with a dragonfly-like ornithopter, called Serenity, a Gizmodo report points out.
With its approximately 3.5-meter-long (10 feet) fuselage, three sets of flapping wings, and a network of batteries, wires, and linkages, Serenity impressively achieves lift and can remain airborne using a flapping flying motion.
As the video attests, the flapping does make for a rough ride, and any potential scaled-up passenger version of Serenity might need some kind of gyroscope mechanism to stabilize the fuselage.
Could we see ornithopter flying taxis?
Could we actually see any practical use cases for such a design in the future? In a separate video, one of Serenity's engineers speaks of a "synergy" with today's drone designs.
An aircraft that relies on the movement of its wings for lift does have the potential to greatly reduce noise pollution when compared to a jet engine or propeller machine — though Serenity's squeaking wings do currently sound somewhat like a car alarm.

As ornithopters technically have the capacity to flap their wings and hover, an advanced ornithopter might also allow for greater maneuverability, similar to that of a UAV or a helicopter.
In fact, one group of researchers actually designed a flapping wing drone to imitate the maneuverability of the world's fastest bird, the swift.
What's more, a UAV flying taxi revolution is just around the corner fueled by innovative designs by the likes of GKN Aerospace and Lilium Aviation.
Of course, one could argue that for passengers, ornithopters provide a much more cumbersome, less efficient design than that of helicopters and UAVs — and they'd probably be right. Still, that likely won't stop the crazy dreamers from trying.
