Giant floating air-ray swimming through the air - video
Here is a giant floating air-ray, a stingray in the air, that appears to be self moving. Air_ray is a remote-controlled hybrid construction consisting
of a helium-filled balloon and a beating wing drive. Its light design makes it possible for it to “swim” in the sea of air, boosted by helium, in a
similar way to the manta ray in water.
Propulsion is achieved by a beating wing drive. The servo drive-controlled wing, which can move up and down, utilities the Fin Ray Effect® and is based on alternate pulling and pushing flanks connected via frames. When pressure is exerted on one flank, the geometrical structure curves automatically against the direction of the influencing force. A servo drive pulls the two flanks alternately in the longitudinal direction, thus moving the wing up and down.
