Air_ray: floating manta ray with beating wing drive

Air_ray

Floating manta ray with beating wing drive

In search of new drive concepts, our Bionic Learning Network came across the manta ray. With the Air_ray, we have now transferred the fascinating motion sequences and the flow-optimized body shape into the world of technology. Thanks to its lightweight construction, the buoyancy of helium and the beating wing drive with Fin Ray Effect®, the remote-controlled flying object moves through the air like its natural role model through the water.

The flow-optimized design of the artificial ray increases aerodynamic efficiency. The active rotation of its beating wings ensures full power development in the air. A servo motor pulls alternately on the two flanks in the longitudinal direction and thus moves the wing up and down in a targeted manner.

With an additional servo drive, the beating wing can be rotated in its transverse axis, which means that the Air_ray can also be maneuvered backwards. The motion sequence comes very close to that of the biological role model.
