以自然界的鳐鱼为模板的“空中鳐鱼”是一种由远程遥控的氦气气囊和羽翼振动产生驱动力组成的混合体。它轻便的设计借助氦气的浮力让它可以在广阔的空中“遨游”，这种方法与水中的鳐鱼相似。 “空中鳐鱼”的驱动力由羽翼振动产生。利用射线效应并基于与四周有连接的拱侧翼交替推拉运动的原理，私伺服控制的羽翼可以上下移动。当一侧受到压力时，它几何形的结构会自动向受力的反方向卷曲。一个伺服驱动两片侧翼交替地纵向移动，驱使羽翼上下运动。Air_ray, modelled on the manta ray, is a remote-controlled hybrid construction consisting of a helium-filled ballonet and a beating wing drive. Its lightweight design enables it to “swim” in the sea of air using the lift from the 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, utilises the Fin Ray Effect and is based on alternate pulling and pushing flanks connected via frames. When pressure is exerted on one edge, the geometrical structure automatically curves against the direction of the influencing force. A servo drive pulls the two flanks alternately in longitudinal direction, thus moving the wing up and down.
