Wing-Flapping Drones and Biomimetics
The word drone has many meanings, but is clarified by context. People drone on about boring subjects, a drone can be a mindless person, bagpipes and other instruments have single-note drone pipes, and more. Our focus today uses what is arguably the most common defintion today, that of unmanned vehicles controlled remotely or by computers. (This child has embedded videos by drones (often called quadcopters) on this site several times.) Modern drones are impressive, but some researchers want to improve their performance. Swift, Wikimedia Commons / Dr. Raju Kasambe ( CC BY-SA 4.0 ) People may recall grainy silent videos of early attempts at flight, some including vehicles that had flapping motions. These may be considered biomimetics , which is drawing inspiration from creation for human applications. Those were on the right track, but the flapping of wings is far more intricate than people can see with the unaided eye. Researchers developed drones that are not flying with propellers.
