Scientists from Imperial College of London created a reusable drone for underwater research. The device is able to dive under water, carry out the selection of soil and water samples, come out on the surface and, of course, move through the air. Scientists were inspired by flying fish when creating a drone-diver.
The machine`s flying capabilities are supported by a compact jet engine. At a speed of 10 meters per second, the AquaMAV drone can fly for more than 14 minutes after surfacing. The charge of the device is enough for 5 kilometers. The weight of the drone is only 200 grams.
AquaMAV was developed by candidate of technical sciences Mirko Kovac, the leader of laboratory of air robotics at Imperial College, with the participation of Robert Siddall and Alejandro Ortega, leading researchers.
When immersed in the water, drone folds the wings, located on the hull. AquaMAV has a water repellent coating. The body of the drone is made of kevlar and CFRP (carbon fiber) alloy, which provides protection against numerous impacts on the water surface. Developing the design, scientists based on the findings, made during a series of observations of various diving insects and fish.
