A team at Johns Hopkins University has created an unmanned aerial-aquatic vehicle (UAAV) for amphibious drone operations.
An an idea to create a fixed-wing, unmanned vehicle that could autonomously operate underwater and then propel itself into the air as an autonomous flying aerial vehicle is making good success at the John Hopkins University.
Their concept vehicle, dubbed Flying Fish has become a working prototype. See a video on this below:
The prop spins quickly while the UAAV is airborne, but then slows down to a more appropriate speed when it dives below the water’s surface. It speeds up again as the vehicle is about to return to the air, providing sufficient thrust to launch it up and out of the water.
One possible application for the flying fish is for the UAAV to fly itself to a land-locked body of water and then go underwater to collect data. The UAAV can fly in at about 30 miles an hour, dive into the water, collect information and perform reconnaissance, then launch out of the water and return the data.
