Three years ago he put together a quadcopter and gets to pull out this kind of UFO, really impressive. Now the Romanian inventor and engineer Razvan Sabie turned its attention to electric eVTOLs, but still managed to impress. Gentlemen, here's a bat that couldn't be crazier. Mad Bat, that is: the future is a tail sitter
More than an aircraft (of which a prototype already exists), Mad Bat is designed as a real system. It can scale from small drones to personal planes, air taxis and more. But let's take a step back: most engineers use wings to keep the plane off the ground in hovering and to switch from vertical to horizontal flight. Techniques that end up "imitating" traditional aircraft.
Mad Bat no. This eVTOL does something truly unique, with a heavily modified tail sitter system. The tail sitter, I say to those unfamiliar with the term, is a docking that changes its attitude during the different phases of flight: its vertical propellers allow it to take off easily, but then move horizontally to ensure a rapid flight.
The tail sitters used up until now were uncomfortable (take this ZEVA, for example): they required the pilot to lie down in the cabin. Mad Bat saves goat and cabbage, allowing the use of a tail sitter but also of a very comfortable cabin, always kept straight with a gyroscope system.
How Mad Bat's tail sitter is done
The Mad Bat features four sets of landing gear on various parts of the wings and under the cabin, making it capable of taking off or landing like a typical airplane. The design, I find this really interesting, is accident-proof: this structure that surmounts the cabin automatically inflates a sort of "paraglider" that allows a safe landing in any situation.
Furthermore, on the ground this tail sitter allows the aircraft to have a very small footprint: it can practically be parked anywhere.
Will we remember this type of invention as the one underlying all eVTOLs of the near future? If it doesn't bring out any weaknesses, this design could truly revolutionize the personal flight industry. Please take note.
