(57) [Abstract] [Purpose] The conventional publicly-known technology is complex and precise, large, and very expensive, and clears the difficult problem that was considered impossible at all for the general public. As a small, lightweight and inexpensive new transportation system, we propose a vehicle for water, land and air 3 that enables all of water navigation, land traveling, and aerial flight (vertical, horizontal, stop). [Structure] The rotor wing surrounded by a cylindrical duct achieves both vertical flight and air suspension at high efficiency and miniaturization compared to a conventional helicopter. By a simple operation of the column device that has the function of stabilizer and control wing that connects the cylindrical duct, the cylindrical duct is transformed into a fixed wing during horizontal flight to increase the flight efficiency, and the lower part of the fuselage or duct It is equipped with small and lightweight wheels and propulsion units, and is designed to be able to freely carry out land and water navigation. |
