US Patent 10919610 Unmanned ellipsoid multi-rotor airship and respective method of construction

An unmanned and remotely controlled airship has a multirotor system combined with an inflatable envelope. The airship may be lifted/powered by a power system that has three or more rotors. The airship may be constructed using rods, connectors, the main system/control box and the rotors. The airship system may have a systemic symmetry for weight distribution and flight control and may be, for example, a symmetric ellipsoid envelope/blimp.
