Abstract
A fixed-wing VTOL hybrid UAV is disclosed comprising: a central frame 104; a pair of quick lockable fixed-wings 102 comprising right wing 102-2 and left wing 102-1 that lock with each other over the central frame; and four electrically operated rotors 108 in downward facing configuration attached to fixed-wings with help of rotor-blade arms 110. Arms 110 are pivotally fixed to wings 102 so that arms 110 are movable between a working position in which arms 110 are oriented parallel to central frame 104, and a storage position in which arms 110 are aligned with wings 102. Central frame 104 is a thin rod and works as fuselage. Drivers and control modules are fitted in wings 102. UAV includes rudders attached to arms at 45 degrees for maneuvering UAV for yaw and a secondary roll response. UAV includes two landing gears 106 attached to each end of central frame.
