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.

Abstract: A thermal management device for a battery pack 104 of an UAV is disclosed. The thermal management device 100 comprises an insulating enclosure 102 that is made of a material comprising at least an EPP foam for enclosing the battery pack 104, and one or more heating coils 110. The heating coils 110 are electrically powered from an external power source 112 for pre-heating the insulating enclosure 102 to a predefined temperature before flight of the UAV. The EPP foam of the insulating enclosure 102 provides high thermal insulation for retaining the heat of the insulating enclosure 102 for heating the battery pack 104 and maintaining the temperature of the battery pack 104 above a threshold temperature when the UAV flies in a sub-zero ambience temperature. The insulating enclosure 102 with the one or more heating coils 110 are configured to provide uniform heat distribution across the battery pack 104.
