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.

Abstract: The present disclosure pertains to a multi-rotor unmanned aerial vehicle (UAV). Aspects of the present disclosure provide a UAV that includes at least four arms, each configured with a co-axial pair of contra rotating propellers, wherein each propeller has capability of rotating reversibly with associated reversal of direction of thrust, and an autopilot control system that controls rotational direction and speed of the at least four co-axial pairs of propellers to maintain yaw stability, roll stability and pitch stability of the UAV, wherein in an event of failure of any one co-axial pair out of the at least four co-axial pairs of propellers, the autopilot control system reverses direction of rotation and thereby direction of thrust of at least one propeller of any functional pair.

Abstract: An improved propeller system is disclosed, including at least one resilient component configured with a mounting arrangement of a propeller of the propeller system. The resilient component is made of a resilient material that allows the propeller to tilt about a tethering axis under conditions of differential lift force on blades of the propeller under an advancing condition and a retreating condition. The resilient component includes a pair of cutouts for locating inserts made of a rigid material and positioned with a longitudinal axis of the inserts oriented in radial direction. The orientation of the inserts results in a radially oriented line contact between the propeller and the inserts to ensure that tilting of the propeller is about longitudinal axis of the inserts, defining the tethering axis of the propeller system.

Abstract: A method for capturing videos and/or images of a target area using a single camera configured with an aerial vehicle (AV) is disclosed including the steps of moving the AV over the area of interest along a straight path; capturing a first set of images of an area down below by pointing an optical axis of the camera towards a first side of the straight path such that the optical axis makes a first set of predefined angles with vertical; and capturing a second set of images of the area down below by pointing the optical axis of the camera towards a second side of the straight path such that the optical axis makes a second set of predefined angles with respect to the vertical. Side overlap between the first and second set of images is optimized to account for error in camera movement.

Abstract: A system and a method for estimating coverage area and viewing area for an Unmanned Aerial Vehicle 104 (UAV 104) is disclosed. It involves creating an operational map of a home location's area coverage 302 pertaining to a complex terrain based on no fly zone polygon data and elevation data, based on the information of the area coverage provided by a navigation unit. The map is created using multiple sample points and validating said sample points by checking whether or not they are at no fly zone or exceeding maximum AGL. Moreover, the operational map is drawn by using home location as a center point. Further, it involves determining and generating coverage area and viewing area of the UAV based on the operational map. It also discloses a feature of checking take-off suitability.

Abstract: A device for self-balancing a rotating part, such as a propeller, along a given axis is disclosed. The propeller 102 coupled to, a drive shaft with freedom for linear movement along longitudinal axis L-L; at least one pair of levers 614/616, comprising a first lever 614-1/616-1 and a second lever 614-2/616-2, that are pivotally mounted on mounting plate 606 at two diametrically opposite points 618; and at least one pair of weights 622 fixed at external ends of the levers 614/616. inner ends of levers 614/616 are operatively coupled to the propeller 102 such that when propeller 102 undergoes a linear movement in any direction along the longitudinal, axis L-L due to unbalance, inner ends of levers are, moved to cause the weights 622 to move to provide a balancing force to neutralize the unbalance in the propeller. An embodiment with only one pair of levers is also disclosed.

Abstract: A multi-rotor Aerial Vehicle with least rotors/propellers and having single arm failure redundancy is disclosed. The AV comprises at least five arms with at least one arm having a co-axial pair of contra rotating rotors/propellers. To maintain yaw stability under normal conditions, half of rotors/propellers are rotated in one direction and other half in opposite direction. In the event of failure of any one of the rotors/propellers located adjacent to the pair of contra rotating rotors/propellers, the one propeller/rotor out of the contra rotating rotor/propeller that is rotating opposite to the failed rotor/propeller is shut off. In the event of failure of a rotor/propeller belonging to contra rotating rotors/propellers, other rotor/propeller of the pair is shut off. In the event of failure of any one of rotors/propellers not adjacent to contra rotating rotors/propellers, the RPMs of other rotors/propellers is adjusted to maintain stability and navigate the Aerial Vehicle.
