Various exemplary embodiments relate to a drone. The drone may include: a navigation unit configured to determine the location of the drone and navigate the drone to designated locations; a radio frequency identification (RFID) reader configured to read RFID tag information from RFID tags; and a wireless network transceiver configured to periodically transmit the location of the drone and RFID tag information to an inventory management system. Various exemplary embodiments relate to a method performed by a drone. The method may include: receiving navigation path information; navigating the drone along the navigation path based on satellite location signals; determining current position information based on the satellite location signals; reading RFID tag information from a first RFID tag; and transmitting the RFID tag information and the current position information via a wireless client to a central computing system.

A cooling system includes a rotor (VTOL rotor, cruise rotor) for generating at least one of lift or thrust of an aircraft, a component group formed of a plurality of electrical components for rotating the rotor, and a cooling circuit for cooling the component group, wherein a plurality of the component groups corresponding to a plurality of the rotors are provided, and the plurality of component groups are cooled by the same cooling circuit.

A combination of a gas turbine engine and a power electronics for powering aircraft and/or engine systems. The engine includes an engine core comprising a turbine, a combustor, a compressor, and a core shaft connecting the turbine to the compressor, and a fuel circuit for supplying a fuel flow to the combustor. The power electronics is configured to transfer heat produced by the power electronics to a cooling flow formed by a portion of the fuel flow. The fuel circuit is configured to circulate the cooling flow in a loop during selected engine conditions such that the cooling flow transfers heat from the power electronics to a phase change material located on the loop. The phase change material has a phase change temperature at a predetermined limiting temperature whereby the phase change material stores heat from the cooling flow to prevent the power electronics exceeding the limiting temperature.

An unmanned aerial vehicle (UAV) that includes a chassis and a gimbal module. The gimbal module includes at least one optical component that facilitates image capture, and is configured for removable connection to the chassis to facilitate repeated connection and disconnection of the gimbal module and interchangeability amongst a plurality of gimbal modules.

An unmanned aerial vehicle (UAV) that includes: a front chassis defining an intake port; a rear chassis defining an exhaust port and providing a heatsink for the UAV; and a blower that is located immediately rearward of the intake port so as to facilitate unobstructed airflow through the intake port and into the blower. The blower is configured to direct air through the UAV along an airflow path that extends from the intake port to the exhaust port to thereby cool the UAV.
