A drone includes a frame and a battery. The frame has a battery accommodation groove. The battery accommodation groove includes a first positioning component and a second positioning component. The first positioning component and the second positioning component are staggered along a first direction. The battery is received within the battery accommodation groove. The battery has a first positioning portion and a second positioning portion. The first positioning portion is matched with the first positioning component, and the second positioning portion is matched with the second positioning component. Therefore, an automatic exchange of batteries along the first direction can be implemented, and the advantages of reducing costs of space, time, and manpower can be achieved.

A system for lifting and transporting an aircraft comprising a movable platform, a lower lift system, and a first pair of wheels. The platform comprises a frame having an upper and a lower surface and a plurality of hook ups. The lower lift system is configured to raise the platform and an aircraft supported by the frame. The lower lift system comprises a lifter selected from the group consisting of: at least one hydraulic jack, at least one pneumatic jack, slots for forklift arms, at least one inflatable airbag, and combinations of any or all of the foregoing. The first pair of wheels are coupled to or configured for coupling to the frame so that the raised platform with an aircraft supported by the platform can be transported. A method of using the system comprises positioning the system beneath an aircraft and lifting the platform and the aircraft.

A powerplant system is provided that includes a gas turbine engine system and an actuation system. The gas turbine engine system includes a rotating structure, a stationary structure and one or more bearings rotatably mounting the rotating structure to the stationary structure. The actuation system is configured to passively rotate the rotating structure about a rotational axis during transportation of the gas turbine engine system.

Systems, devices, and methods for a ground support system for an unmanned aerial vehicle (UAV) including: at least one handling fixture, where each handling fixture is configured to support at least one wing panel of the UAV; and at least one dolly, where each dolly is configured to receive at least one landing pod of the UAV, and where each landing pod supports at least one wing panel of the UAV; where the at least one handling fixture and the at least one dolly are configured to move and rotate two or more wing panels to align the two or more wing panels with each other for assembly of the UAV; and where the at least one dolly further allows for transportation of the UAV over uneven terrain.

Disclosed herein is a system for lifting an object. The system comprises a first floor, a second floor, and an object rack supported on the second floor. The system further comprises an object advance apparatus coupled with the object rack. The object advance apparatus is configured to advance one object from the plurality of objects from an advancing position to a lifting position. The system additionally comprises a lifting cylinder that is configured to extend from a retracted position below the lifting position to an extended position above the first floor, such that the one object in the lifting position is removed from the object rack and lifted adjacent to the assembling body. The system also comprises a floor flap configured to open and close in synchronization with the extension and retraction of the lifting cylinder.
