A transportation tooling structure, a split electric motor module with the transportation tooling structure, and a transportation method are provided. The transportation tooling structure comprises: a split base plate, a stator support and a rotor support, wherein the lower end of the stator support is fixedly supported on the upper surface of the split base plate, and the upper end of the stator support is fixedly supported on the side of a split stator close to the split base plate; and the upper end of the rotor support is fixedly supported on the side of an end of a split rotor away from the split stator, and the lower end of the rotor support is fixedly supported on the side of the split stator away from the split base plate.

Systems and methods for extending the interior cargo bay of fixed-wing cargo aircraft into a replaceable tailcone bay are disclosed. The system includes an aircraft and a removable tailcone configured couple to the aft end of the fuselage. The aircraft fuselage includes a cargo bay and an aft end opening into the cargo bay. The tailcone, when attached, encloses the aft end opening the cargo bay. The tailcone can include an interior volume configured to extend the fuselage cargo bay such that the interior volume defines an aft end of a cargo bay of the cargo aircraft. In some examples, the tailcone includes a plurality of segments, which can be configured to extend from the aft end of the aircraft to adjust a length of the cargo extension provided by the tailcone.
