International Classification:

B64B 1/12
B64B 1/08

Abstract:

In an embodiment, a system for synchronizing the rotation of multiple mainframes of an airship includes multiple belt drive systems configured to mechanically rotate the mainframes, a central control system for sending a timing instruction to cause the mainframes to rotate synchronously about their respective rotational axis, wherein the mainframes are axis-aligned about their respective rotational axes and the timing instruction specifies a desired angular displacement of the mainframes, and multiple control units for controlling the belt drive systems to rotate the mainframes, respectively, wherein, for each mainframe, the associated control unit is configured to: receive the timing instruction from the central control system; determine, according to the timing instruction, a rotation instruction based on a size of the mainframe and the desired angular displacement; and instruct the belt drive system controlled by the control unit to rotate the mainframe based on the rotation instruction.

B64B 1/08

Abstract:

A jig for constructing a mainframe of an airship structure, including multiple tracks configured in a radial pattern, each track including rails that are configured to be parallel to each other, multiple front carts for securing inner portions of the mainframe corresponding to an inner circumference of the mainframe, each front cart configured to be positionally adjustable along one of the tracks, and multiple back carts for securing outer portions of the mainframe corresponding to an outer circumference of the mainframe, each back cart configured to be positionally adjustable along one of the tracks.
