Airship

Abstract

A plurality of bulkheads (23a to 23d) are installed in a hull (21) so as to divide the interior space of the hull (21) into a plurality of compartments (ΔS1 to ΔS5) successively arranged along the axis (22) of the hull (21). The compartments (ΔS1 to ΔS5) are divided into upper flotation gas containing spaces (25a to 25e) and lower air containing spaces (26a to 26e) by flexible diaphragms (24a to 24e) impermeable to air and a flotation gas, respectively. The bulkheads (23a to 23d) have upper parts A1a, A1b, A1c and A1d formed of a meshed sheet, extending upward from joints (27a to 27d) of the diaphragms (24a to 24e) and the bulkheads (23a to 23d), exposed to the flotation gas containing spaces (25a to 25e). The upper parts are provided with a plurality of vents through which the flotation gas is allowed to flow.
