Aircraft for use as underwater vessel, has wings with space that is filled with atmospheric gas or light gas, where weight of aircraft is lighter and heavier than atmospheric gas in dependence of amount of inflated atmospheric gas

摘要

The aircraft has wings (2) filled with gas. The wings have a space that is formed with flexible partitions. The space is filled with atmospheric gas or light gas, where weight of the aircraft is lighter and heavier than the atmospheric gas in dependence of amount of inflated/pumped atmospheric gas. The aircraft is lowered through weight expansion by pumping/inflating of the atmospheric gas in the space, and through volume reduction of the space. An ellipsoid or drop-shaped balloon (1) and a tail control gear (4) are provided in the aircraft.
