System for space propulsion and space loitering (above-stratosphere air loitering)

摘要

To achieve a special spacecraft (flying aircraft) having propulsion efficiency that is several times (several orders of magnitude) greater than that of a solar sailcraft and the like, and requires practically no disposable (in space) and expensive rocket fuel or the like, and also to achieve a stratospheric flying aircraft capable of loitering. The present invention applies the difference in pressure (internal pressure) acting on wall surfaces (inner walls) or the like at both ends of a propulsion module body (aerial body) in space where there is no atmosphere or the like. Specifically, the present invention adopts a propulsion method as set forth in the claims.
