[Problem] To universally realize a space structure (such as a space elevator) to which particular spacecraft, having significantly better propulsion efficiency than solar sail boats and not using rocket fuel (that is disposable and expensive), and the power units (continuous-perpetual airflow circulation) of such models have been applied. [Solution] Firstly, as shown, for example, in figure 1 and figure 2, in particular, propulsion bodies (two bodies having different shapes) are prepared, the propulsion bodies having applied thereto the pressure difference and wind pressure acting on both ends, and being moved by the wind pressure from a ducted fan. Sequentially, the two bodies (applying dynamic lift or the like acting on the vicinity of a hollow part of the inside the machine), without action and reaction forces canceling each other out, and moreover, and with the propellant (simply air gas) blown from one among the bodies being accepted (in-taken), without any spare, by another receiving body, move close together (closest together) overall, and are moved in parallel...etc. |
