Multi-engine drive configuration for spherical airships to improve the propulsion efficiency

摘要

It is indeed, a spherical of motor-driven aerosol with a plurality of spatially distributed, rigidly mounted on the surface structure and preferably provided with propellers drive units, in which the individual backwash are directed in such a way that they have had behind the moving aerosol in the wake of the flow converge. By means of burst transfer of the high-energy backwash on the low-energy wake on the lee side of the ball, the wake flow in the sense of an air resistance reduction of the aerosol is favorably influenced by. In addition, by means of individual control of the shear forces of the individual drive units a variation of the resulting thrust vector in the sense of a sides - and height control without the aid of additional mechanical control elements causes.
