SISTEMA DI ASPIRAZIONE E DI SPINTA APPLICABILE PER SOSTENTAMENTO E PROPULSIONE DI AEROMOBILI PER SPINTA E FRENATA DI VEICIOLI TER RESTRI E NAVALI E PER ALTRE APPLICAZIONI

摘要

A fluid flow device comprises a rotor housed in a casing having slot-like intake and outlet openings. Groups of such devices can be used to form an aircraft propulsion system by drawing-in air from above through the intake openings and forcing the air downwardly through the outlet openings to provide lift and horizontal thrust, the effect being similar to that produced by the wing of a bird.
