Abstract:
1. A lift generating device for enabling vertical fligh t comprising: a first revolution structure having a funnel shape and including a circular open surface and an open stem; a second revolution structure having a funnel shape and including an open surface and an open stem, the second revolution structure attached to the first revolution structure by a plurality of connectors and spaced therefrom so as to form a gap of a size sufficient to provide a selected air flow velocity between the first revolution structure and the second revolution structure; a propeller coupled to an open stem at a bottom end of the first revolution structure, the propeller being disposed between the first revolution structure and the second revolution structure; and a motor operatively connected to the propeller to provide power for the propeller to suction air into the lift generating device such that a pressure difference is created so as to generate an upward directed force.
