A system allowing for the controlled propulsion of aircraft, especially buoyant and semi-buoyant airships designed as a symmetric body of revolution, without the need for or use of aerodynamic control surfaces, comprised of a plurality of ducted fan thrusters placed both fore and aft, designed to ingest air flowing at less than free stream velocity. Fans are arranged such that when at standard orientation, the thrust from each is directed tangentially to an arc drawn along the hull from bow to stem. By defining multiple sets of thrusters based upon their...
What I claim as my invention is: 1. A propulsion system for the controlled flight of buoyant and semi-buoyant aircraft comprising:a plurality of fans arranged such that each fan is positioned to ingest air moving at slower than the free stream velocity, such as near the bow and stern on an airship with a predominately symmetrical body of revolution hull shape;orientations such that each of the fan's thrust is directed along a line tangent to an arc drawn from bow to stern whereby the air stream produced by fans at the bow when in the forward thrust setti...
