Abstract: FIELD: land, water, air and space transport. SUBSTANCE: action of traditional propulsors (wheels, air and water propellers) is based on repulsion from surrounding medium and cannot operate outside this medium. Jet engines (propulsors) do not depend on surrounding medium and can work in space but their efficiency is low and they work on fuels which create thrust through exhaust of combustible products. They cannot be actuated by electric or atomic energy. Such propulsors are located on the outside of transport facilities and are not protected against external action. Given invention excludes these disadvantages. Device has crank-shaft and leverage system in which levers are connected by means of connecting rods. Rotary motion of crankshaft is converted into swinging motion of levers carrying ballast weights which create centrifugal forces at curvilinear motion; centrifugal forces are directed towards motion and when they are summed up, they form thrust of transport facility. This thrust is internal and is independent of outside medium. Propulsor is arranged inside transport facility and may be set in motion by means of internal combustion engine, electric motor and steam power plant working on nuclear fuel. When this device is used in helicopter, for example, there is no need to use massive and vulnerable rotors, offside tail unit; helicopter may be made in form of sphere or plate. EFFECT: enhanced maneuverability of transport facility and possibility of flying in Earth atmosphere and in space.
