Abstract

The present invention refers to a device which accelerates the fluid (in which the device is immersed) differentially immediately below and immediately above a surface (1). This acceleration can be obtained through a convergent/divergent channel, resulting in a greater fluid velocity in one of the faces of the surface. As greater speeds means lower pressures, there is a resulting force acting upon the surface. This force can be used to lift airplanes, helicopters, autogyros, or other aircraft in the air. Also it can be used to power sailboats, being a suitable replacing for the traditional sails. The convergent and divergent channels can assume several configurations, the two main categories being: a convergent (or divergent) channel in which the convergence occurs in the cross-sectional plane; and a convergent (or divergent) channel in which the convergence occurs in the horizontal plane, thus requiring a 3D geometry to represent the device. The former is illustrated in figures 1-5, while the later in figures 7-12. The concept object of this invention can also be used to design an aerodynamic brake, in which the low pressure jet stream leaving the convergent channel (11) can be blown over the top of the structure (12), thus increasing the drag force.
