<p>The inventive propulsive unit can be used as a motor or propelling device of the flapping wing variety. Said propulsive unit comprises, at least, one wing connected, with the aid of a root thereof, to a driving element, which performs a swinging and spherical motion by means of a crank-type joint fitted with two inclined cranks and mounted on a base of a driving shaft, and also by means of a supporting kinematic chain which links the driving element to the base. In order to increase the reliability of the supporting kinematic chain, said chain is embodied, at least in the form of two links e.g. a guide strip and a slipper. In addition, one link (for instance, the guide strip) is connected to a driven element, and the second link (for instance, the slipper) is connected to the base. The variants for embodying the supporting kinematic chains and developing a system fitted with the driving element combined with a casing (in terms of a wind engine) are also disclosed. The casing is provided with a skirt and encompasses the working shaft fitted with a gear wheel and a bevel pinion, and the skirt encompasses a tubular part of the base with the slipper mounted thereon and embodied in the form of a cylinder which interacts with the slide strip placed inside the skirt.</p> |
