BLADES FOR SILENT TURBINES CHANGING THEIR POSITION IN THE ENVIRONMENT FLOW

摘要

1. Blades rigidly or movably fixed on the working planes of the turbines, which perceive the load from the flow of the medium and transmit it through the shafts to the energy mechanisms, have additional devices for turning their plane, increasing or decreasing the load on the plane of the blades from the flows of the medium, differing in that the rigid the blade consists of two shoulders of different sizes, the large shoulder perceives the power load of the flow, and the smaller shoulder serves as a support in the working position, and determines the calculated inclination between the support and working plane of the blade, approximately 80-90 ° from the side of the medium pressure, and in an obtuse angle bending the blade, an axial bushing is installed, attached to the plane of the replaceable element or the plane of the turbine, which makes it possible to rotate the blade when the medium flow pressure on it in the operating position or to automatically fold the blade when the flow pressure is removed or the blade enters counterflow. ! 2. Blades for low-speed turbines, changing their position in the flow of the medium, characterized in that a rotating roller is attached to the outer end of the rigid blade, provided that the blade is used in an aqueous medium. ! 3. Blades for low-speed turbines, changing their position in the flow of the medium according to the option, characterized in that the elastic blade in the form of a fabric "pocket" is attached on three sides to the outer plane of the turbine of any shape or to the plane of the replaceable element, and the open side of the "pocket" directed against the stream. ! 4. Blades for low-speed turbines, changing their position in the flow of the medium, characterized in that the elastic (tissue) blade in the form of a "pocket" in the front, along the contour, has an elastic
