<p>The blade (21) has a guide edge (25) consisting of lines and/or curves, which have different angles of inclination to a straight line between a blade head and a blade root. The blade is arranged in such a way that flow of gas and/or vapor does not hit on edges that are continuous and straight over blade length, and hits on differently inclined edges per blade for flow. The flow of gas and/or vapor is bounced on edges (26) of the blades with a supersonic speed. Nozzle walls (11) and/or guide vanes are provided at turbines.</p> |
