TRAILING EDGE OF ROTOR BLADE Russian patent published in 2017 - IPC F03D1/06 F03D13/00 

FIELD: machine engineering.

SUBSTANCE: method for calculating trailing edge for a rotor blade of a wind-driven powerplant aerodynamic rotor to be manufactured. The rotor blade has radial positions relative to the rotor, the rotor blade has a local blade profile depending on the radial positions relative to the rotor, and the trailing edge has a toothed passage with a plurality of teeth. Each tooth has tooth height and tooth width, and tooth height and/or tooth width is calculated depending on its radial position and/or depending on the profile of the blade of its radial position.

EFFECT: reduced noise effects.
