Pu00c1 for turbine eu00d3lica with low emission of noise in urban environment.

摘要

The present invention relates to a turbine eu00d3lica horizontal axis (1), with a root (7), one end (8), a leading edge (9), a trailing edge (10), a extradorso convex (11) and a soffit (12) cu00d4ncavo, convex or in the form of a the form of the 's'.It is characterized by construu00cdda with a single profile with modification of its line media to satisfy a load distribution profile along the axial cord of the pu00c1, with reduction of the peak pressure in the section of the pu00c1 to high angles of impact of flow and r. Pressure ecuperau00c7u00c3o smooth from the point of maximum suction and the trailing edge of the profile.This profile is constituu00cddo by sections (17) along the wingspan, built from a set of dimensionless coordinates, with a coefficient of maximum pressure of 1.5 and reduced emission of noise from aerodynamics.In the X / C and Y / C are dimensionless coordinates that correspond to the coordinates and dimensions of the profile of the section of the real pu00c1 divided by the length of the rope of the same 'C' used for the construction of a profile aerodinu00c2mico (17).
