Being the camber aerofoil in order to use for the camber aerofoil

摘要

The camber wing of this invention is formed in order to use inside the vane equipped turbocharger, adjoins to the turbine wheel and inside being arranged, outside being arranged on opposite side of the surface of wing and the inside surface of wing, has with the surface of wing. Inside and the outer part surface of wing forms blade thickness. The leading edge namely the nose of the camber wing is arranged, inside and paralleling to the 1st joint of the outer part surface of wing, the trailing edge of the wing is arranged, inside and paralleling to the 2nd joint of the outer part surface of wing. Inside the wing and the outer part surface of wing is formed as had the camber line of the wing which possesses the curve part, especially. Especially, the bend of the camber line of the wing gives the gas flow distribution which is improved, with that the effective operating range of the turbocharger in order to increase, is defined inside fixed tolerance by the arrangement diameter or pivot diameter of the wing which is measured, between the wings of diameter direction opposite side of the wing which normally, is installed in the turbocharger, it possesses curvature size.
