Abstract

An electric conduction structure for conducting and diverting electric current from a vane main body of an cutlet guide vane into en exterior support structure is comprised of: a sheath of a metal covering a leading edge of the vane main body; and an electrically conductive pad of the metal comprising a contact portion so dimensioned as to have an overlap with an end of the sheath, and a washer portion into which a bolt for being tightened into the support structure is insertable, wherein any joints of a weld, a spot-weld, a solder, a bond by an electrically conductive paste and a crimp establish connection between the end of the sheath and the contact portion.

First claim

What is claimed is:

1 . An electric conduction structure for conducting and diverting electric current from a vane main body of an outlet guide vane into an exterior support structure, comprising:
a sheath of a metal covering a leading edge of the vane main body; and an electrically conductive pad of the metal comprising a contact portion so dimensioned as to have an overlap with an end of the sheath, and a washer portion into which a bolt for being tightened into the support structure is insertable, wherein any joints of a weld, a spot-weld, a solder, a bond by an electrically conductive paste and a crimp establish connection between the end of the sheath and the contact portion.

2 . The electric conduction structure of claim 1 , wherein the metal is any of titanium, titanium alloys, nickel, nickel alloys, and stainless steels.

3 . The electric conduction structure of claim 1 , wherein the overlap has a width of 1 mm or more and a length of 10 mm or more.

4 . The electric conduction structure of claim 1 , further comprising:
an electrically conductive wire interposed between the sheath and the vane main body and electrically connected with the electrically conductive pad.
