Method of shaping an edge of an aerofoil

摘要

An apparatus for shaping an edge of an aerofoil, the apparatus having first and second brushes and each brush having a plurality of bristles. A first motor rotates the first brush about a first axis and a second motor rotates the second brush about a second axis. The axes are arranged substantially parallel to the bristles of the respective brush. A support structure holds the first brush such that the first axis intersects a first surface of the edge of the aerofoil and holds the second brush such that the second axis intersects a second surface of the edge of the aerofoil. There are means to produce relative movement the first and second brushes and the aerofoil such that the first and second brushes move longitudinally along the edge of the aerofoil to shape the edge of the aerofoil.

1. A method of shaping an edge of an aerofoil, the method comprising:—
a) providing a first brush and a second brush, each brush comprising a plurality of bristles extending substantially parallel to each other, b) rotating the first brush about a first axis and rotating the second brush about a second axis, the first axis being arranged substantially parallel to the bristles of the first brush and the second axis being arranged substantially parallel to the bristles of the second brush, c) arranging the first axis to intersect a first surface of an edge of an aerofoil and arranging the second axis to intersect a second surface of the edge of the aerofoil, d) moving the first brush such that the first brush contacts the first surface of the edge and moving the second brush such that the second brush contacts the second surface of the edge, e) producing relative movement between the first brush and the second brush and the aerofoil such that the first brush and the second brush move longitudinally along the edge of the aerofoil to shape the edge of the aerofoil.
