Abstract
A fixture 39 for positioning shroud 22 of a rotor blade 14 with respect to an apparatus for inspecting the blade is disclosed. The fixture is formed of a base 42, locater means 40 attached to the base, first and second references 44, 46, a second locater 48 which engages the blade along a curved edge 50 at a hinged joint and measuring devices 64, 66 which are slidable rails having an axis e and an axis f. A method for inspecting the blades by orienting a shroud reference plane SRP with respect to the first and second reference surfaces is disclosed. In an alternate embodiment, the blade is rotatably supported about a flat surface and uses a surface on the root 18 for rotation. The fixture also includes a master block 68 to provide a self-mastering feature to the fixture.
