ABSTRACT:
This invention pertains to an automatic apparatus and method for determining the mass-moment of a blade of a jet engine. It encompasses an elongated weighing beam that is lifted up off both the weighing scale and a fixed fulcrum block during the loading and unloading of the blade with respect to the weighing beam. When measurements are to be taken, the weighing beam, with blade attached, is lowered onto the scale and the fixed fulcrum block. The value measured by the scale is sent to a computer for calculation of the blades' mass-moment.
