Turbine Engine Rotor Dynamic Evaluation. Volume II. Engine and Test Rig Balancing.
Abstract
As an extension of the original AFAPL Contact for determining the rotor-dynamics characteristics of eight jet engines within the Air Force inventory, Mechanical Technology Incorporated performed balancing demonstrations to show the applicability of combining dynamic characteristics and advanced balancing techniques to effectively reduce the vibration of production type machinery. Trim balancing procedures were performed on the TF30, TF41 and F100 jet engines which are currently in use on military aircraft. A very sensitive hgh-speed experimental test apparatus called the 'Rub Rig' was also used to show the benefits of multiplane-multispeed balancing using influence coefficients. All the balancing operations were highly successful, and showed the potential for using this type of balancing system to increase manpower productivity, reduce operating cost, and to provide a precision balanced rotor for production or laboratory use.
