The GB series Moment Of Inertia (MOI) instruments are designed to measure large mechanical components such as re-entry vehicles, spacecraft, automobile engine parts, and complex structures.Standard
models are available for measurement of test objects weighing up to 15,000 pounds (6,800Kg) with an accuracy of +/-0.1 percent. In addition to their use as a design tool, these instruments are fast
enough for use on production lines for manufacturing quality analysis.Most rotating machinery and all space vehicles require the calculation of Moment of Inertia of components and complete
assemblies. While these calculations have become faster and more accurate through the use of computers, the exact value and extent of manufacturing variations cannot be known without making
measurements.Space Electronics GB Series instruments measure the MOI of any object regardless of its size or shape in a fraction of the time required for the MOI calculation and permit rapid
accumulation of data for variation analysis.
