Abstract : Selected experimental methods are analyzed to determine the accuracy required in the measurement of subsidiary quantities and the optimum magnitudes for those quantities in determining center of gravity locations and moments of inertia for wind tunnel models. The conclusions to which the analyses lead are tested by experimentally determining the moments of inertia and center of gravity positions of four missile models and a rectangular parallelepiped. It is shown that these parameters can be determined with an accuracy of 0.1 percent or better using ordinary laboratory equipment if the measurements are carefully made using optimum values of the various quantities involved.
