This book was released on 1974 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report reviews and evaluates current practices for experimentally determining airplane center of gravity, moments of inertia, and products of inertia. The techniques discussed are applicable to bodies other than airplanes. In pitching- and rolling-moment-of-inertia investigations with the airplane mounted on and pivoted about knife edges, the non-linear spring moments that occur at large amplitudes of oscillation can be eliminated by using the proper spring configuration. The single-point suspension double-pendulum technique for obtaining yawing moments of inertia, products of inertia, and the inclination of the principal axis provides accurate results from yaw-mode oscillation data, provided that the sway-mode effects are minimized by proper suspension rig design. Rocking-mode effects in the data can be isolated. The conduct of the experiments, as well as the test setup used, is a major factor in obtaining accurate results.

This book was released on 1948 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: A coompound-pendulum method which eliminates the necessity for locating the center of gravity of the airplane by direct measurement is described. The pendulum length is found by measuring the difference between two suspension lengths and solving the equations for the two suspensions simultaneously. Experimental data and a precision analysis are included.

Available in PDF, EPUB and Kindle. Book excerpt: The application and results of the above method in ground oscillation tests are described. The various corrections to reduce the measured moment of inertia to the reference axis moment of inertia are presented. The results show that measurement of moment of inertia by this method is practicable, provided the knife edges and spring are arranged to minimize excitation of structural modes.

This book was released on 1954 with total page 718 pages. Available in PDF, EPUB and Kindle. Book excerpt: The angle of inclination of the principal axis was found to have probable error of plus or minus 0.17 degrees both from analysis of the error of inertia measurement of the full-scale airplane and from tests with a model having a simple configuration. Analysis showed the probable error of the inertia measurements for the test airplane to be plus or minus1.00, plus or minus 0.49, and plus or minus 0.35 percent of the true moment of inertia about the X, Y, and Z body reference axes, respectively.
