Download or read book A Method for Measuring the Product of Inertia and the Inclination of the Principal Longitudinal Axis of Inertia of an Airplane written by Robert W. Boucher and published by . 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.
