Bradley, W. G.2017-07-132017-07-131965-04http://dspace.lib.cranfield.ac.uk/handle/1826/12191This note describes the measurement of the moments of inertia in roll, pitch and yaw of a Hawker-Siddeley (de Havilland) Dove Mk. 5 aircraft, using a spring-restrained oscillation technique. Using the present equipment it did not prove possible to measure the product of inertia. Inertias mere measured in six different fuel conditions . The results are given in Tables I - V. A device was developed which measures the periods of oscillation of large structures, quicker and more accurately than hitherto possible. This device is described in the Appendix.enReport
