INERTIA CALCULATIONS}, address = {Seattle, Washington}, abstract = {This paper was presented at the Twenty-first Annual National Conference of the Society of Aeronautical Weight Engineers at Seattle, Washington, May 14-17, 1962. The purpose of this paper is to furnish the engineer with a method for rapidly and accurately estimating the moment of inertia of manned aircraft during the advanced design period. Such inertias are needed so that dynamic load and stability characteristics of the aircraft may be evaluated. To evolve a method which would not be limited to any particular type of aircraft, empirical data were gathered from many types of combat and transport aircraft and combined with the results of a mass distribution parametric study. By this method, the moment of inertia for a complete aircraft can be computed with a total expended time of about three man hours. The prerequisite data needed are a group weight and balance statement, a three view drawing, and some knowledge of the design characteristics of the airplane. As with all procedures and methods based on empirical data, extrapolations by this method are limited to aircraft within the present state of the art. As advancements in the state of the art occur which significantly affect weight distribution, the method should be altered accordingly. }, keywords = {05.
