The mass moments of inertia of an aircraft are required for use in the accurate evaluation of dynamic, stress, and flutter conditions to which an aircraft may be subjected. Mass moments of inertia are used in the dynamic sense to predict angular accelerations resulting from externally applied torques, and in the determination of stresses produced in the aircraft structure by these accelerations. The distribution of the moment of inertia is used in conjunction with the rigidity of the structure to evaluate potential flutter conditions.
Rotational inertia loads play an important part in the design of certain types of aircraft. Because of the increasing performance demands on these aircraft and the resulting, more refined techniques of dynamic and structural analysis, it is necessary to determine the values of the moments of inertia within a reasonable degree of accuracy. This paper offers information which will be of aid in the computation of the mass moments of inertia of aircraft. It has been written as an aid to the training of weight personnel. Also, it is hoped that paper will cause other groups to become cognizant of the problems encountered in the calculation of the moments of inertia.
