- Summary:
- This note deals with the mass distribution and performance of free flight models. An airplane model which is to be used in free flight tests must be balanced dynamically as well as statically, e.g., it must not only have a given weight and the proper center of gravity but also a given ellipsoid of inertia. Equations which relate the motions of an airplane and its model are given. Neglecting scale effect, these equations may be used to predict the performance of an airplane, under motion of gravity alone, from data obtained in making dropping tests of a correctly balanced model.
- It is shown how a light model, built with little regard to its mass distribution, may be loaded with masses of predetermined weight, shape, position and attitude to give the distribution desired.
- It is indicated how this method of distributing the mass in a body to obtain a desired distribution, together with the model dropping tests may be used to determine the most desirable inertia characteristics of an airplane of given shape.
