The Influence of very heavy fuselage mass loadings and long nose lengths upon oscillations in the spin /

This report presents a chart showing the results of a study to determine those factors of airplane design and mass characteristics which influence the tail spin in such a manner as to make the spinning motion a series of violent rolling and yawing oscillations. This chart shows an empirical relationship between long fuselage nose lengths (side-area moment factor) and large distributions of mass along the fuselage (negative inertia yawing-moment parameters). This relationship separates a region for which steady spinning motions were obtained from a region for which violent oscillatory motions were obtained.NACA TN No. 1510."January 1948."Includes bibliographical references.This report presents a chart showing the results of a study to determine those factors of airplane design and mass characteristics which influence the tail spin in such a manner as to make the spinning motion a series of violent rolling and yawing oscillations.
