Available in PDF, EPUB and Kindle. Book excerpt: In the past, the computation of aircraft spin conditions required the use of a six degree of freedom program. In this paper a simple procedure was developed by using approximations for predicting spin values. This method required only one force (normal) and one moment (spin about the vertical axis). A simple algebraic equation was derived for the spinning moment in which the roots produced the spin conditions. Three fighter aircraft were analyzed and two stable equilibrium spin points were determined for each aircraft (flat and steep). Comparison with results of previous six degree of freedom analysis showed good agreement with this simple procedure.
