Some Theoretical Developments in Airplane Static Longitudinal Stability and Control

Abstract

In this report, theoretical methods are developed for predicting some static longitudinal stability and control characteristics of airplanes from their basic geometry. The concepts of the stick-fixed, stick-free, and maneuvering neutral points are established and methods given for their evaluation. Methods for finding these neutral points from flight tests are discussed briefly, and the results of some calculated propeller-off neutral points compared against wind-tunnel tests. Finally, an example is worked out in detail to demonstrate the methods developed herein.
