Aircraft Stability and Control

Overview

Explore the fundamentals of aircraft stability and control in this comprehensive course. Delve into static stability, longitudinal control, directional stability, lateral stability, and handling qualities. Learn about stick-free stability, hinge moments, and aircraft equations of motion. Examine small perturbation theory, dimensional stability derivatives, and dynamic stability. Investigate longitudinal modes, short period and phugoid approximations, and stability augmentation systems. Cover lateral-directional motion and gain insights into the history of aviation. Engage with practical problems, numerical exercises, and tutorials to reinforce your understanding of these critical aspects of aeronautical engineering.
