Aircraft Dynamic Stability and Design Stability Augmentation System

Aircraft Dynamic Stability and Design Stability Augmentation System. Instructor: Professor A. K. Ghosh, Department of Aerospace Engineering, IIT Kanpur. This course is designed to understand aspects of advance dynamic stability of an airplane. This course will also help in creating a background to design an airplane from stability and control aspects. Topics covered include Dynamic stability, Spring-mass-damper system, Pitch dynamics, Aircraft rigid body equation of motion, Six degree of freedom equations of motion, Forces and moments on aircraft, Euler angles, Small perturbation theory, Dimensional stability derivatives, Longitudinal dynamic stability, Lateral directional stability derivatives, Spiral and Dutch Roll mode approximations, Routh-Hurwitz stability criterion, and Stability augmentation system.
