Flight Dynamics and Control

Flight Dynamics and Control (EAS309)

Synopsis

The course aims to provide students with an understanding of the principles of flight dynamics and the problems of controlling an aircraft in motion. In the first part, the equations of motion for a rigid body aircraft and the aerodynamics forces and moments are examined. Dynamic stability and response characteristics are defined along with the effects of structural flexibility upon the motion of an aircraft. Flying and handling qualities of an aircraft, and disturbances affecting its motion are next developed. Finally, fundamentals of aircraft feedback control system design and analysis are introduced and stability augmentation and automatic flight control systems are described.

Level: 3
