ME 511 Aircraft Simulation and Control
The simulation of the dynamic movement of an aircraft is essential in its design. Within a project, it is necessary to verify the aerodynamic response of the aircraft to command inputs and also how its response changes with the incorporation of flight control systems. The behavior of an aircraft can be modeled using a set of nonlinear equations, resulting from the application of known laws of physics (Newton's 2nd Law, for example). The numerical integration of these equations is a mature and well-known process, and several numerical routines are available. Due to requirements in maneuverability, performance, radar signature, etc. several modern aircrafts have inherently poor flight characteristics. In addition, the extended flight envelope found in modern aircrafts does not allow satisfactory flight qualities at all operational points. To correct such deficiencies, the use of stability enhancement systems (SAS) is used. These systems adjust the frequencies and dampenings of an aircraft's dynamic modes. When it is desired to correct such deficiencies and also to provide the pilot with a certain type of control over the aircraft (for example, making a joystick entry match a load factor), control augmentation systems (CAS) are used. Finally, an autopilot can be implemented over SAS or CAS to ensure the aircraft returns to the original condition.
