Flight Dynamics II
Flight Dynamics II (Stability). Instructor: Dr. Nandan Kumar Sinha, Department of Aerospace Engineering, IIT Madras. This course studies the motion of flying objects in air under the equilibrium condition. Topics covered in the lectures include: aircraft nomenclature and aerodynamics, equilibrium and stability, longitudinal static stick fixed stability, longitudinal stability and neutral point, longitudinal control, longitudinal control and Maneuverability. Lateral Directional Static Stability and Control. Equations of Rigid Aircraft six-degree-of-freedom motion, perturbed (linear) aircraft model, longitudinal dynamic modes, lateral-directional dynamic modes, aircraft response to external inputs, and introduction to aircraft control systems.
