  Description:     The dynamics of vehicles that fly in a gas of sorts, usually air but also mars atmosphere and other.

 

Objective:        This course will provide you with extensive information about

                        the classical and the nontrivial aspects of flight. By the end of this course you will know: The classical nomenclature to describe vehicle flight; the nonlinear equations that describe flight vehicle dynamics; elementary vehicle stability concepts; vehicle linearized dynamics at cruise and trim; longitudinal modes; lateral-directional modes; system reaction to actuators: adverse yaw; aileron inversion issues; linearized dynamics in other conditions than straight and level flight; supersonic flight; gyroscopic effects; aeroelastic behaviors ;high angle-of-attack dynamics; wing rock; vehicle stall: Stall equilibria, including deep stall for T-tail designs; recovery from stall; spin: inception, fully developed spin, recovery, flat spin;

 

How:               By means of lectures and a continuing project.
                        The continuing project will determine your grade. I will feel free to give                             kudos in the form of bonus points to those of you who deserve them
