By the completion of the course the students should be able to:
1. Perform coordinate transformations between different reference frames and discuss orthonormality of complex rotation matrices.
2. Derive orientation and rotation matrices of the aircraft-fixed reference frame with respect to the NED earth-fixed reference frame.
3. Derive the six DOFs translational and rotational kinematical aircraft equations of motion.
4. Apply the basic kinematical equation to obtain velocities and accelerations relative to earth-fixed frame and robotic and gyroscopic devices frames.
5. Express the aerodynamic, propulsive, and gravitational forces in the aircraft body fixed reference frame.
6. Define static and dynamic stability for a dynamical system and classify aircraft motions in terms of longitudinal and lateral degrees of freedom.
7. Derive small disturbance equations of motion, and identify longitudinal and lateral sets of equations, construct state space models for longitudinal and lateral aircraft dynamics.
8. Derive state space models for LTI multivariable mechanical systems and solve state space equations in time domain for linear decoupled dynamical systems.
9. Construct reduced state space models for Phugoid, short period, Dutch roll, spiral, and roll modes approximations and estimate the motion characteristics of each mode.
10. Describe the conditions of static stability and trim for a wing section, and determine the stick fixed neutral point and the stick fixed static margin for the aircraft.
11. Describe the effect of changing the center of gravity location on the aircraft longitudinal static stability and trim and compute the size of the elevator required to trim the aircraft during landing.
12.
Describe the conditions of aircraft lateral static stability and trim and estimate the contributions of wing, fuselage, and vertical tail to the aircraft lateral static stability.Key Student Outcomes assessed in the course: (a) and (e)
