16.61 Aerospace Dynamics

Spring 2003

Course Highlights

This course on Aerospace Dynamics includes a complete set of lecture notes and assignments, as well as an extensive reference reading list. Topics extend to analysis of both aircraft flight dynamics and spacecraft attitude dynamics, based upon presented principles and equations of motion.

Course Description

This undergraduate course builds upon the dynamics content of Unified Engineering, a sophomore course taught in the Department of Aeronautics and Astronautics at MIT. Vector kinematics are applied to translation and rotation of rigid bodies. Newtonian and Lagrangian methods are used to formulate and solve equations of motion. Additional numerical methods are presented for solving rigid body dynamics problems. Examples and problems describe applications to aircraft flight dynamics and spacecraft attitude dynamics.
