Course description and aims
The instructors will lecture on
1) attitude control of spacecraft
2) orbit control of spacecraft
3) structural dynamics of spacecraft and rockets.
Student learning outcomes
In this course, the basics of the following topics are lectured.
1) Attitude control of spacecraft: coordinate transformation, attitude representations, kinematics, dynamics, disturbance torque (gravity-gradient, solar radiation, electromagnetic and other torque), nutation of spin satellites, and various types of attitude control, such as control of gravity gradient stabilized satellites, stabilization control of spin satellites, control of three-axis stabilized satellites, attitude change control.
2) Orbit control of spacecraft: sphere of influence, patched conic method, interplanetary/cislunar orbits, three-body problems.
3) Structural dynamics of spacecraft and rockets: loads and dynamics for rocket and spacecraft structures and their design, design for mechanisms for spacecraft, basics of flexible deployable structure.
