Hypersonic Aerodynamics (45817)
2nd Semester 91-92
OBJECTIVE: Develop an understanding of inviscid hypersonic flows, viscous hypersonic flows and high temperature effects as they apply to hypersonic aerodynamics.
Text Book: Anderson, J. D., Hypersonic and High Temperature Gas Dynamics, McGraw Hill, 1989.
Homework: Assignments are made approximately weekly, due in one week for the text problems and two weeks for the instructor’s one. Late penalty is 5% per calendar day, No homework accepted after graded one is returned.
Quizzes: A 10 minute quiz will be given randomly.
Grades:
| Homework and quizzes | 30% | |
| Midterm | (00/00/00) | 25% |
| Final | (92/03/25) | 40% |
| Project | 10% | |
| Total | 105% |
