Offered Spring
Pre-requisite AAE 43900 and AAE 37200
Course Instructor Professor Heister
Text There is no formal text for the class. However, several books have been placed on reserve in the Engineering Library:
  • Curran, E. T. and Murthy, S.N.B., Scramjet Propulsion, 2001
  • Murthy, S.N.B, Developments in High-Speed Propulsion, 1996
  • Murthy, S.N.B., and Curran, E. T., High-Speed Flight Propulsion Systems, 1991
  • Heiser, W.H. and Pratt, D. T., Hypersonic Airbreathing Propulsion, 1994.
These are all part of the AIAA Progress in Astronautics and Aeronautics series.
Assessment method Homework 20%, Midterm Exam 30%, Final Design Project 50%
Homework All assignments will be due at the beginning of class.  No late assignments will be accepted for any reason.
Exams A two hour midterm will be scheduled during the evening.
Student lectures The class will be subdivided into teams who will each provide a lecture in aspects related to hypersonic propulsion systems.
Final design project Each of the teams will submit a final report providing a detailed design of a hypersonic propulsion system. The report should contain sufficient detail to identify the flow conditions at all stations within the device – more details on the final project to follow.

Grading policy is an Instructor option and may vary.
