### Fundamentals of Propulsion (45117)

#### 2nd Semester 91-92

**Instructor:**M. Farahani

**OBJECTIVE:**The course is intended to serve as an introduction to airbreathing propulsion systems. Students are given a basic background in combustion, one-dimensional compressible internal flows. In addition, the students are provided with more detailed discussion of the major components in an airbreathing engines ranging from inlets and compressors to combustors, turbines, and nozzles.

**Text Book:**Hill and Peterson, Mechanics and Thermodynamics of Propulsion, (2nd Edition), Addison Weslay, 1992.

**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.
