Air Breathing Propulsion

AAE53800

Credit Hours: 3

Learning Objective:
1. Understand principles of operation of turbojet, turbofan, and turboprop engines. 2. Develop the ability to analyze complex one-dimensional compressible flow phenomena. 3. Develop the ability to perform fundamental component design and analysis. 4. Develop the ability to perform component matching . 5. Develop the ability to predict on-and off-design operating points for an engine.

Description:
Analysis of operating characteristics of turbojet, turbofan, turboshaft, afterburning, and ramjet propulsion systems. Analysis and design of inlet, diffuser, combustor, compressor, turbine, nozzle. Component matching and off-design performance for steady-state and transient operating lines. Inlet distortion, nozzle-afterbody, and installation losses.

Topics Covered:
Fundamentals of 1-D compressible flow, Turbomachinery cycles, Performance criteria and component efficiencies, Turbojet and turbofan cycles, Component characteristics, Equilibrium line and off design matching, Single spool matching, Dual spool matching, Turbofan matching, Engine acceleration/deceleration, Compressors, Combustors, Turbines, Inlet systems.

Prerequisites:
Thermodynamics, fluid mechanics, aerodynamics.

Applied/Theory: 50/50

Web Content:
Syllabus, grades, lecture notes, homework assignments and solutions.

Homework:
Homework assignments range from traditional homework problems to mini-projects. Will typically be one assignment a week. Absolutely NO late homework will be accepted for any reason. However, your lowest homework score will be discarded. Homework will be accepted via email (Faculty or TAs email).

Projects:
Required. Mini-projects will involve topics such as coupled component analyses, off-design gas turbine matching, and inlet/isolator matching and will typically require computer solution; often involving fairly complex iterative procedures.

Exams:
1 midterm exam and 1 final exam.

Textbooks:
Official textbook information is now listed in the Schedule of Classes. NOTE: Textbook information is subject to be changed at any time at the discretion of the faculty member. If you have questions or concerns please contact the academic department.

Computer Requirements:
ProEd Minimum Computer Requirements. Homework will often require computer solution and plotting and will entail parametric computation of representative application problems as well as the development of a 'matching deck' for single spool gas turbine engines. Matching will require iterative solution. Representative iterative methods will be discussed in class and example coding (matlab) for iteration control will be supplied by instructor. Typically matlab is sufficient, but the student can use Fortran, C or other according to their preference.
