**Course Objectives**:

The objective for this course is to develop an understanding of low-speed aerodynamics and an introduction to compressible flows. The course covers concepts in incompressible airfoil theory, including symmetric and cambered airfoils using analytical and numerical approaches. The course also covers incompressible wing theory, including down wash, lifting-line theory, elliptic wings, general twisted wings, application of fundamentals to the design of a wing to meet given performance criteria. Finally, the course covers topics in elementary gas dynamics, including expansion waves and shock waves, as well as thin airfoils in compressible flows.

**Course Outcomes**:

Students who successfully complete the course will demonstrate the following outcomes by tests and homework:

1. An ability to apply airfoil theory to predict airfoil performance.

2. An ability to analyze and optimize wing performance.

3. A knowledge of basic compressible gas dynamics.

4. An ability to apply principles of gas dynamics to solve compressible flow problems.

5. An ability to analyze airfoils at subsonic, transonic and supersonic flight conditions.

6. An exposure to recent developments in aerodynamics, with application to aerospace systems.

7. An ability to apply the concepts of aerodynamics to the design of aerospace systems.
