SD2800 Experimental Aerodynamics 6.0 credits
This course has been cancelled.
Wind-tunnel testing is the traditional tool to determine the aerodynamic forces acting on an aircraft. In this course you will perform a number of tests, mainly to compare computational and experimental results when this is possible, but also to show that experimental methods can be used to determine aerodynamic forces in cases where computational results are inaccurate or impossible to obtain.

Intended learning outcomes
The aim with course is that you should learn how to plan, conduct, and process data from wind tunnel tests. You should develop increased understanding of basic physical phenomena and their influence on the performance of aircraft. Comparisons between experimental and computational results are used to gain experience concerning what type of investigations are most suitable for an experimental approach.
The overall objectives of the course are that you should be able to:
- decide which type of flight condition that is suitable for wind-tunnel testing,
- process, interpret and compile data from wind-tunnel testing,
- compare and combine computational and experimental aerodynamic data,
- explain phenomena like stall, hysteresis, separation and influence from boundary layers.
Course main content
The course is based on three projects. Each project is initiated by a general lecture on the topic of each project. This is followed by a group exercise where initial estimates are made and the actual test is planned. Then follows the actual wind tunnel test which is performed in small groups. Finally, a computer lab is performed where the test data is analyzed and processed.
The first project involves an investigation of a wing profile. Measurements are taken of pressure distribution, drag and lift forces. Visualization techniques are used to investigate boundary layer effects and their influence on overall wing profile performance. The second project concerns the measurement of integrated forces on a complete aircraft configuration, in this case the Swedish Air Force jet trainer Saab 105 (SK60). In the final project, the high angle of attack aerodynamics of the supersonic Saab J35 Draken is analyzed.
