This set of experiments focuses on core principles of aerodynamics and fluid-structure interaction, typically conducted within a wind tunnel or similar flow bench apparatus. The primary goal is the empirical determination of forces and flow characteristics essential for designing efficient flying vehicles and structures. The analysis moves beyond simple force measurement to include detailed studies of the flow field, specifically focusing on the pressure variations over body surfaces, the nature of the boundary layer, and the structure of the wake downstream of the object. Furthermore, the inclusion of flow visualization techniques, particularly in conjunction with a fog generator, allows for the direct observation of streamlines, which is crucial for understanding complex unsteady phenomena like flutter.
