Wake Imaging System Applications at the Boeing Aerodynamics Laboratory

The wake imaging system (WIS) for rapid mappings of wind tunnel model flowfields is described and a summary of recent results is presented. Three different types of systems are discussed. These are:

• Photographic WIS in low-speed wind tunnels.
• Computer graphics WIS in transonic wind tunnels.
• Flying strut traverser for large low-speed wind tunnels.

In addition, progress toward developing a low intrusive WIS for high-pressure transonic wind tunnels and for flight test applications is described.
