Abstract:

This is the second of the two sub-volumes comprising Volume III. These documents present profiles of the RMS values of the wake flow angles and velocities in the 1 Omega to 2 Omega range. The format is waterline on the ordinate and velocity or flow angle on the abscissa. Each graph shows a comparison of the baseline flow to the flow modified by some device or condition. This sub-volume covers air ejector systems, air ejectors and hub caps in same configuration, wings, fairings and miscellaneous devices. Author
