Interactional Aerodynamics of the Single Rotor Helicopter Configuration. Volume IIIB. Flow Angle and Velocity Wake Profiles in Low Frequency Band, Air Ejector Systems and Other Devices.

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)
