Interactional Aerodynamics of the Single Rotor Helicopter Configuration. Volume VI-C. One-Third Octave Band Spectrograms of Wake Single Film Data, Hubcaps and Air Ejectors.

Abstract

This is the third of the three volumes of Volume VI containing one-third octave band spectrographs of the model helicopter hub/rotor wake velocities derived from the single-film velocity transducer data. This sub-volume deals with the effects of hub caps and air ejector systems on wake velocities. (Author)
