Interactional Aerodynamics of the Single Rotor Helicopter Configuration. Volume IV-D One-Third Octave Band Spectrograms of Wake Split-Film Data,Open Hubcaps.

摘要

This is the fourth of the seven sub-volumes of Volume IV containing one-third octave band spectrographs of the model helicopter hub/rotor wake as it was modified by various aerodynamic devices. This sub-volume deals with the effects of various open hubcaps. Open caps have parallel undersides and uppersides. (Author)
