Interactional Aerodynamics of the Single Rotor Helicopter Configuration,Volume IV-A. One-Third Octave Band Spectrograms of Wake Split-Film Data,Buildup to Baseline.

摘要

This is the first 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 wake changes as the model is built up to the baseline configuration. (Author)
