Interactional Aerodynamics of the Single Rotor Helicopter Configuration. Volume VII-D. Frequency Analyses of Wake Split-Film Data, Open Hubcaps.

Abstract

This is the fourth of seven sub-volumes of Volume VII containing 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 hub caps. Open caps have parallel undersides and uppersides. (Author)
