Abstract:

The addendum reports the results of an extension to the study to determine the time varying flow in the vicinity of a helicopter rotor in hovering and forward flight and having a fuselage immersed in the rotor wake. The purpose of the extension was to compare two models representing the fuselage. The first fuselage model AD-629 782 and AD-629 783, was based upon the assumption that the fuselage was immersed in a constant and uniform flow the second model was based upon the assumption that the fuselage was immersed in a constant but nonuniform flow. Comparisons between the two models are presented. Program listings and operational information related to the programs are given.
