Interactional Aerodynamics of the Single Rotor Helicopter Configuration. Volume II-E. Harmonic Analyses of Airframe Surface Pressure Data, Runs 15-22, Mid Section.

Abstract

This is the fifth of the nine-sub-volumes of Volume II. These documents contain harmonic analyses of the waveforms generated by each of the 53 pressure transducers, which covered the surface of the model fuselage and empennage. This sub-volume covers the second eight of the twenty-seven runs devoted to surface pressure testing. The analyses encompass the transducers in the middle section of the model. Test conditions and/or configurations include effects of root cut-out, vortex generators and strakes, autorotation, and rotor height. (Author)
