Higher Harmonic Circulation Control Rotor Model - Model Instrumentation and Data Acquisition.
Abstract
A higher harmonic circulation control rotor was tested in the 8' x 10' subsonic wind tunnel at various advance ratios, blade tip Mach numbers, blowing air pressures, shaft angles and collective angles. The model was instrumented with strain gages, pressure transducers, thermocouples, magnetic pick-ups and a pitch-roll trim resolver. This information was recorded on an analog to digital acquisition system and on F.M. tape recorders for later digitization. The purpose of the report is to provide descriptive documentation of the model instrumentation and data acquisition portion of the test, and there is no attempt made to elaborate on helicopter or higher harmonic theory.
