Abstract:

The report summarizes the results of a test program conducted to record the unsteady pressures produced at a rigid boundary by the impingement of the wake from a model helicopter rotor. The recorded data consist of oscilloscope photographs of the pressure pattern for various rotor altitudes, disk loadings, collective-pitch angles, and pressure-transducer locations. Author
