TIME-DEPENDENT THRUST GENERATED BY A PROPELLER OPERATING IN A TURBULENT INFLOW

The broadband radiated sound of a propulsor can be related to the time-dependent thrust generated by the propulsor due to operation in a randomly varying turbulent velocity field. In order to understand better the radiated sound phenomenon. An experimental and theoretical investigation of the time-dependent thrust response of a propeller due to operation in turbulent inflows having various characteristic parameters was conducted. The experimental investigations employ an unsteady thrust balance mounted in the drive shaft of a 5-bladed free-stream propeller. Measurements of the time-dependent thrust generated by the propeller were made for turbulent inflows having a range of characteristics length scales and a range of turbulent intensity.
