WebThe acoustic analogy is used to derive far-field radiation equations for high-speed propellers in flight via a helicoidal surface representation of the blades. The linear thickness and loading sources and the nonlinear quadrupole sources are steady in blade-fixed coordinates. Blade sweep and off set (bending normal to the chord) appear explicitly as phase lag …
