<p>A ram air turbine assembly (10) includes a preferentially located mass (20,32,38,40,52,70,90) that modifies the resonance frequency of the assembly so that vibration is reduced to desired levels. The example mass can be fixed in a specific location on the ram air turbine or can be deployable once the ram air turbine is moved to an operating position.
