VIBRATIONAL DAMPENING ELEMENT AND ROTOR BLADE

A vibrational dampening element (300) is attached to a component and configured to adjust the amplitude of oscillations of the component. The vibrational dampening element (300) includes a mass (308). The mass (308) includes a main body (310) and a member (312) extending from the main body (310). A...

Beschreibung
Zusammenfassung:	A vibrational dampening element (300) is attached to a component and configured to adjust the amplitude of oscillations of the component. The vibrational dampening element (300) includes a mass (308). The mass (308) includes a main body (310) and a member (312) extending from the main body (310). A casing (306) that encapsulates the mass (308). A fluidic chamber (309) defined between the mass (308) and the casing (306). A first fluidic portion (318) is disposed between a first side of the mass (308) and the casing (306). The first fluidic portion (318) includes a first accumulator portion (324) directly neighboring the member (312). A second fluidic portion (328) is disposed between a second side of the mass (308) and the casing (306). The second fluidic portion (328) includes a second accumulator portion (334) directly neighboring the member (312). The first accumulator portion (324) is in fluid communication with the second accumulator portion (334). The vibrational dampening element (300) further includes a primary passage (362) that extends between the first fluidic portion (318) and the second fluidic portion (328).
