Abstract
A tunable blade assembly for a flight vehicle includes a hub rotatable about a central axis. The tunable blade assembly also includes a blade extending along a longitudinal axis between a root end and a tip end, with the tip end spaced from the hub. The blade is coupled to the hub at the root end such that the blade is rotatable concurrently with the hub and rotation of the blade generates vibrations in the blade. The blade defines a cavity spaced from the tip end. The tunable blade assembly further includes a tunable control assembly which includes a mass adjustable inside of the cavity of the blade to reduce the vibrations in the blade. In certain configurations, a blade assembly is coupled to a hub of a flight vehicle and includes the blade and the tunable control assembly discussed above.
