Abstract
A vane ring damper for a small turbomachine, the vane ring having a plurality of vanes extending between an inner ring and an outer ring and forming a gas flow path, where one of the inner and the outer rings have cuts formed between adjacent vanes to form separate ring segments. In one embodiment, a frictional damper is positioned between the ring segments to provide frictional damping for the vane assembly. in another embodiment, the cuts are formed at about a 45 degree angle and the space is narrow such that adjacent segments rub during vibration and provide the frictional damping for the vane assembly. Inner or outer bands are used to secure the ring segments together and to hold the frictional damper within the space formed between adjacent ring segments. Cuts can be formed between every vane to form a ring segment for each vane, or cuts can be formed in an alternating series such that two or more adjacent vanes extend from a common ring segment.
