Abstract
A blade outer air seal includes a blade outer air seal body having a radially inward facing web to be centered on a rotational axis of an associated engine. The blade outer air seal has a leading edge and a trailing edge and there is a leading edge mount hook and a trailing edge mount hook. A cooling air inlet in the leading edge mount hook communicates with a source of cooling air. The web is intermediate the leading edge mount hook and the trailing edge mount hook and the cooling air inlet communicating with a cooling air circuit in the web. Air passes from the leading edge toward the trailing edge and then to an outlet extending radially outwardly and into a central chamber defined between the leading edge mount hook and the trailing edge mount hook. The outlet is upstream of the trailing edge mount hook.
