    Abstract: A multi-plane annular brush seal includes a front plate, a back plate, and a plurality of bristles. Each of the plurality of bristles has a first lengthwise portion extending from the base end, a second lengthwise portion, and a third lengthwise portion. The front plate and back plate are configured to maintain the bristle first lengthwise portions substantially parallel to a first plane, the second lengthwise portion of the bristles through a transition region, and the bristle third lengthwise portions substantially parallel to a second plane. The first plane is skewed from the second plane by an obtuse angle. At least some of the bristle second lengthwise portions are maintained in contact with the front plate through the transition region and at least some of the bristle second lengthwise portions are maintained in contact with the back plate through the transition region.

    Abstract: An assembly for a gas turbine engine according to an example of the present disclosure includes, among other things, a seal arc segment that has a sealing portion and a pair of opposed rails extending outwardly from the sealing portion. The sealing portion includes a sealing face dimensioned to bound a core flow path and has a backside face opposed to the sealing face. The backside face includes a first localized region, a second localized region between the pair of rails, and a third localized region. A support includes a mounting portion and a first interface portion. At least one retention pin is dimensioned to engage the first interface portion of the support and at least one of the pair of rails such that the seal arc segment is carried by the at least one retention pin. A support plate is arranged relative to the support such that the at least one retention pin is trapped between the support plate and the support. A cooling cavity is established between the support, the support plate, and the second localized region. A method of sealing is also disclosed.
