Claim 11:
12. A gas turbine engine comprising:
a section including an array of blades rotatable about a longitudinal axis, an array of vanes adjacent to the array of blades, and an array of blade outer air seals arranged circumferentially about the array of blades relative to the longitudinal axis;
a seal assembly dimensioned to span between the array of vanes and the array of blade outer air seals, the seal assembly comprising:
a first side plate, a second side plate and a backing plate that extend circumferentially about the longitudinal axis;
a first brush seal between the first side plate and the backing plate;
a second brush seal between the second side plate and the backing plate;
wherein the first and second brush seals are spaced apart from each other by the backing plate;
wherein the first brush seal is dimensioned to establish a first sealing relationship with the array of vanes, the second brush seal is dimensioned to establish a second sealing relationship with the array of blade outer air seals; and
wherein the first brush seal is dimensioned to extend in a first axial direction from the backing plate relative to the longitudinal axis such that the first sealing relationship is established along an axial face associated with the array of vanes, and wherein the second brush seal is dimensioned to extend in a second axial direction from the backing plate relative to the longitudinal axis such that the second sealing relationship is established along an axial face associated with the array of blade outer air seals.
