BOAS HAVING RADIALLY EXTENDED PROTRUSIONS

A blade outer air seal (120) may comprise an arcuate segment (250). The arcuate segment (250) may comprise an aft wall (258) having a first radially extending protrusion (200a) at a circumferential end of the aft wall (258). A first hook (262) may extend aft from the aft wall (258). A first gusset (...

Zusammenfassung:	A blade outer air seal (120) may comprise an arcuate segment (250). The arcuate segment (250) may comprise an aft wall (258) having a first radially extending protrusion (200a) at a circumferential end of the aft wall (258). A first hook (262) may extend aft from the aft wall (258). A first gusset (270a) may extend from the first radially extending protrusion (200a). A radial height of the first radially extending protrusion (200a) may be greater than a radial height of a second radially extending protrusion (200c) of the aft wall (258).
