INTERLOCKING COMBUSTOR HEAT SHIELD PANELS

摘要

A combustor heat shield assembly comprises a circumferential array of heat shield panels individually mounted to an inner surface of a combustor shell. Each heat shield panel has a sealing rail extending from a back side thereof and a plurality of bolted connections securely holding the heat shield panel on the combustor shell with the sealing rail in sealing contact with the inner surface of the combustor shell. Each pair of adjacent heat shield panels comprises first and second panels having adjoining lateral edges, the first panel having a boltless area on its back side at a location adjacent to its adjoining lateral edge. The second panel has a first one of its bolted connections provided adjacent to its adjoining lateral edge and in facing relationship with the boltless area of the first panel. A tab projects from the lateral edge of the second panel in overlapping relationship with at least a portion of the boltless area of the first panel for transferring a force from the first bolted connection of the second panel to the boltless area of the first panel.
