Heat shield for gas turbine has several segments held by clamp segments of which each one holds several heat shield segments to eliminate leakage gaps

摘要

The heat shield (10) which encloses a ring of vanes comprises several identical heat shield segments (12-15) set circumferentially in succession and fixed on a support by clamp segments (16-18) which each hold several of the segments simultaneously. The division between the clamp segments is circumferentially off-set relative to the division between the heat shield segments., preferably by half the length of a heat shield segment.
