Abstract
A tip treatment bar component (16) for positioning within an annular cavity surrounding a fan (4) within a gas turbine engine comprises a longitudinal portion (30) with a platform (32, 34) at each end. The platforms (32, 34) of adjacent bars (16) abut each other laterally to provide a slot (28) between adjacent tip treatment bar components (16). A projection, for example a tang (24, 26), extends from the platforms (32, 34) in a direction away from the longitudinal portion (30) of the tip treatment component (16). This serves to locate the bar component (16) in the engine casing (2).
Claims16
A tip treatment bar component for a gas turbine engine, the bar component comprising:
- a longitudinal portion having opposite ends;
- a platform on at least one end of the longitudinal portion, the platform extending laterally to at least one side of the longitudinal portion.
A tip treatment assembly comprising an annular array of tip treatment bar components, each bar component comprising:
- a longitudinal portion having opposite ends;
- a platform on at least one end of the longitudinal portion, the platform extending laterally to at least one side of the longitudinal portion,
- the platforms of adjacent bar components abutting each other to maintain spacing between the longitudinal portions of the bar components.
In a gas turbine engine, a tip treatment assembly comprising:
- oppositely disposed annular supports, each having an annular channel;
- an annular array of tip treatment bar components extending between the annular supports, each bar component comprising:
- a longitudinal portion having opposite ends;
- a platform on at least one end of the longitudinal portion, the platform extending laterally to at least one side of the longitudinal portion;
- and
- a projecting tang extending from the or each platform in a direction opposite the longitudinal portion
- the platforms of adjacent bar components abutting each other to maintain spacing between the longitudinal portions of the bar components, and the projecting tangs engaging the respective channels in the annular supports.
