초록 ▼

A support structure for an outer air seal of a gas turbine engine is disclosed. Various construction details which improve the sealing effectiveness of the outer air seal are developed. The outer air seal is held in close proximity to the rotor blades by the circumferentially adjacent support segmen

대표청구항 ▼

In a gas turbine engine of the type having a segmented outer air seal circumscribing the tips of a row of rotor blades and having a coolable engine case that includes a plurality of external rails extending circumferentially thereabout, the improvement which comprises: a means for attaching the outer air seal to the engine case which includes, a plurality of arcuate upstream support segments each having a central portion and two end portions and each upstream support segment engaging the upstream end of at least one seal segment, a means for attaching each of the upstream support segments to the engine case which affixes only the central portion of the upstream support segment to the engine case with the end portions being free to move circumferentially with respect to the engine case; a plurality of arcuate downstream support segments each having a central portion and two end portions and each downstream support segment engaging the downstream end of at least one seal segment; and a means for attaching each of the downstream support segments to the engine case which affixes only the central portion of the downstream support segment to the engine case with the end portions being free to move circumferentially with respect to the engine case.
