FULL HOOP BLEED MANIFOLDS FOR LONGITUDINALLY SPLIT COMPRESSOR CASES

摘要

FULL HOOP BLEED MANIFOLDS FOR LONGITUDINALLY SPLIT COMPRESSOR CASES A compressor case structure capable of enhanced active clearance control within the structure is disclosed. Various construction details which enable the discharge of cooling air against the case and which minimize thermal distortion of the case are developed. The concepts are applied to a longitudinally split compressor case and include an external bleed manifold of circular cross section which extends across the longitudinal split in the case. Cooling air is dischargeable beneath the manifold to cool the case structure. EH-6396
