Abstract
A compressor bleed air manifold includes annular outer flanges on opposite sides of the generally annular manifold plenum. The outer and inner flange geometries may be circumferentially tailored to produce optimal case stiffness and thermal response for blade-to-case clearances. The inner flanges are secured to one another by an inner bolt circle radially adjacent the flow path thereby improving the case stiffness, out of roundness and eliminating unsupported sections of the flowpath along an outer diameter thereof. The flanges of the outer bolt circle seal the plenum. The compressor bleed air manifold and the compressor casing load path are thereby isolated from one another.
