Compressed air plenum for a gas turbine engine

摘要

A compressed air supply system for routing compressed air from a compressor to at least one combustor of a gas turbine engine is disclosed. The compressed air supply system may be formed from one or more plenums having an upstream end in fluid communication with an inner chamber of the compressor in which air is compressed and having a downstream end in fluid communication with the at least one combustor. Channeling compressed air through the plenum reduces damage to other components by confining the compressed air within the plenum. An upstream end of the plenum may be sealed to at least a portion of the compressor, and a downstream end of the plenum may be sealed to at least a portion of one or more combustors.

1. A compressed air supply system for routing compressed air from a compressor to at least one combustor of a gas turbine engine, comprising:
a plurality of plenums, each plenum having an upstream end in fluid communication with an inner chamber of the compressor in which air is compressed and having a downstream end in fluid communication with the at least one combustor; wherein the plurality of plenums comprises a plurality of plenums meshed together such that mouths at the upstream end of the plenums form a continuous ring radially outward from compressor blades; wherein each of the plenums extend downstream from the mouth generally tangential to a flow path of an outermost point on a compressor blade and extends axially, wherein the plenum curves radially outward such that the plenum extends generally radially outward; and a flow conditioner at a downstream end of the at least one plenum that is formed from a cylindrical exhaust opening surrounded by the at least one plenum that is larger than a diameter of the cylindrical exhaust opening.
