Patent ID: 11480055

Abstract:
A modular casing manifold for cooling fluids of a gas turbine engine is presented. The modular casing manifold has an annular shape including an axial inner plate, an axial outer plate, a radial forward plate and a radial aft plate. The forward plate is attached to the inner and outer plates at forward end. At least a portion of the aft plate is attachable to and removable from the inner and outer plates at aft end for enabling cooling fluid to cool turbine blades of the gas turbine engine. The modular casing manifold includes preswirler segments. At least a number of the preswirler segments are attachable to and removable from the forward plate for enabling cooling fluid to cool turbine blades of the gas turbine engine. The modular casing manifold enables alternative cooling fluids to cool turbine blades of the gas turbine engine with minimal cost and assembly flexibility.
