ABSTRACT:
An apparatus is provided to thermally control a section of engine casing by flowing heat transfer fluid within an axially disposed set of circular flowpaths within a section of engine casing or flange such as a thermal control ring. Flowpaths are preferably arranged in alternating counterflowing directions in the ring such that there is substantially no circumferential gradient in the mass flowrate weighted average temperature of the heat transfer fluid supplied by any two adjacent counterflowing fluid flowpaths. Each flowpath may have two or more circuits having inlets and outlets for flowing the heat transfer fluid.
