ABSTRACT:
A housing for a turbojet engine compressor is disclosed having inner and outer housing portions which may radially expand or contract as the compressor rotor wheel blades expand or contract, so as to maintain a minimum clearance between the housing and the rotor blade tips. A heat transfer manifold is applied about the outer periphery of the outer housing portion to rapidly expand the housing during transient operating conditions of the engine.
