Abstract: The invention is a method for controlling blade tip clearance in a turbine engine having a flowpath extending therethrough, and a system for carrying out the method. The method includes acquiring a first nonpulsating pressure signal Pc representative of tip clearance, sensing a second pressure PB substantially unaffected by tip clearance, forming an actual ratio of the acquired pressure and the sensed pressure, determining an error E having an actual component and a desired component, the actual component being a function of the actual ratio; and commanding a clearance control system to reduce the error.

Abstract: A stator assembly (16) for a rotary machine (10) having an array of wall segments (48) for bounding a working medium flow path is disclosed. Various construction details which provide a sealing structure for the segments are developed. In one detailed embodiment, a removable seal retainer (42) for a seal chamber (98) bounded by wall segments traps a resilient seal member (44) in the seal chamber. In one particular embodiment, a modular subassembly (172) for the engine is an outer air assembly disposed in a fixture (174) as the subassembly is assembled.
