Abstract: A turbine shroud segment (64) includes a substrate (66) and a coating layer (72) having varying thickness. Various construction details are developed that provide minimal spalling of the coating layer (72) during use of the shroud segment (64). In a particular embodiment, a shroud segment (64) includes a coating layer (72) that tapers towards the edges. The thickness tapers to a minimum thickness along the leading (74) and trailing edges (76). Within the blade passing region (78) of the shroud segment (64), the coating layer (72) tapers towards the lateral edges to a thickness determined by the minimum thickness required for abrasive contact between the shroud segment (64) and rotor blades (42). In another particular embodiment, the varying thickness of the coating layer (72) is produced by forming the substrate (66) with a concave surface, applying the coating (72), and subsequently machining back the coating layer (72) to the desired dimensions.

Abstract: An embedded optical sensor has a plurality of layers (10-20) and an optical fiber (21) with a fiber grating (28), disposed between the layers (14, 16). The layers (10-20) comprise filaments (22) and resin (24) which have different thermal expansion coefficients and the filaments (22) are oriented so as to create unequal transverse residual stresses that act through the geometry of a resin-rich region that surrounds on the grating (28) in the fiber (21). The unequal transverse residual stresses cause birefringence in the grating (28), thereby causing the grating (28) to reflect light (32) having two wavelengths with a predetermined separation, each along a different polarization axis. The wavelength separation and average wavelength between such separation have different sensitivities to temperature and strain, thereby allowing independent temperature and strain measurements using only a single grating. The birefringence is maximized when the filaments (22) of the adjacent layers (10, 12) are oriented at 90 degrees with respect to the longitudinal (Z-axis) of the fiber (21).

Abstract: A two-step operation passage forming process includes steps to minimize tolerance buildup between the operations. The method includes a step of determining a spatial error between the coordinate systems of the two operations. In a particular embodiment, the step of determining the spatial error includes forming an indexing hole in a template at a particular location using the first operation, aligning the apparatus of the second operation with the indexing hole, and measuring the spatial error between the actual position of the indexing hole and a translated position. The determined spatial error may then be used as an offset in the second operation to account for tolerance differences between the two operations.

Abstract: A process for producing a fine grain forged superalloy article having a high yield strength at intermediate temperatures. A preferred starting composition comprises, by weight, 15 % Cr, 13.6 % Co, 4.1 % Mo, 4.6 % Ti, 2.2 % Al, 0.01 % C, 0.007 % B, 0.07 % Zr, balance Ni. This material is forged at a temperature above the gama prime solvus and at a true strain of at least 0.5. Alternately, the material may be forged below the gamma prime solvus temperature with intermediate super solvus anneals. The overaged material is then worked at a temperature below the gamma prime solvus. The resultant fine grain material is then heat treated or can be further isothermally forged prior to heat treatment to produce complex shapes.

Abstract: Blade attachment slots for gas turbine engines are prepared by grinding to a stepped, generally straight sided configuration, semi-finish grinding to an envelope about 0.005 inches (.013cm) to 0.010 inches (.025cm) above the blueprint configuration, and finishing by broaching. This reduces the overall cost of the manufacturing process, permits a more economical use of existing broach machines, and allows greater versatility for short model runs and "just-in-time" production.

Abstract: Fluid leakage restriction in multi-layered systems that contain fluids such as electrochemical cell devices (12) with sealing surfaces (10) defining patterns of ridges forming concentric rings surrounding through apertures within the surfaces require a new surface design for use of a potential through aperture site. A crossed-ridge sealing surface (10) is comprised of a first plurality of aligned ridges (48) and a second plurality of aligned ridges (50) that crosses the first plurality of aligned ridges to define sealing cells (52) that surround the existing through apertures (28) and potential through aperture sites, so that one sealing surface design may enhance fluid leakage restriction for a variety of actual and potential through apertures.

Abstract: A fuel control system for a gas turbine engine having a staged combustor includes apparatus and methods to operate the combustor during pilot operation, staged operation, and transition between the two modes of operation. Various construction details are developed which provide a fuel control having a switch with built in hysteresis for determining the transition points between operating modes. In one embodiment, the combustor is switched from pilot to staged operation at a thrust level greater than the thrust level at which the combustor is switched from staged to pilot operation. During transitions between operating modes, the changes in fuel flows are limited by a plurality of rate limits to prevent combustor fuel spikes and blow-outs from occuring. During engine starts, the fuel lines to the main combustor are pre-filled to provide responsiveness during the transition from pilot to staged operation.

Abstract: The present invention provides a process and a system for removing inorganic carbon in the form of free and dissolved CO2 from aqueous solutions. The process and the system contemplate the use of a thermally regenerable and optionally thermally sterilizable ion exchange resin for adsorption of inorganic carbon. As a result, the need for regeneration of the resin by chemical means is obviated and expendable resin quantities are reduced. Therefore, the present invention will be especially useful in spacecraft and planet based applications where the need exists for reduced weight and volume water processing systems.
