Abstract: A minimum creep life location (MCLL) on a blade for a turbine blade design is received. A temperature at the MCLL on the blade is monitored. When the temperature at the MCLL exceeds a predetermined threshold, a cooling air supply is adjusted to lower the temperature below the threshold during engine operation.

Abstract: A turbofan engine includes a fan, a core turbine engine, and a thermal management system. The thermal management system has a thermal transport bus along which a working fluid is movable, one or more heat-source heat exchangers positioned along the thermal transport bus, and one or more heat-sink heat exchangers arranged in fluid communication with the one or more heat-source heat exchangers via the thermal transport bus. The thermal transport bus has a thermal transport bus capacity determined by multiplying a propulsive effectiveness factor associated with the turbofan engine by a heat load factor associated with the thermal transport bus. The thermal transport bus capacity is between 0.07 and 33.65 for an overall inlet temperature of the working fluid at an overall inlet of the one or more heat-source heat exchangers being between 31 and 200 degrees Celsius and the propulsive effectiveness factor being between 0.52 and 1.37.

Abstract: A gas turbine engine is provided having: a turbomachine; a fan section having a fan rotatable by the turbomachine; a nacelle enclosing the fan; and an engine controller positioned within the nacelle. The nacelle defines an inner surface radius (r) along the radial direction inward of the engine controller, wherein the engine controller defines a radial height (?r) along the radial direction, a total volume (V), and a normalized radius (r?). The normalized radius (r?) is a ratio of the inner surface radius (r) to the total volume (V) to cube root, and wherein these parameters are related by the following equation: 0.1 r ? ? 1 < ? r r < K r ? ? 4 / 3 . wherein the normalized radius (r?) is between 1.25 and 8 and K is equal to 40%, or the normalized radius (r?) is between 2.75 and 4.5 and K is equal to 65%.

Abstract: An orifice assembly includes a first member defining an orifice having a first dimension in a compressed state and a thermally-sensitive material arranged adjacent to the first member. The thermally-sensitive material has a rigid, first state that applies force to the first member so as to maintain the first dimension of the orifice in the compressed state and a flexible, second state configured to release the force applied to the first member. As such, when subjected to temperatures above a predetermined temperature threshold, the thermally-sensitive material changes from the rigid, first state to the flexible, second state to allow the first dimension of the first member in the compressed state to passively expand to a decompressed, second dimension, the second dimension being larger than the first dimension.

Abstract: A turbofan engine includes a fan, a core turbine engine having one or more turbines and an exhaust section, and a hydrogen-exhaust gas heat exchanger in flow communication with the exhaust section and hydrogen flowing along a hydrogen supply line. The hydrogen-exhaust gas heat exchanger defines a load capacity factor determined by raising a product to a one-quarter power, the product being determined by multiplying a heat transfer surface area density associated with the hydrogen-exhaust gas heat exchanger by a process conductance parameter that relates characteristics of hydrogen, ambient air, and exhaust gas at takeoff, as well as a fan diameter of the fan and a number of turbine stages of the turbofan engine. The load capacity factor is between 4.37 and 28.65 for the fan diameter being between 0.5 and 3.5 meters and the heat transfer surface area density being between 500 m2/m3 and 10,000 m2/m3.

Abstract: A method for improving the fire resistance of a cellulose material comprises mixing boric acid with methanol to form a boric acid ester, combining the borate ester with magnesium sulfate to form a low viscosity magnesium borate sulfate solution, treating the cellulose material with the magnesium borate sulfate solution, and heating the treated cellulose material to evaporate remaining alcohol and solvent to form a crystals of a complex mixture containing combinations of magnesium sulfate, boric acid, magnesium borate, magnesium borate sulfate and their hydrates.

Abstract: A method for improving the hydrophobic properties of a cellulosic material having a measurable moisture content without leaving an acidic residue comprises immersing the material in an inert gas, treating the material at a first temperature of between about 180° F. and about 250° F. with a vapor of silane until the silane reacts with the moisture to form hydroxysilanes and an acid vapor, then treating the material at a second temperature of between about 280° F. and about 350° F. until the hydroxysilanes convert to dehydrated silanes that are diffusely resident in the material, and removing the moisture, the acid vapor and remaining silane vapor until the treated material is substantially acid free.

Abstract: Techniques and a graphical user interface for abstracting a request from a development environment to an object model of an object store are disclosed herein. A request for data is made by the development environment, and the request is abstracted to make in compatible with the object model (e.g., by negating properties related to bitness, versioning, etc.). The request is transmitted to a broker process that retrieves a method and/or data commands corresponding to the request. The broker process may also decode one or more method parameters of the request. If one or more method parameters are not compatible with the object model, an adapter may be loaded into the object model to make the object model compatible with the request. The broker process may also transmit the method, data commands, and/or request to the object model wherein the request is fulfilled by the object model.

Abstract: Synthesis of a support material impregnated with silver sulfide provides a sorbent composition. Generating the silver sulfide relies on reaction of sulfur dioxide and one of hydrogen gas and hydrogen sulfide in presence of the support material following silver loading of the support material. Contacting a fluid stream with the sorbent composition removes heavy metal from the fluid stream.

Abstract: A data file comprising a plurality of blocks of data may have two or more versions. The meaning of the data file is insensitive to the ordering of the blocks of data within the data file. Updates to the data file may be identified by providing each of said plurality of blocks of data with a first checksum and each of said versions of the data file with a second checksum of the said version of the data file as a whole. The second checksum of the first version of the data file is compared with the second checksum of the second version of the data file. If the comparison indicates that the second checksums of the first and second versions of the data file differ, then the first checksums of each of said plurality of blocks of data of the first and second versions of the data file are compared and an indication is provided of which of the plurality of blocks of data differs between the first and second versions of the data file.

Abstract: Dynamic collaborative project extensibility is provided via composition containers in a managed extensibility framework within an integrated development environment. A browser-based collaborative environment project is extended, using an extension artifact factory to obtain extension artifacts within composition containers. A class library project can be configured with a custom action, a browser-based collaborative environment project extension artifact can be created representing the custom action, and a factory class for the project extension artifact can then be created with an export attribute for discovery within a composition container.
