    摘要： A process of depositing a coating system suitable for use as an environmental barrier coating on various substrate materials, particularly those containing silicon and intended for high temperature applications such as the hostile thermal environment of a gas turbine engine. The process comprises depositing a first coating layer containing mullite, and preferably a second coating layer of an alkaline earth aluminosilicate, such as barium-strontium-aluminosilicate (BSAS), by thermal spraying while maintaining the substrate at a temperature of 800° C. or less, preferably 500° C. or less, by which a substantially crack-free coating system is produced with desirable mechanical integrity.

    摘要： Improved adhesion of thermal barrier coating systems to nonmetallic substrates using a layer of silica on an underlying nonmetallic substrate that includes a silicon containing material is described. The improved adhesion occurs because the improved thermal barrier system improves the temperature capability of the system by providing a layer adjacent the substrate that has improved thermal performance and that is not subject to deterioration. The application of a silica layer of predetermined thickness adjacent the substrate also forms a diffusion barrier for oxygen while eliminating the need to transform an external layer of the substrate by a pre-oxidation step. This diffusion barrier prevents any oxidizable component of the substrate from decomposing. The thermal/environmental barrier coating (T/EBC) system includes an intermediate layer containing YSZ and BSAS, mullite and/or alumina, which is preferably used in combination with a mullite layer that overlies the surface of the silica layer, a layer of BSAS between the mullite layer and the intermediate layer, and a thermal barrier coating of YSZ overlying the intermediate layer.

    摘要： A binary memory image in system is modified. The system may or may not already have virtual memory management enabled. Virtual memory management is enabled and/or modified by inserting a sub-OS virtual memory management layer in the binary memory image. Part of the binary memory image may be compressed to make room for the sub-OS virtual memory management layer.

    摘要： A fuel injector for a turbine engine may include a body member disposed about a longitudinal axis, and a barrel member located radially outwardly from the body member. The fuel injector may also include an annular passageway extending between the body member and the barrel member from a first end to a second end. The first end may be configured to be fluidly coupled to a compressor of the turbine engine and the second end may be configured to be fluidly coupled to a combustor of the turbine engine. The fuel injector may also include a perforated plate positioned proximate the first end of the passageway. The perforated plate may be configured to direct compressed air into the annular passageway with a first pressure drop. The fuel injector may also include at least one fuel discharge orifice positioned downstream of the perforated plate. The at least one fuel discharge orifice may be configured to discharge a fuel into the annular passageway with a second pressure drop. The second pressure drop may have a value between about the first pressure drop and about 1.75 times the first pressure drop.

    摘要： A fuel injector for a gas turbine engine is disclosed. The fuel injector includes an injector housing having a longitudinal axis. The injector housing includes one or more fuel galleries annularly disposed about the longitudinal axis, and a compressed air inlet. The fuel injector also includes a premix barrel having a proximal end and a distal end circumferentially disposed about the longitudinal axis. The premix barrel is fluidly coupled to the fuel galleries and the compressed air inlet at the proximal end and is configured to couple to a combustor of the gas turbine engine at the distal end. The fuel injector also includes a substantially cylindrical pilot assembly disposed radially inwards of the premix barrel having a first end and a second end. The second end is coupled to the injector housing and the first end is located proximate the distal end of the premix barrel. The fuel injector further includes a pilot liquid tube having a third end and a fourth end disposed radially inwards of the pilot assembly. The fourth end is removably coupled to the injector housing and the third end is located proximate the first end of the pilot assembly.
