Abstract: PROBLEM TO BE SOLVED: To provide an article made of a silicon substrate and a barrier layer which inhibits generation of gaseous chemical species of silicon by preventing water from penetrating a silicon surface, and from oxidation of the surface, when the article is exposed to an aquatic environment of high temperatures. SOLUTION: The barrier layer for the silicon substrate includes an aluminosilicate of alkaline-earth metals and an additive which can react with silica to prevent a reaction of the free silica with the barrier layer.

Abstract: The power plant operating method is for a plant of the active clearance controlled type, including a gas turbine engine housed within a nacelle compartment and a cooling air manifold extending around the engine. The method involves admitting active clearance control cooling air into the nacelle compartment and discharging the air against the engine. The method also comprises maintaining the air pressure within the nacelle compartment at altitude cruise conditions at a level which is on the order of one or two and one-half pounds per square inch above the pressure of the air externally of the power plant. The method then involves discharging air from the compartment in an aft direction relative to the aircraft on which the power plant is installed.

Abstract: Chemical vapor deposition (CVD) techniques for forming tough silicon carbide (SiC) matrix composites. The introduction of methyldichlorosilane (MDS) to a reactor containing a fiber preform which been flushed with a noble gas, causes the formation of a carbon layer around the fibers. The carbon interlayer improves the fracture toughness of the composite.
