Abstract: PROBLEM TO BE SOLVED: To obtain an improved polyurethane compound usable as an embedding resin for a fan outlet guide vane assembly of a commercial gas turbine engine. SOLUTION: A polyurethane compound suitable for this invention is obtained by mixing a polyurethane prepolymer preparation with an aromatic amine curing agent in the ratio of about 0.9: about 1 to 1:1, preferably about 0.95:1 to about 1:1. The polyurethane prepolymer preparation related to this invention comprises a blend mixture obtained by blending different polyethers composed of diphenylmethane diisocyanate (MDI) as a base and the amine curing agent is a blended mixture of an oligomeric diamine and an aromatic diamine containing a catalytic component. These blend mixtures are both liquid at a room temperature.

Abstract: PROBLEM TO BE SOLVED: To prevent heat deterioration by using a coating material on a compressor part of a turbine part. SOLUTION: Seawater is made to remain as hemispherical droplets rather than forming a water film as it spreads on a blade in the case when seawater remains by restraining wetting by sea water on the blade by increasing a contact angle at more than about 50 deg. by covering a thin coating material capable of extremely preventing wetting by seawater and having an adhesive property on a metal member of a compressor part including the blade and a vane. Consequently, it is possible to reduce seawater remaining on a blade surface and to reduce formation and accumulation of salt on a constitutional member of the compressor part. Accordingly, crystal salt never concentrates on the blade of the turbine part and the droplets pass through the inside of a gas turbine engine as they are droplets.

Abstract: A compressor coating is described which can reduce corrosion in the turbine system of a gas turbine engine. The coating is essentially not wet by droplets or aerosols of sea water or other corrodants. The coating reduces the build up of salt deposits on compressor components and their subsequent passage into the turbine section, thereby preventing severe localized corrosion which would otherwise occur.

Abstract: Embodiments are directed to obtaining a specification comprising at least one requirement associated with a heating, ventilation, and air-conditioning (HVAC) system, and based on the specification, configuring a control system to control a movement of fluid back and forth across at least one regenerator device of the HVAC system and a mixing of the fluid with ambient air.
