摘要： A vane assembly for a gas turbine engine is disclosed having lower thermally induced stresses resulting in improved component durability. The stresses in the vane assembly airfoils are lowered by increasing the flexibility of the vane platform and reducing its resistance to thermal deflection. This is accomplished by placing an opening along the innermost vane assembly rail that reduces the effective stiffness of the platform, thereby lowering the operating stresses in the airfoils of the vane assembly. A removable seal is then placed in the opening in order to prevent undesired leakages, while maintaining the benefit of the increased platform flexibility.

摘要： A compressor component having an airfoil with a profile in accordance with Table 1 is disclosed. The compressor component, such as a compressor blade, has an increased thickness over a portion of the airfoil span in order to increase stiffness. Furthermore, the airfoil has been restacked so as to induce a compressive stress in the blade root/attachment area. The increased stiffness and restacked airfoil combine to improve high-cycle fatigue capability of the compressor component.

摘要： The present invention relates to increasing longevity of the nitrogen content of soil through improved liquid delivery formulations of nitrification inhibitors. The liquid formulation can also be comprised of nitrification inhibitors and optionally urease inhibitors that are blended solutions of each. The nitrification inhibitors are present in a mixture that comprises both a protic and an aprotic solvent system. The novel formulations are designed to be applied to fertilizers, especially urea and manure based fertilizers. The delivery formulations provide an environmentally sound and inherently safe solvating system that improves the storage stability of the urease inhibitors by utilizing liquid organic non-water containing solvents, maintains the nitrification inhibitors in solution to storage temperatures of at least 10° C., and provides improved application to fertilizer of nitrification inhibitors. These delivery formulations enable safe storage, transport and subsequent application or blending with urea-based or manure-based fertilizers that can be applied to soil in either a liquid or granular form to provide improved nitrogen retention in the soil for uptake for plant life.
