  • Method and apparatus for determining lubricant contamination or deterioration in an engine
    Patent number: 10704734
    Abstract: An apparatus and method for determining lubrication contamination or deterioration in an engine or a lubricant system of an engine can include at least one sensor provided in the lubricant system. The sensor can sense an aroma of a lubricant or the air around the lubricant to measure a chemical composition or an aromatic. The sensed chemical composition or aromatic can be compared to a baseline or threshold to determine a particular contamination type or deterioration level of the lubricant.

  • BLADE CONTAINMENT STRUCTURE
    Publication number: 20200011203
    Abstract: A blade containment structure surrounding a fan in a turbofan engine is disclosed. The blade containment structure includes a cellular material to absorb energy and contain fragments of a blade thrown outward; an inner shell; a ductile back sheet spaced radially outward from the inner shell, the ductile back sheet and inner shell cooperating to define a nesting area for the cellular material, wherein the cellular material is bound at its radially inner surface by the inner shell and at its outer surface by the ductile back sheet; and a containment blanket overlaid on the ductile back sheet, the containment blanket being of the type effective to contain fragments of the blade that penetrate through the ductile back sheet.
