Abstract: A scupper suitable for a bearing compartment of a gas turbine engine includes a windage blocker in a gutter section upstream of a drain hole, the windage blocker extends from a wall of the gutter section. A method for capturing wept oil in a bearing compartment of a gas turbine engine includes positioning a windage blocker adjacent to a drain hole forming a passage space and increasing a pressure upstream of the windage blocker to generate a vortex downstream of the windage blocker creating an oil re-circulation zone promoting oil drainage into the drain hole.

Abstract: Provided is a food composition which include a myceliated high-protein food product and methods to make such compositions, which are mixtures of myceliated high-protein food products and other edible materials. A food composition includes dairy alternative products, ready to mix beverages and beverage bases; extruded and extruded/puffed products; sheeted baked goods; meat analogs and extenders; baked goods and baking mixes; granola; and soups/soup bases. Food compositions also include texturized plant protein which can be used for making meat-structured plant protein meat analog or meat extender products. The food compositions have reduced undesirable flavors and reduced undesirable aromas due to use of myceliated high-protein food products as compared to use of similar high-protein material that is not myceliated.
