Abstract: A combustor for use in a gas turbine engine including a heat shield panel having a first surface and a second surface opposite the first surface of the heat shield panel and a combustor shell having an inner surface and an outer surface opposite the inner surface. The inner surface of the combustor shell and the second surface of the heat shield panel being in a facing spaced relationship defining an impingement cavity therebetween. The combustor shell further includes an impingement aperture that has a nonaxisymmetric shape. The impingement aperture extending from the outer surface to the inner surface through the combustor shell.

Abstract: An in-seat mini-bar assembly, apparatus and method of manufacture is provided. The assembly includes a housing that is insertable into a compartment of the seating module and includes a container with an interior cavity that is conductively cooled by thermo-electric elements of a micro-chiller unit mounted on a conductive rear plate that forms an exterior side of the container. A vent is configured proximate to a front section of the housing to receive outside air forward of the housing for channeling the outside air to a rear section of the housing using a duct attached to the vent at the front section. The duct is shaped for a fluidic intake of the outside air by a frontal flange having a wide cross-sectional area that is gradually tapered to a circular cross-sectional area to direct the airflow in a uniform manner.

Abstract: A transformer bobbin includes a first bobbin member including a first end defining a first opening, a second end defining a second opening, an inner surface defining the first opening and an outer surface. The inner surface includes a first plurality of fins that extend between the first end and the second end. A second bobbin member is disposed about and spaced from the first bobbin member. The second bobbin member includes a first end portion defining a first opening portion, a second end portion, an inner surface portion and an outer surface portion. One of the outer surface of the first bobbin member and the outer surface portion of the second bobbin member includes a second plurality of fins that extend between the first end portion and the second end portion.

Abstract: Disclosed is a heat exchanger comprising a first flow path with an inlet, an outlet and a first surface and a second flow path with an inlet, an outlet and a second surface wherein at least one of the first surface and the second surface has a portion consisting of a shape memory alloy which has a first shape at a first temperature, a second shape at a second temperature different than the first temperature, and returns to the first shape in response to a return to the first temperature.

Abstract: In accordance with at least one aspect of this disclosure, a system includes, an environmental control system (ECS) having a plurality of ducts configured to convey a flow of air into an interior space through the plurality of ducts, a plurality of valves disposed in the plurality of ducts to control the flow of air through a respective duct into the interior space, an overhead bin mounted in the interior space below the plurality of ducts relative to the direction of airflow, and a diffuser disposed at an outlet of the plurality of duct configured to induce the airflow to flow along a convex outer surface of the overhead bin.

Abstract: Drying a planar substrate such as paper sheet goods for packing materials includes layering a phase change material (PCM) on a substrate, in which the substrate has a moisture content and adapted for moisture removal to form a planar medium. A drying process disposes the substrate adjacent to a plurality of rollers and heat the layered substrate to a predetermined temperature based on a specific heat of the PCM. The rollers advance the layered substrate in series through pocket ventilation regions between the heat transfer elements, such that the pocket ventilation regions permit drying of the substrate enhanced by the specific heat of the temperature sensitive material. Upon drying, the layered substrate forms the planar medium suitable for use as a packing medium or other suitable application. The pocket ventilation regions are based on the PCM to facilitate drying and eradication of moisture from the paper planar substrate.
