Abstract: An atomizing spray nozzle device includes an atomizing zone housing that receives different phases of materials used to form a coating. The atomizing zone housing mixes the different phases of the materials into a two-phase mixture of ceramic-liquid droplets in a carrier gas. The device also includes a plenum housing fluidly coupled with the atomizing housing and extending from the atomizing housing to a delivery end. The plenum housing includes an interior plenum that receives the two-phase mixture of ceramic-liquid droplets in the carrier gas from the atomizing zone housing. The device also includes one or more delivery nozzles fluidly coupled with the plenum chamber. The delivery nozzles provide outlets from which the two-phase mixture of ceramic-liquid droplets in the carrier gas is delivered onto one or more surfaces of a target object as the coating on the target object.

Abstract: A particle separator includes a separator body in a primary fluid passageway of a machine. The primary fluid passageway includes one or more bleed holes through which a diverted portion of the fluid flowing in the primary fluid passageway toward a volume of the machine is diverted into an auxiliary flow passageway that bypasses the volume and directs the diverted portion of the fluid toward one or more other components of the machine. The separator body is coupled with the inner wall and/or outer wall of the primary fluid passageway. The separator body includes an upstream edge positioned to separate at least some particles carried by the fluid from the fluid as the diverted portion of the fluid bends around and flows over the at least one upstream edge of the separator body and into the auxiliary flow passageway.

Abstract: A reactive phase spray formulation coating is configured to be disposed on the thermal barrier coating of an article. The reactive phase spray formulation coating comprises a base material and a binder material. The base material has a compliance that is higher than a compliance of the binder material, the binder material has a cohesive strength that is greater than a cohesive strength of the base material, the binder material has an adhesive strength that is greater than an adhesive strength of the base material, and the binder material has a surface area of at least ten square-meters per gram that is greater than a surface area of the base material. The binder material is configured to improve a cohesive strength level, an adhesive strength level, and a compliance of the formulation coating of the thermal barrier coating relative to the formulation coating not including the binder material.

Abstract: A control system having one or more controllers configured to determine a maintenance date of an engine based on monitored parameters of the engine of an aircraft. The one or more controllers also are configured to, determine an amount of coating sprayed on the engine on the determined maintenance date based on the monitored parameters and determined maintenance date. The one or more controllers also are configured to adjust the maintenance date based on needs of an aircraft fleet and regularly scheduled maintenance of the engine.

Abstract: An atomizing spray device includes a housing having plural inlets and one or more outlets fluidly coupled with each other by an interior chamber. The inlets include a first inlet shaped to receive a first fluid and a second inlet shaped to receive a slurry of ceramic particles and a second fluid. The interior chamber in the housing is shaped to mix the first fluid received via the first inlet with the slurry received via the second inlet inside the housing to form a mixture in a location between the inlets and the one or more outlets. The interior chamber in the housing also is shaped to direct the mixture formed inside the housing as droplets outside of the housing via the one or more outlets such that, based on a discharged amount of the first fluid in the droplets, the first fluid promotes evaporation of the second fluid as the droplets traverse from the housing toward a surface of a component.

Abstract: A coating system includes a support fixture sized to be partially inserted into one or more openings of a component and a spray nozzle segment device comprising a housing configured to receive a slurry. The device is disposed radially outward of a central axis of the component and is shaped to extend circumferentially about at least part of the central axis of the component. The housing comprises plural delivery nozzles configured to spray the slurry onto a surface of the component. The device is operably coupled with the support fixture such that the fixture maintains a position of the device within the component when the support fixture is partially inserted into one or more openings of the component.
