  • Publication number: 20160010199
    Abstract: Processes and systems for forming a coating system on a component. The process of forming the coating system on the component includes placing an apparatus in a location that promotes coating particles in flight to be redirected towards a surface on the component. The surface is obstructed by portions of the component limiting line-of-sight from a source of the coating particles to the surface. The coating particles are then deposited onto the surface of the component. The coating particles initially travel in a direction of initial particle travel and are redirected by the apparatus towards the surface on the component at a direction of final particle travel relative to the surface. The line-of-site from the source of the coating particles is at an angle of less than 30 degrees relative to the surface of the component and the direction of final particle travel is at an angle of 30 degrees or more relative to the surface of the component.

  • Publication number: 20140345254
    Abstract: A third stream duct producing a third air stream at reduced pressure that is exhausted through a separate nozzle that is concentric with the main or primary engine nozzle. The third stream exhaust air from the separate concentric nozzle is exhausted to a location at which pressure is ambient or sub-ambient. The location at which the third stream air is exhausted contributes to the thrust of the aircraft. The airstream from the third air duct is exhausted through an exhaust nozzle of the third duct that is positioned at the interface between the aft of the airframe and the leading edge of the engine outer flaps. This location is a low pressure region that has a recirculation zone. The exhaust of third stream air to this low pressure region substantially reduces or eliminates this recirculation zone and associated boat tail drag, thereby improving the efficiency of the engine.
