Abstract: Fuel tank inerting systems for aircraft are provided. The systems include a fuel tank, a catalytic reactor arranged to receive a first reactant from a first reactant source and a second reactant from a second reactant source to generate an inert gas that is supplied to the fuel tank to fill an ullage space of the fuel tank, a heat exchanger arranged between the catalytic reactor and the fuel tank and configured to at least one of cool and condense an output from the catalytic reactor to separate out the inert gas, and a controller configured to perform a light-off operation of the catalytic reactor by controlling at least one light-off parameter and, after light-off occurs, adjusting the at least one light-off parameter to an operating level, wherein the at least one light-off parameter comprises a space velocity through the catalytic reactor.

Abstract: A method of adhering a first component to a second component includes priming the first component with an adhesive bond primer containing a primer material, a corrosion inhibitor, and a chemical additive (such as a dye compound), and using an adhesive to attach the second component to the first component through the adhesive bond primer applied on the surface of the second component. The chemical additive allows inspection of the adhesive bond primer with a corresponding radiation source.

Abstract: A fuel tank inerting system is disclosed. The system includes a fuel tank and a catalytic reactor with an inlet, an outlet, a reactive flow path between the inlet and the outlet, and a catalyst on the reactive flow path. The catalytic reactor is arranged to receive fuel from a fuel flow path in operative communication with the fuel tank and oxygen from an oxygen source, and to catalytically react a mixture of the fuel and oxygen along the reactive flow path to generate an inert gas. An inert gas flow path provides inert gas from the catalytic reactor to the fuel tank. An adsorbent is disposed along the fuel flow path or along the reactive flow path.

Abstract: Fuel tank inerting systems are provided. The systems include a fuel tank, an air source arranged to supply air into a reactive flow path, a catalytic reactor having a plurality of sub-reactors along the flow path, and a heat exchanger. The sub-reactors are arranged relative to the heat exchanger such that the flow path passes through at least a portion of the heat exchanger between two sub-reactors along the flow path. At least one fuel injector is arranged relative to at least one sub-reactor. The fuel injector is configured to inject fuel into the flow path at at least one of upstream of and in the respective at least one sub-reactor to generate a fuel-air mixture. A fuel tank ullage supply line fluidly connects the flow path to the fuel tank to supply an inert gas to a ullage of the fuel tank.

Abstract: An aircraft system includes a thermal load, a controller, a tank for storing a cooling liquid, and a supply system for moving the cooling liquid outwardly of the tank and through a control valve to the thermal load. A controller is programmed to control the supply system. A conduit downstream of the thermal load is configured to communicate the cooling liquid to a fuel metering unit. The fuel metering unit also receives fuel from a high pressure pump. The fuel metering unit is configured to deliver a mixture of the cooling liquid and the fuel into a combustor on an associated aircraft engine. The controller programmed to determine a percentage solubility of the cooling fluid into the fuel at a detected temperature and pressure of the fuel reaching the fuel metering unit. The cooling fluid is combustible and soluble in the fuel. An aircraft and a method are also disclosed.

Abstract: A method for providing inert gas to a protected space. The method includes: providing air having a pressure greater than or equal to 2 atmospheres absolute pressure to a chemical inert gas generator; producing an inert gas in the chemical inert gas generator; providing the inert gas to a condenser at an elevated pressure; reducing the water content of the inert gas in the condenser; and providing the dried inert gas to a protected space.

Abstract: A method of applying a trivalent chromium or chromium-free conversion coating to a metallic substrate including mixing a dye compound that interacts with electromagnetic radiation outside the human visual spectrum but not electromagnetic radiation that is within the human visual spectrum to produce an observable emission into the trivalent chromium or chromium-free conversion coating mixture to allow for inspection of the coating after applied with a correlating electromagnetic radiation source.

Abstract: A fuel tank inerting system includes a primary catalytic reactor comprising an inlet, an outlet, a reactive flow path between the inlet and the outlet, and a catalyst on the reactive flow path. The catalytic reactor is arranged to receive fuel from the fuel tank and air from an air source that are mixed to form a combined flow, and to react the combined flow along the reactive flow path to generate an inert gas. The system also includes an input sensor that measures a property of the combined flow before it enters the primary catalytic reactor and an output sensor that measures the property of the combined flow after it exits the primary catalytic reactor.
