Abstract: A system produces inert gas and generates electrical power with an electrochemical cell with an anode and a cathode separated by a proton transfer medium separator. The anode includes an oxygen evolution reaction catalyst and a hydrogen oxidation reaction catalyst, and the system is operated in alternate modes: a first mode in which water is electrolyzed at the anode with an oxygen evolution reaction catalyst to form protons and oxygen, the protons are transported across the separator to the cathode and reacted with oxygen at the cathode, and an inerting gas depleted of oxygen is discharged from the cathode; and a second mode in which protons and electrons are produced from a fuel at the anode with a hydrogen oxidation reaction catalyst, protons are transported across the separator to the cathode, and electrons are transported to the cathode through an electrical circuit to produce electrical power.

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 temperature of the catalytic reactor.

Abstract: An internal recycle reactor for catalytic inerting has a monolithic body having a motive fluid duct, a suction chamber, a mixing region, a reactor section, an outlet, and a recycle passage. The suction chamber includes a suction chamber inlet. The mixing region is configured to receive gaseous fluids from the motive fluid duct and the suction chamber inlet to produce a gaseous mixture. The reactor section includes a catalyst and is configured to receive the gaseous mixture from the mixing region. The outlet is configured to deliver an exhaust gas from the reactor section and the recycle passage is configured to deliver a portion of the exhaust gas to the suction chamber inlet.

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: An inerting system includes a fluid circuit, a reactor within the fluid circuit, at least one particulate removal device (PRD) downstream from the reactor, and a fluid tank. The fluid tank is downstream from the at least one PRD. A method for removing particulates from a fluid stream in a fluid circuit includes receiving a fluid stream in a reactor within a fluid circuit, outputting an exhaust stream from the reactor, receiving the exhaust stream in at least one PRD downstream from the reactor, removing particulate from the exhaust stream, and receiving the exhaust stream with particulate removed in a fluid tank downstream from the at least one PRD.

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.
