摘要： An apparatus and a method for simulating a mechanical stress applied to a sealant from a lightning strike upon an aircraft is provided. The apparatus comprises a specimen, a test fixture, and a capacitor. The specimen comprises an electrically non-conductive sealant for an aircraft fuel tank having a cylindrical shape, and an electrically conductive wire centered axially within the sealant. The test fixture secures the specimen during testing. The capacitor is electrically coupled to the test fixture, and simulates a lightning strike upon the aircraft by vaporizing the wire with a current to generate a mechanical shock to the sealant.

摘要： Incendivity test systems and methods are disclosed. Incendivity test systems include a non-flammable gas mixture and a test article in a test chamber. The non-flammable gas mixture includes a thermally reactive reagent that is formulated to thermally react to produce a reaction product. Incendivity test systems also include an energy source configured to apply an energy discharge such as a simulated lightning strike to the test article. Incendivity test systems also include a detection device configured to measure an indicator species in the non-flammable gas mixture (e.g., the thermally reactive reagent and/or the reaction product). Incendivity test methods include contacting the test article with the non-flammable gas mixture, applying the energy discharge to the test article, and then measuring the amount of the indicator species and determining the incendivity of the test article in response to the energy discharge based upon the amount of the indicator species.

摘要： Ignition-quenching systems include an ignition-risk structure that extends from a support structure into a combustible environment and include a porous ignition-quenching cover that substantially covers the ignition-risk structure. The ignition-quenching cover is configured to quench an ignition event triggered by an ignition source associated with the ignition-risk structure. Ignition-quenching covers generally include a porous body. The porous body may include one or more porous elements. Methods according to the present disclosure include installing a porous ignition-quenching cover over an ignition-risk structure to prevent bulk combustion, e.g., of a fuel vapor in a fuel tank, due to an ignition event associated with the ignition-risk structure.

摘要： Ignition-quenching covers are configured to quench an ignition event in a combustible environment triggered by an ignition source associated with an ignition-risk structure. Ignition-quenching covers comprise a porous body that includes two or more porous elements and are configured to cover the ignition-risk structure, wherein the ignition-risk structure is associated with a potential ignition source that may produce the ignition event in the combustible environment. The porous body defines passages sized to quench the ignition event. Methods comprise installing a porous ignition-quenching cover over an ignition-risk structure to prevent bulk combustion, e.g., of a fuel vapor in a fuel tank, due to an ignition event associated with the ignition-risk structure.

摘要： Methods of incendivity testing include applying a flexible sheet over a test article to form a sealed space between the flexible sheet and a surface region of the test article. Methods further include filling the sealed space with an indicator gas mixture, applying an energy discharge to the test article, and determining whether the indicator gas mixture in the sealed space reacted in response to the energy discharge. The indicator gas mixture may be flammable and may be formed while filling the sealed space. Incendivity test systems include the test article, the flexible sheet sealed to the test article to form the sealed space, a gas control module configured to fill, flush, purge, and/or sample gas in the sealed space, and an energy source configured to apply the energy discharge to the test article.

摘要： Systems and methods for quantifying combustion arrester performance are disclosed. Methods include filling an upstream volume and a combustion arrester with a flammable gas, igniting the flammable gas in the upstream volume (and upstream of the combustion arrester), measuring a composition of gas discharged from the combustion arrester due to ignition of the flammable gas, and quantifying the performance of the combustion arrester based on the composition of gas measured. The measured gas composition may include types and/or amounts of combustion species within the gas discharged from the combustion arrester.
