In the event of ballistic impact, it reacts instantly. Thanks to its self-sealing technology, it seals any puncture caused by projectiles up to <strong>7.62 mm<\/strong>.

In the event of ballistic impact, it responds immediately. Thanks to its self-sealing technology, it blocks any perforation caused by projectiles up to <strong>7.62 mm<\/strong>. This <strong>prevents fuel leakage<\/strong>, <strong>reducing the risk of fire<\/strong>,<strong> explosion<\/strong>, or <strong>loss of the aircraft<\/strong>.<\/p>\n<h4 data-start=\"720\" data-end=\"782\"><strong>A concrete response to military aviation challenges<\/strong><\/h4>\n<p data-start=\"553\" data-end=\"810\">In operational contexts, aircraft are constantly exposed to <strong>threats<\/strong>. In particular, takeoff, approach, and ground support phases carry <strong>high risks<\/strong>. For this reason, the Pronal self-sealing block has been developed as an <strong>immediate passive protection solution<\/strong>.<\/p>\n<p data-start=\"812\" data-end=\"1045\">Furthermore, its<strong> lightweight<\/strong> and <strong>compact<\/strong> design allows for easy integration into unused internal areas. It complies with <strong>international military standards<\/strong> and requires <strong>no modification to the original aircraft structure<\/strong> or fuel system.<\/p>\n<h4 data-start=\"1320\" data-end=\"1370\"><strong>An effective, field-adapted technology<\/strong><\/h4>\n<p data-start=\"1096\" data-end=\"1420\">Made from <strong>nitrile \/ NPVC<\/strong>, the self-sealing block uses polymer materials that can <strong>instantly reseal<\/strong> upon perforation. Unlike other systems, the self-sealing block is installed without contact with rivets, ribs, or internal tank components. As a result, it <strong>perfectly adapts<\/strong> to existing structures, whether in wings or fuselage.<\/p>\n<p data-start=\"1422\" data-end=\"1598\">Moreover, its design enables <strong>quick installation<\/strong> and <strong>simplified maintenance<\/strong>. By reducing risk without compromising aircraft performance, it is a <strong>strategic choice<\/strong> <strong>for <a href=\"https:\/\/www.entreprises.gouv.fr\/secteurs-dactivite\/industrie\/les-comites-strategiques-de-filiere\/la-filiere-aeronautique\">air forces<\/a>.<\/strong><\/p>\n<h4 data-start=\"1995\" data-end=\"2041\"><strong>A key asset in high-risk zones<\/strong><\/h4>\n<p data-start=\"2043\" data-end=\"2294\">In conclusion, the Pronal self-sealing block offers enhanced safety while remaining <strong>easy to integrate<\/strong>.
