In aerospace, the use of oxygen and hydrogen is crucial but carries high risks. These two elements, as useful as they are dangerous, require a rigorous approach in terms of safety, design and monitoring of the environments in which they are used. In this article, we take a closer look at the critical issues involved in handling oxygen and hydrogen in aerospace components and how Sensitron helps to ensure maximum protection of people and infrastructure.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Oxygen and hydrogen are key elements in many aerospace applications, from propulsion to life support. However, their use requires careful handling to avoid significant risks:<\/p>\n

Oxygen<\/strong>: Used for life support in space habitats, space suits and combustion propulsion systems. However, at high pressures or in confined environments, it can render materials highly flammable.<\/p>\n

Hydrogen<\/strong>: This is a key propellant, particularly in liquid form in rockets (think of the famous LH2\/LOX mix). Very light and with high energy density, it is however extremely volatile and permeable, with a very high risk of explosion in the event of an undetected leak.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The safe handling of oxygen and hydrogen involves complex technical challenges related to the nature of these gases. Let us take a look at the main critical aspects:<\/p>\n

    \n
  1. \n

    Permeability of Materials<\/strong>
    \nHydrogen can penetrate the molecular structure of many materials, causing brittleness (hydrogen embrittlement) and possible structural failure.<\/p>\n<\/li>\n

  2. \n

    Combustibility High<\/strong>
    \nBoth gases can create highly combustible environments even with small concentrations. A spark or local overheating is enough to trigger violent reactions.<\/p>\n<\/li>\n

  3. \n

    Continuous Monitoring<\/strong>
    \nIn environments such as cabins, cryogenic tanks or combustion chambers, it is essential to detect every minute leak to avoid catastrophic damage.<\/p>\n<\/li>\n<\/ol>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
