When launching and flying a rocket, vibrations must be reduced to such an extent that they do not cause damage to the payload and structure. In the “Silent Running” project, MT Aerospace and Fraunhofer LBF are using carbon-fibre-reinforced plastics (CFRP) with metamaterials, in order to reduce the vibrations that affect on the payload and structure during acceleration. Metamaterials combine the benefits of active and passive vibration reduction and are used, in the automotive industry, amongst others. “Silent Running” specifically targets to minimise vibrations in the upper stages of future Ariane carrier rockets. The innovative vibration dampers should be integrated into the load-bearing structure of the carrier rockets, so that the heavy damping elements conventionally used are no longer required.
Wakati wa uzinduzi na kuruka roketi, vibrations lazima kupunguzwa kwa kiasi kwamba wao si kusababisha uharibifu wa mzigo na muundo. Katika mradi wa "Silent Running," MT Aerospace na Fraunhofer LBF wanatumia plastiki iliyoimarishwa na nyuzi za kaboni (CFRP) na metamaterials, ili kupunguza vibrations ambayo huathiri mzigo na muundo wakati wa kuharakisha. Metamaterials kuchanganya faida ya kazi na passive vibration kupunguza na ni kutumika, katika sekta ya magari, miongoni mwa wengine. "Silent Running" hasa inalenga kupunguza vibrations katika hatua za juu ya baadaye Ariane carrier roketi. Vipuli vya vibrating vya ubunifu vinapaswa kuunganishwa katika muundo wa kubeba mzigo wa roketi za kubeba, ili vipengele vikali vya kupumzika vinavyotumiwa kwa kawaida havihitaji tena.
