Представлен концепт всасывающего огнетушителя для космических кораблей и подлодок

Одно из самых самых страшных происшествий, которые могут случиться в космическом корабле или подлодке — это пожар. Из-за замкнутости пространства, в них невозможно использовать обычные огнетушители, поэтому экипаж вынужден пользоваться углекислотными аналогами. Перед их использованием необходимо надевать защитную маску, что отнимает много времени — за этот промежуток огонь может нанести большой ущерб. В надежде исправить эту проблему, исследователи из японского Технологического университета Тоёхаси представили прототип безопасного огнетушителя, который работает совершенно по другому принципу.

Вместо того, чтобы тушить огонь при помощи пены или диоксида углерода, новый огнетушитель всасывает пламя, выделяемые газы и даже источник пожара в вакуумную камеру. По мнению разработчиков, метод вакуумного тушения (VEM) максимально подходит для тушения огня в космических кораблях и подводных лодках — мало того, что он устраняет огонь, так он еще и не оставляет в воздухе вредных продуктов сгорания.

В настоящее время в космических кораблях и станциях разных стран используются огнетушители, распыляющие диоксид углерода. Они были выбраны из-за способности безопасно тушить огонь, вызванный электрическим замыканием — основной причиной пожаров в космосе. При всем этом, исследователи ищут им альтернативу, так как они несовершенны.

Минусы углекислотных огнетушителей:

  • они распыляют диоксид углерода и распространяют по замкнутому пространству продукты сгорания, поэтому экипажу необходимо время на надевание защитных масок;
  • впоследствии, для устранения вредных веществ из воздуха также требуется много времени;
  • их нужно часто заменять, что делает их непригодными для длительных космических миссий — например, для полетов на Марс.

Чем вакуумное тушение лучше других методов?

Возможно, в наземных условиях другие методы более эффективны и предпочтительны, но в замкнутых пространствах всасывание огня и продуктов сгорания в вакуумную камеру — самое то. Технология исключает необходимость надевания защитной маски, поэтому люди смогут потушить пожар сразу же после его обнаружения, пока он не нанес большой ущерб.

Исследователи считают, что вакуумные огнетушители будут полезны не только в космических кораблях и подводных лодках, но даже в помещениях, где важна стерильность. Например, их можно будет использовать в операционных, где вещества от других огнетушителей могут повредить дорогостоящее оборудование.

Как вы считаете, приживется ли новый тип огнетушителей? Может, вы видите в них минусы? Своим мнением можно поделиться в комментариях, или же в нашем Telegram-чате.
