Найден способ избавиться от ужасного шума вакуумных туалетов в самолетах

Полеты на самолетах едва ли можно назвать приятным времяпровождением — мало того, что многие пассажиры могут пугаться большой высоты, так некоторые из них могут также испугаться ужасного шума вакуумного туалета. Дело в том, что современные самолеты стали очень тихими, а санузлы не модифицировались уже более 60 лет. Их улучшением решили заняться инженеры из Университета Бригама Янга — они предложили внести в конструкцию вакуумных туалетов всего лишь пару небольших изменений, и они действительно заметно уменьшили их шум.

Найден способ избавиться от ужасного шума вакуумных туалетов в самолетах

Как бы противно это не звучало, но в самолетах все отходы собираются в один резервуар. Они всасываются мощным и громким насосом, а дополнительный шум возникает из-за движений разнообразных клапанов. По расчетам исследователей, вещества проходят по трубам с сумасшедшей скоростью 500 километров в час — возникающий шум не могут заглушить даже толстые стены.

Исследователи заметно ослабили шум, изменив всего лишь две детали. Ранее отвод унитаза располагался строго под углом в 90 градусов, и часть неприятного шума была связана именно с этим резким поворотом. Инженеры легко решили эту проблему, просто увеличив угол изгиба трубы. Вторая проблема заключалась в грохоте открывающегося промывочного клапана — она была решена банальным увеличением расстояния между ним и унитазом.

В результате всего лишь пары изменений, уровень шума вакуумного туалета был снижен на целых 16 децибел. Когда именно новая система будет применена в самолетах, пока неизвестно. Возможно, авиакомпании не особо заинтересованы в повышении комфорта для пассажиров, но работа инженеров может дать толчков на разработку наземных систем, в которых используется минимальное количество воды для смыва.
