Abstract

Zespół silnika turbowentylatorowego, zawiera silnik właściwy (12), wentylator (14), kanał zewnętrzny wentylatora otaczający częściowo silnik właściwy i wentylator oraz system upustowy. System upustowy obejmuje pierwszy obieg upustowy skonfigurowany do odprowadzania sprężonego powietrza z silnika właściwego i kierowania strumienia do pierwszego obiegu wymiennika ciepła oraz drugi obieg upustowy skonfigurowany do odprowadzania powietrza z kanału zewnętrznego wentylatora i kierowania strumienia do drugiego obiegu wymiennika ciepła. Drugi obieg upustowy zawiera kanał upustowy zawierający wlot kanału i wylot kanału połączony za pośrednictwem zaworu z wymiennikiem ciepła w sposób umożliwiający przepływ. Kanał upustowy zawiera również przewód tłumienia akustycznego przebiegający od kanału upustowego przed zaworem, do kanału zewnętrznego wentylatora i zwymiarowany odpowiednio do tłumienia wahań ciśnienia wewnątrz drugiego obiegu upustowego, gdy zawór jest przynajmniej częściowo zamknięty.
