The invention relates to an aircraft. The aircraft has a structure, a fuselage, a floor separating the fuselage in two, wherein the floor has openings, and, for each opening, a shut-off system having a flap hinged on the structure between a standby position in which the flap does not shut off the opening and a protective position in which the flap shuts off the opening, a return arrangement that urges the flap into the protective position and a retaining element that keeps the flap in the standby position and breaks when its temperature exceeds its melting point. Thus, when a high-temperature gas flow reaches the retaining element and this high temperature is higher than the melting point of the retaining element, the latter breaks and releases the flap, which shuts off the opening.

    本发明涉及一种飞行器,所述飞行器具有结构体、机身、将机身一分为二的地板,其中,所述地板具有开口,并且,对于每个开口,关闭系统具有:翻板,所述翻板在待用位置与保护位置之间铰接在所述结构体上,在所述待用位置,所述翻板不关闭所述开口,在所述保护位置,所述翻板关闭所述开口;复位器件,所述复位器件促使所述翻板进入所述保护位置;以及固位元件,所述固位元件将所述翻板保持在所述待用位置,并且在所述固位元件的温度超过其熔点时破裂。因此,当高温气流到达所述固位元件并且这个高温高于所述固位元件的熔点时,所述固位元件破裂并且释放翻板,这会关闭所述开口。
