The invention relates to an aircraft comprising: at least one secondary structure separating an inner region from an outer region; and a hydrogen supply device (26) connecting the hydrogen storage tank (24) and the power device (20), comprising at least one section (42) equipped with a shut-off valve (34, 34 ') to isolate it in the event of a leak. The section (42) comprises at least one outer enclosure, at least one inner element located in the outer enclosure and transporting hydrogen, and at least one inner region (Zi) located between the inner element and the outer enclosure. The hydrogen supply device (26) comprises at least one ventilation system (46) configured to be able to discharge gases present in the inner region (Zi) towards an outer region of the secondary structure. In the event of a leak, the ventilation system (46) allows the hydrogen present in the interior region (Zi) to be expelled to reduce its concentration.
本发明涉及一种飞行器,其包括:将内部区域与外部区域分隔开的至少一个次级结构;以及连接储氢罐(24)和动力装置(20)的氢供应装置(26),其包括配备有截止阀(34、34')以在发生泄漏的情况下将其隔离的至少一个部段(42)。该部段(42)包括至少一个外部封壳、位于外部封壳中并输送氢的至少一个内部元件以及位于内部元件和外部封壳之间的至少一个内部区域(Zi)。氢供应装置(26)包括至少一个通风系统(46),其被构造为能够将内部区域(Zi)中存在的气体朝次级结构的外部区域排放。在发生泄漏的情况下,通风系统(46)允许将内部区域(Zi)中存在的氢排出以降低其浓度。
