摘要:
Embodiments of the present invention provide improved space utilization concepts for aircraft, and particularly to using under floor space created by the envelope designed to house an airstair system. For example, this space may be used to house and integrate one or more fuel cell system(s) and/or components, such as hydrogen tanks and/or the fuel cell body, such that the fuel cell system can deliver useful byproducts to support various aircraft functions. Additionally or alternatively, the space may be used to store other components.

摘要:
In order to protect the passengers of an airplane against the effects of depressurization of the cabin, breathing masks are fed with oxygen at a rate which is an increasing function of cabin altitude. Oxygen is fed via a constriction and an economizer bag, and an initial fraction only of the gases breathed out is caused to be re-breathed by collecting the initial fraction in a flexible re-breathing bag in communication with the mask. The re-breathing bag has a volume in inflated state which is not less than the total dead volume of the respiratory tract and the mask. A protective apparatus comprises a feed control unit supplying an adjustable flow rate to masks connected to a general pipe via respective economizer bags. A re-breathing bag retards re-breathing and stores only an initial fraction of the gases breathed out on each exhalation.
