    • PROBLEM TO BE SOLVED: To provide a method and arrangement for adjusting nitrogen and oxygen concentrations within regions of an aircraft. SOLUTION: The method includes separating nitrogen from ambient air onboard an aircraft thereby establishing a high-concentration nitrogen supply source 90 and then dispensing high-concentration nitrogen from the supply source 50 to a fire-susceptible, non-habitable region of the aircraft where the high-concentration nitrogen is stored thereby decreasing the capability for the atmosphere therein to support combustion. Oxygen is also separated from the ambient air thereby establishing a high-concentration oxygen supply source 80 that is dispensed to an occupant cabin 50 of the aircraft thereby increasing the level of oxygen concentration within the cabin to a level greater than the naturally occurring concentration of oxygen at the experienced internal cabin pressure. When it is determined that reduced oxygen concentration is required in the occupant cabin 50, the stored high-concentration nitrogen is moved into the passenger cabin 50 diluting the oxygen-elevated environment.

    • 要解决的问题:提供一种用于调整飞行器的区域内的氮和氧浓度的方法和装置。 解决方案:该方法包括从飞机上的环境空气中分离氮气,从而建立高浓度氮气供应源90,然后将高浓度氮气从供应源50分配到火源易受害的不可居住区域 存储高浓度氮的飞机,从而降低其中的气氛以支持燃烧。 氧气也与环境空气分离,从而建立高浓度氧供应源80,其被分配到飞机的乘客舱室50,从而将舱室内的氧浓度水平提高到大于天然存在的氧浓度 在经验丰富的内部舱内压力。 当确定在乘员舱50中需要降低的氧气浓度时,将储存的高浓度氮气移动到客舱50中,以稀释氧气升高的环境。 版权所有(C)2009,JPO&INPIT
