，安全检查的范围已经超过了机载分子筛制氧系统（OBOGS）（该系统由霍尼韦尔公司
提供）。尽管通告中描述的还是“机载分子筛制氧系统（OBOGS）安全调查”，这一调
查自5月3日所有的 F-22因安全问题停飞后，现在已经“不局限于”某一个具体的系统
，空军战斗司令部（ACC）在回复提问的邮件中说到。
“我们仍然在继续努力以确定到底是哪一个部分出现了问题”，空军战斗司令部称。“
明确的将这一问题归咎于机载分子筛制氧系统（OBOGS）是不准确的”。停飞最初的原
因是因为5位F-22飞行员报告了氧气系统可能存在故障，包括一架F-22在进近阶段擦到
了树梢。当降落后飞行员无法回忆这起事故，这就是一种典型的缺氧症状。
分子筛制氧系统（OBOGS）并不是供给飞行员所需氧气的唯一装置。它安装在飞行员的
座位后面，通过一种分子筛材料将来自于冲压空气中的氧气分离出来而形成富氧。在分
子筛制氧系统（OBOGS）和飞行员的肺之间，过滤后的氧气经两个主要的部件——MBU-
22P氧气面罩和呼吸/抗荷一体化调节器（BRAG）。后者确... 阅读全帖 |

OBOGS eliminates the need for LOX by utilizing
bleed air from the engine and separating its
components through a two-bed molecular
sieve pressure swing adsorption (PSA) technology.
The OBOGS provides and generates a continuous
supply of 93% breathing oxygen. The
OBOGS interfaces with the conditioned bleed
air supply and the 28 VDC electrical supply. |

Return of the Raptor:
The F-22 fleet will probably be up and running again "soon," said Chief of
Staff Gen. Norton Schwartz. In an interview Tuesday, Schwartz said he
expects a report next week from the Air Force Scientific Advisory Board task
force headed by retired Gen. Gregory Martin, which will offer a way forward
regarding questions about the F-22's o... 阅读全帖 |

而且说实话，现在能投的公司也没什么OBOG。。
话说你明年考的话强烈推荐TK两家。。 |

KADENA AIR BASE, Japan (AP) — Years before F-22 pilots began getting dizzy

fatal crash, before two more went on television to say the plane was so
unsafe they refused to fly it, a small circle of U.S. Air Force experts knew
something was wrong with the prized stealth fighter jet.
