While flying high above Earth’s surface, jet fighter pilots may suffer loss of eyesight for brief periods. Some pilots may even lose
consciousness -- not being able to recognize what is happening around them. These experiences, commonly called
blackouts, can lead to tragic results.
飛行員在地球表面高空飛行時(shí)可能會(huì)出現(xiàn)短暫的視力消失。一些飛行員甚至失去知覺(jué),不能夠察覺(jué)身邊發(fā)生的事情。這些經(jīng)歷,通常叫做“黑視”,能夠?qū)е卤瘎“l(fā)生。
Now, an Israeli company says it has developed a device that could save pilots’ lives at such times.
現(xiàn)在,一位以色列公司表示發(fā)明了一種新裝備,這種裝備可以在飛行員失去知覺(jué)時(shí)挽救他們的生命。
Yaron Kranz is senior research and development director at Elbit Systems. He is also a retired fighter pilot. He says two different situations can lead to a pilot’s loss of consciousness.
雅讓·克蘭茲是艾比特系統(tǒng)公司的最高研究人員和發(fā)明總指導(dǎo)人。他同時(shí)也是一名退休戰(zhàn)斗飛行員。他說(shuō)了兩種可以使飛行員失去知覺(jué)的情況。
“One is ‘G-LOC’ or G Loss of Consciousness, and the other one is hypoxia,which is lack of oxygen to the brain.”
其中一種情況是“意識(shí)喪失”,另一種是缺氧,即大腦供氧不足。
G-LOC happens when the airplane is making a sharp turn or speeding up veryquickly. During these periods,
centrifugal force reduces the normal flow of blood to the pilot’s brain. At high speeds, loss of control of the aircraft hasproved deadly for many pilots.
當(dāng)飛機(jī)急速轉(zhuǎn)彎或加速時(shí)會(huì)出現(xiàn)意識(shí)喪失,在這段時(shí)間內(nèi),離心力減少了飛行員體內(nèi)流向心臟的血液的正常流動(dòng)。在高速下,飛機(jī)失控對(duì)飛行員來(lái)說(shuō)極其危險(xiǎn)。
Hypoxia, or lack of oxygen, can affect anyone at extreme heights. That is whypassenger planes are equipped with oxygen masks. Passengers are always told before flying to put on the masks in case of a sudden loss of air pressure.
低氧,或者缺氧,在一定高度下能夠影響任何人。這就是為什么客機(jī)都備有氧氣面具的原因,飛機(jī)起飛前,乘客往往被告知戴上氧氣面具以防飛機(jī)突然失壓。
Current devices for preventing such dangerous situations are very large. So Elbit Systems and a small start-up company, called Life BEAM, developed a system they are calling Canary. It uses small, non-invasive sensingequipment. Yaron Kranz says the sensors are built into the helmet worn by the pilot.
目前的裝備應(yīng)對(duì)這種情形還存在較大危險(xiǎn)。因此,艾比特公司和一家剛剛發(fā)展的稱作“生命之光”小公司研發(fā)了一種叫“金絲雀”的系統(tǒng)。該系統(tǒng)采用小型的,不具侵入性的感覺(jué)器材。雅讓·克里茲表示,這些感應(yīng)器植在飛行員所戴的頭盔里。
“The pilot doesn’t have to do anything in order to activate those sensors and they are small enough and wise enough to give the information to gather the physiological data that is required.”
這些感應(yīng)器并不需要飛行員額外啟動(dòng),且體積小,又能智能地手機(jī)所要求的生理數(shù)據(jù)。
By physiological data, he means information related to the processes and activities that keep the person alive. When the danger is real, the system sends a message to the
visor on the front of the helmet. If it senses that the pilot has lost consciousness, it tells the plane’s computer to activate the autopilot. The autopilot will then take control of the plane’s movement until thepilot wakes up.
雅讓所提到的生理數(shù)據(jù),是指能夠保持一個(gè)人活著的關(guān)于進(jìn)程和活動(dòng)的信息。當(dāng)危險(xiǎn)存在時(shí),系統(tǒng)就會(huì)向頭盔前沿發(fā)送信息。如果感應(yīng)器感到飛行員已失去知覺(jué),那么它將會(huì)啟動(dòng)飛機(jī)的電腦自動(dòng)飛行員。自動(dòng)飛行員接著將會(huì)操控飛機(jī)飛行知道飛行員蘇醒過(guò)來(lái)。
Elbit Systems is now developing its Canary device for U.S. F-35 fighter jetsand other aircraft.
艾比特系統(tǒng)目前正為美國(guó)的F-35戰(zhàn)斗機(jī)及其他機(jī)型研發(fā)“金絲雀”裝備。
