新装置或能降低战斗机飞行员失去意识情况

Two different physiological¹ situations can lead to a pilot's loss of consciousness,says Elbit Systems senior research and development director, retired² fighter pilot Yaron Kranz.

埃尔比特系统公司高级研发总监，退休战斗机飞行员雅隆·克兰兹表示两种截然不同的身体状况会导致飞行员意识的丧失。

“One is G-LOC' or G Loss of Consciousness, and the other one is hypoxia which is lack of oxygen to the brain.”

“一种是G-LOC或G致意识丧失,另一种则是大脑缺氧。”

G-LOC happens during sharp turns and high-speed accelerations³, when centrifugal force reduces the normal flow of blood to the pilot's brain.

G-LOC是由急转弯和高速加速引起,离心力会使正常流动至飞行员大脑的血液减少。

At that speed, loss of control of the aircraft proved fatal for many pilots.

在那样的速度下,飞机的失控对许多飞行员而言是致命的。

Hypoxia, or lack of oxygen, can affect anyone at high altitudes, which is why passenger planes are equipped with oxygen masks, deployed⁴ in case of loss of cabin pressure.

而组织缺氧，即缺氧可在高海拔影响任何人,这就是为什么客机配备氧气面罩,以防失去机舱气压的缘故。

Current devices for preventing these dangerous situations are bulky so Elbit Systems and a startup called LifeBEAM developed a system called Canary.

当前预防这些危险情况发生的设备体积都非常大,因此埃尔比特系统公司同一家名为LifeBEAM的公司研发了一套被称为金丝雀的系统。

It uses small, non-invasive sensors⁵ built into the pilot's helmet.

它在飞行员的头盔内配备了小巧、不可侵入式的内置传感器。

“The pilot doesn't have to do anything in order to activate⁶ those sensors and they are small enough and wise enough to give the information in order to gather the physiological data that is required.”

“飞行员不需要做任何事情就能激活这些传感器而且它们足够小巧,足够机敏，能发送收集所需的身体数据信息。”

When the danger is imminent⁷, the system flashes an alert message on the helmet's visor.

当危险迫在眉睫,系统会在头盔的面罩中发送警告消息。

If it senses that the pilot has lost consciousness,it signals the plane's computer to activate the autopilot.

如果系统感知到飞行员已失去知觉,它会向机上电脑发送信号激活自动驾驶。

 

Elbit Systems is now developing its Canary device for advanced U.S. F-35 fighter jets and other Western aircraft.

埃尔比特系统公司现在正为美国先进的F-35战斗机及其他西方战机研发金丝雀装置。
