Flight Dynamics and Equipment Improving the Tolerance to Flight Dynamic Factors

加速度对人体组织的作用,与其值、方向和作用持续时间,及其速度增长率相关。加速度可分为直线加速度、径向加速度和角加速度等。高机动飞机飞行产生较大的正向直线加速度使飞行员脑部血液流向下肢,以致脑部缺血,造成飞行员丧失意识。抗荷服能在发生正向直线过载时,对飞行员的腹部与腿部加压,阻止脑部血液流向下肢。

The action of the acceleration on the human depends on its value,direction,duration and onset rate.There are three kinds of acceleration,linear acceleration,radial acceleration and angular acceleration.During high speed maneuver flight,the generated great positive linear acceleration will cause downward flowing of the blood from the brain to the lower limbs;therefore,loss of consciousness of the pilot may be resulted in.At this time,the anti-G suit will function to give a pressure to the abdomen and legs of the pilot to prevent the blood from flowing downwards.
