歼击机飞行员在飞行训练和作战时,常受加速度的影响.这种影响的主要原因是由于加速度时引起人体血液动力学的变化所造成.其中主要是正向加速度的影响.因为在飞行正向加速度时会使血液动力失去正常状态,血流发生由头向脚移注.这样,上体特别是脑有效血液循环量减少,而下肢血循环量增加,随着G Fighter pilots are often affected by acceleration during flight training and combat, mainly due to changes in the hemodynamics of the human body caused by accelerations, mainly due to the effect of forward acceleration, because at forward accelerations Will lose the normal state of hemodynamics, blood flow from the head to the foot transfer.Thus, the upper body, especially the brain to reduce effective blood circulation, while the lower limb blood circulation increased, with G
