弹射救生的最终目的是在飞机处于不可挽回状态下拯救飞行员的生命。军事航空的实践证明,高性能的弹射救生防护装备可使飞行员在训练和战斗中充分发挥飞机的效能。飞行员弹射救生的成功,可保持飞行员的数量,也能有力地鼓舞飞行部队的士气。弹射救生防护装备与空军的战斗力是密切相关的。因此,世界各军事强国均投入巨大的人力与财力来提高弹射救生装备的性能。随着飞机性能的不断提高,要求弹射救生防护装备的安全救生包线 The ultimate goal of catapult rescue is to save the pilot’s life while the aircraft is in an irreparable condition. Military aviation has proven that high-performance ejection lifesaving equipment enable pilots to fully exploit aircraft performance during training and combat. The success of the pilot’s catapult rescue, which maintains the number of pilots, can also be a powerful boost to the morale of the flying forces. Ejection life-saving protective equipment and the Air Force’s combat effectiveness are closely related. Therefore, all the world’s military powers have devoted tremendous manpower and financial resources to improve the performance of catapult equipment. As the performance of the aircraft continues to increase, it is required that a safe life-saving envelope of the life-saving equipment be ejected
