弹射座椅与飞行员系统重心测量技术

Measure technology of the center of gravity of ejection seat-pilot system

为解决火箭弹射座椅人椅系统在弹射出舱后的稳定调节问题 ,设计研制了新型电子人椅系统组合重心测量设备 ,建立了组合重心的俯仰累加测量与推导计算方法 ,并对 2 94名飞行员的人椅系统组合重心数据进行了测量和计算 .结果表明 ,研制的测量设备精确可靠 ,建立的方法便捷有效 ,并具有通用性 .研究结果已应用于弹射座椅的设计研制中 ,精度提高了 1 0倍 ,效率提高了

To solve the stability adjustment problem of pilot-seat system after ejecting from fight plane cabin, a new electronics equipment which can measure the combined center of gravity of pilot-seat system was designed and manufactured, a new pitching-progressive measure and calculate technique was founded, and the combined center of gravity of 294 pilots were measured. It shows that the new equipment is accurate and reliable, the technique is efficient and convenient, and they are both universal. The equipment and technique have been applied in the design and manufacture of ejection seat. It is proved that the precision is improved 10 times, while the efficiency 3 times.
