Crew Impact Attenuation Testing
猎户座乘员舱冲击衰减测试
A successful test of the Orion crew module's energy absorbing strut concept, was performed June 9, 2009, at the Landing and Impact Research Facility, also known as the gantry. The 20,000-pound (9,072 kg) apparatus, called the Crew Impact Attenuation System Test Article, represents the Orion crew module seat pallet that will accommodate 4-6 astronauts.
2009.6.9,猎户座乘员舱能量吸收支柱的测试成功完成。测试是在着陆和冲击研究设施上(又名测试桶架)进行的。乘员舱冲击衰减系统测试对象的质量是9072kg——新的猎户座乘员舱能容纳4-6名宇航员。
The test article was dropped from 18-feet (5.5 m) onto crushable honeycomb material,which is sized to represent various landing conditions Orion could face. The energy-absorbing struts will reduce loads felt by the crew during landing.
测试样本从5.5米高空坠落到蜂窝状可压碎支撑物上(上图的下方支撑物就是——gohomeman1译注),用以模拟猎户座乘员舱着陆时可能面临的各种状况。这种能量吸收支柱将减少着陆时宇航员的碰撞冲击感觉。
