Title: The Effect of Impact Acceleration on the Crew during Splashdown by new-generation Reentry Space Capsules
Abstract: Recently, manned space capsules have been recognized as feasible human space vehicles. The Dragon capsule, developed by SpaceX a private company, already achieved several significant successes. The Orion capsule, developed by NASA, is going to be sent to a high-apogee orbit without crews for experimental purposes in September 2014. For such human-rated space capsules, the study of acceleration impacts against the human body during splashdown is essential to ensure the safety of crews. Moreover, it is also known that wearing a full pressure rescue suit significantly increases safety of the crew, compared to wearing a partial pressure suit. This is mainly because it enables the use of a personal life support system independently in addition to that which is installed in the space vehicle. However, it is unclear how the full pressure suit affects the acceleration impacts during splashdown, especially in the case of the Dragon and Orion capsules.
Therefore, the purpose of this work is to introduce preliminary investigation about the effect of the impact against the human body and G-load scenarios of the Dragon and Orion capsules during splashdown. The investigation finally shows the significant remark that the crewmembers may be more or less seriously injured in off-nominal G-load scenarios of these capsules. This work also introduces future plans of the experiments called impact sled tests. These tests will use an instrumented anthropomorphical dummy in order to determine if the safety and survivability of an astronaut can be improved by wearing a full pressure suit. These tests will be performed under the collaboration with Federal Aviation Administration (FAA) and Civil Aerospace Medicine Institute (CAMI).
