![]() 2, to evaluate crew injury risk while suited and restrained in the Orion seat by using specialized anthropometric test devices, or ATDs, also known as a crash test dummy, said Perry. 1, structural integrity of the suit and its critical components, and No. The testing here is really key to that next step of a human occupant flying in the Orion spacecraft as part of their continuing missions to go to … the moon and beyond during the whole Artemis program. “That seat we're going to test is a replica of the flight design that will be used in future Artemis missions. The objective of the testing, Perry said, is to gauge the structural integrity of the suit and the seat and to ensure its safety. That way if they see a problem with a design after a laboratory facility test, it's easy to go back and make changes and come back in and test.” “This saves lives, equipment and money,” Perry said. This gives the testing team an idea of potential areas of crew injury and allows changes to be made. This allows crew safety personnel to address any issues that may present themselves in a more cost-effective manner than other testing options.Īnother advantage is being able to run the system in a laboratory environment, where multiple tests in various orientations and configurations can be assessed. The HIA allows AFRL and NASA to assess various landing impact scenarios across all three - x, y and z - coordinate axes of the seat and enable researchers to examine how the seats and flight suits interact with one another and what affect those interactions may have on the crew. “This horizontal accelerator is currently the only known facility of its kind that can conduct extensive biodynamic research on instrumented ATDs and volunteer human subjects,” Perry said. Using only parachutes to reduce speed, the Orion crew module will slow from nearly 25,000 miles per hour to around 20 during reentry and splashdown in the Pacific Ocean. The Horizontal Impact Accelerator, or HIA, at AFRL’s Biomedical Impact of Flight Branch, tested multiple landing scenarios to gauge how the high-energy, low duration events inherent to the Orion spacecraft’s landings might affect the crew of the Artemis II mission.
