Enhanced Simulation of Partial Gravity for Extravehicular Activity
Prior studies of human locomotion under simulated partial gravity have hypothesized that energy expenditure is increased in lunar gravity, as compared to that of Mars. This may be due to subjects having to expend excess energy for stability and posture control in the lower gravitational field. The physiological cause of this suspected ‘‘wasted energy’’ during locomotion in low gravity remains t...
متن کاملComputational simulation of extravehicular activity dynamics during a satellite capture attempt.
A more quantitative approach to the analysis of astronaut extravehicular activity (EVA) tasks is needed because of their increasing complexity, particularly in preparation for the on-orbit assembly of the International Space Station. Existing useful EVA computer analyses produce either high-resolution three-dimensional computer images based on anthropometric representations or empirically deriv...
متن کاملA new preoxygenation procedure for extravehicular activity (EVA).
A 10.2 psi staged-decompression schedule or a 4-hour preoxygenation at 14.7 psi is required prior to extravehicular activity (EVA) to reduce decompression sickness (DCS) risk. Results of recent research at the Air Force Research Laboratory (AFRL) showed that a 1-hour resting preoxygenation followed by a 4-hour, 4.3 psi exposure resulted in 77% DCS risk (N=26), while the same profile beginning w...
متن کاملa study on thermodynamic models for simulation of 1,3 butadiene purification columns
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
A Wearable Computer for Support of Astronaut Extravehicular Activity
A wearable situational awareness terminal (WearSAT) that provides text, graphics, and video to an astronaut via a near-eye display, and acts as a client on a wireless network, has the potential to enhance the ability of astronauts to perform useful work and cope with uncertainty during extravehicular activity (EVA). An initial implementation is described, including the supporting network archit...
