Available in PDF, EPUB and Kindle. Book excerpt: Spacesuit Assemblies (SSAs) provide life support for human operators performing extravehicular activities (EVAs). The overall goal of this research was to investigate three research questions to address gaps in the field of spacesuit assembly (SSA) evaluations: [1] What are the mobility and agility limitations causing operators to experience performance decrements when wearing a SSA?; [2] What is causing operators to experience increased joint torques?; and [3] How does the distributed weight of an SSA, transferred to the operator, affect performance? This research leveraged both experimental and computational modeling capabilities to evaluate SSAs with a human-centered focus, in ways previously unachievable. The space suit evaluated for this research was NASA's Mark III (MkIII) Planetary Technology Demonstrator SSA, built to test the next generation in planetary exploration capabilities, improving upon Apollo era technology. The hip brief assembly (HBA) is built with three nested bearings, each with a single rotational degree of freedom that together provide the range of motion, walking efficiency, and kneeling capabilities. An initial investigation, combining a pilot study and supporting modeling, revealed limitations in the current human-SSA system that may impair the operator's mobility/stability and agility. Limitations identified and investigated in this thesis include SSA degrees of freedom (DOFs), the SSA range of motion (ROM) envelope, the bearing resistances, the SSA component's inertial effects, the SSA mass load transfer dynamics, and suit fit. The SSA architecture was modeled as part of the thesis, creating a tool that was useful in the investigation of the human-suit system. The model relied on SSA component geometries and inherent mass/inertia and bearing resistance characteristics to output joint dynamics, rather than requiring those dynamics as an input (which would require extensive experimental setups). The model was used to isolate components that contribute to the measured operator performance degradations and to quantify the extent of their contributions. These investigations lead to suggestions for design requirements and evaluation techniques that can guide future SSA development and evaluations.
Download or read book Hazard Analysis for the Mark Iii Space Suit Assembly Used in One G Operations written by Kate Mitchell and published by BiblioGov. This book was released on 2013-07 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Hazard Analysis document encompasses the Mark III Space Suit Assembly (SSA) and associated ancillary equipment. It has been prepared using JSC17773, "Preparing Hazard Analyses for JSC Ground Operation," as a guide. The purpose of this document is to present the potential hazards involved in ground (23 % maximum O2, One-g) operations of the Mark III and associated ancillary support equipment system. The hazards listed in this document are specific to suit operations only; each supporting facility (Bldg. 9, etc.) is responsible for test specific Hazard Analyses. A "hazard" is defined as any condition that has the potential for harming personnel or equipment. This analysis was performed to document the safety aspects associated with manned use of the Mark III for pressurized and unpressurized ambient, ground-based, One-g human testing. The hazards identified herein represent generic hazards inherent to all standard JSC test venues for nominal ground test configurations. Non-standard test venues or test specific configurations may warrant consideration of additional hazards analysis prior to test. The cognizant suit engineer is responsible for the safety of the astronaut/test subject, space suit, and suit support personnel. The test requester, for the test supported by the suit test engineer and suited subject, is responsible for overall safety and any necessary Test Readiness Reviews.

This book was released on 2019-01-22 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The operational pressure range is the range to which the suit can be nominally operated for manned testing. The top end of the nominal operational pressure range is equivalent to 1/2 the proof pressure. Structural pressure is 1.5 times the specified test pressure for any given test. Proof pressure is the maximum unmanned pressure to which the suit was tested by the vendor prior to delivery. The maximum allowable working pressure (MAWP) is 90% of the proof pressure. The pressure systems RVs are set to keep components below their MAWPs. If the suit is pressurized over its MAWP, the suit will be taken out of service and an in-depth inspection/review of the suit will be performed before the suit is put back in service. The procedures outlined in this document should be followed as written. However, the suit test engineer (STE) may make redline changes real-time, provided those changes are recorded in the anomaly section of the test data sheet. If technicians supporting suit build-up, check-out, and/or test execution believe that a procedure can be improved, they should notify their lead. If procedures are incorrect to the point of potentially causing hardware damage or affecting safety, bring the problem to the technician lead and/or STE s attention and stop work until a solution (temporary or permanent) is authorized. Certain steps in the procedure are marked with a DV, for Designated Verifier. The Designated Verifier for this procedure is an Advanced Space Suit Technology Development Laboratory technician, not directly involved in performing the procedural steps, who will verify that the step was performed as stated. The steps to be verified by the DV were selected based on one or more of the following criteria: the step was deemed significant in ensuring the safe performance of the test, the data recorded in the step is of specific interest in monitoring the suit system operation, or the step has a strong influence on the successful completion of test objectives.
