![]() Potential variables that could have affected the data were identified and a third round of testing was conducted in an attempt to eliminate and/or quantify the effects of these variables. The resultant data was compared using graphical and statistical analysis the results indicated a significant variance in values reported for a subset of the re-tested joints. In order to validate the method itself, a representative subset of the previous test was repeated, using the same information that would be available to space suit contractors, but set up and conducted by someone not familiar with the previous test. However, because the original test was set up and conducted by a single test operator there was some question as to whether this method was repeatable enough to be considered a standard verification method for Constellation or other future development programs. The same test method was levied on the Constellation space suit contractors to verify that their suit design met the requirements. This was done in an effort to develop joint torque requirements appropriate for a new Constellation Program space suit system. In 2009 and early 2010, a test method was developed and performed to quantify the torque required to manipulate joints in several existing operational and prototype space suits. Space Suit Joint Torque Measurement Method Validation The focus of this paper is to discuss trends observed during data analysis. The results were then reviewed and CSSE joint torque requirement values were selected. Data was collected data from 16 different joint movements of each suit. This test utilized the following space suits: Extravehicular Mobility Unit (EMU), Advanced Crew Escape Suit (ACES), I- Suit, D- Suit, Enhanced Mobility (EM)- ACES, and Mark III (MK-III). A joint torque test was conducted to determine a baseline for current advanced space suit joint torques. One method focuses on range of motion and the second method centers on joint torque. Two methods were chosen to define mobility requirements for the Constellation Space Suit Element (CSSE). These two measurements describe how the suit moves and how much force it takes to move. Mobility can be broken down into two parts: range of motion (ROM) and torque. As mobility increases, the astronaut can perform tasks for longer durations with less fatigue. Results and Analysis from Space Suit Joint Torque TestingĪ space suit's mobility is critical to an astronaut's ability to perform work efficiently. The results of the retest will be used to determine if further testing and modification is necessary before the method can be validated.
