| Keywords: Reduced Gravity Walking Simulator DVIDS694183.jpg en A test subject being suited up for studies on the Reduced Gravity Walking Simulator located in the hanger at Langley Research Center The initial version of this simulator was located inside the hanger Later a larger version would be located at the Lunar Landing Facility The purpose of this simulator was to study the subject while walking jumping or running Researchers conducted studies of various factors such as fatigue limit energy expenditure and speed of locomotion Francis B Smith wrote in his paper Simulators For Manned Space Research I would like to conclude this talk with a discussion of a device for simulating lunar gravity which is very effective and yet which is so simple that its cost is in the order of a few thousand dollars at most rather than hundreds of thousands With a little ingenuity one could almost build this type simulator in his backyard for children to play on The principle is if a test subject is suspended in a sling so that his body axis makes an angle of 9 1/2 degrees with the horizontal and if he then stands on a platform perpendicular to his body axis the component of the earth's gravity forcing him toward the platform is one times the sine of 9 1/2 degrees or approximately 1/6 of the earth's normal gravity field That is a 180 pound astronaut standing on the platform would exert a force of only 30 pounds - the same as if he were standing upright on the lunar surface Published in James R Hansen Spaceflight Revolution NASA Langley Research Center From Sputnik to Apollo NASA SP-4308; Francis B Smith Simulators For Manned Space Research Paper for 1966 IEEE International Convention New York NY March 21-25 1966 NASA Identifier L63-9964 2009-09-24 Glenn Research Center https //www dvidshub net/image/694183 694183 2012-10-10 13 13 WASHINGTON DC US PD-USGov Langley Research Center Images from DoD uploaded by Fæ | ||||
