The facility is a unique testbed that allows optimization of human performance, failure mode testing, evaluation of crew technologies and optimization of human systems integration. Areas adjacent to the centrifuge room are available for subject preparation, subject monitoring, pre-and post-centrifugation testing, and data collection. The centrifugal force also increases with the distance from the axis of rotation. Doubling the speed of rotation increases the centrifugal force by a factor of four. Multiple payloads can be placed along the arms to simultaneously obtain data from specimens or hardware at multiple g-levels. The g force acting on particles is exponential to the speed of rotation defined as revolutions per minute (RPM). The universal rail mounting system enables novel experiment configurations to be placed at any radius along arm, allowing comparison of radius, acceleration gradients, or coriolis effects. Mounted on the 58-foot diameter centrifuge are three enclosed cabs. The maximum g-level attainable is dependent upon the mass of the specific payload. The 20-G Centrifuge is capable of producing forces up to 20 times that of terrestrial gravity. Data acquisition systems have also been continuously upgraded to provide custom capabilities. It was renovated in the early 1990s, and equipped with a drive system that enables programmable acceleration profiles. The g force rpm conversion formula is as follows: RCF 1.118 10 r (rpm) RCF: Relative Centrifuge Force, in 'g' r : Rotor radius, in 'cm' rpm: Rotation speed, rotations per minute, in 'rpm'. Use Beckman Coulter rotors speed converters here. RCF is positively related with the rotor radius and the rotation speed of the centrifuge. RPM TO GRAM-FORCE (rpm TO gf) CHART 1 RPM in gram-force 1.69952702 rpm 10 RPM in gram-force 16.99527022 rpm 50 RPM in gram-force 84.97635108 rpm 100. There are several ways to convert g force (RCF) into revolutions per minute (RPM) and vice versa: 1. ![]() RCF is positively related with the rotor radius and the rotation speed of the centrifuge. You can use the following equation for the conversion : g Force (RCF) (rpm) × 1.118 × 10. The 20-G facility was designed in the 1960s and used for the research during the era of the biosatellite missions. G force refers to Relative Centrifugal Force (RCF). G force refers to Relative Centrifugal Force (RCF). The 20-G Centrifuge offers unique, innovative ways to conduct research and training to solve real world problems related to the effects of acceleration on systems.
