HIGH CAPACITY CENTRIFUGE
High Capacity Centrifuge 1
High Capacity Centrifuge 2
The High Capacity Centrifuge (HCC) is a 120 ft. diameter arm capable of accelerating a 5000 lb. payload to 30 G's (38 rpm) to simulate launch and landing loads. The HCC is driven by one or two 0.93 Mw (1259 hp) DC motors operated in conjunction with a motor generator set. Using the facility's 7.5 ton monorail crane, test items are mounted on a special low profile tilt fixture on the arm's test platform. The low profile tilt fixture simplifies the handling operations necessary to properly orient the payload to the desired load vector. The facility is serviced by a Vishay data acquisition system.

Onboard the centrifuge arm, the VXI mainframe unit provides signal conditioning and data acquisition. In the HCC control room, a Windows PC provides test setup, instrumentation test control, data display, and data storage. The Vishay data system is capable of various combinations of 300 channels of strain, deflection, and acceleration measurements. Also digital video of the test platform is available for viewing and recording during the test.
