Centrifuge Testing of the Integrated Closed Environmental Control System (ICECS) 941521

The Dynamic Environment Simulator (DES), a man-rated centrifuge, was used to support testing of the Integrated, Closed Environmental Control System (ICECS). DES drive and support systems were modified to satisfy ICECS power, cooling and control requirements. Digital control of the DES drive systems allowed ICECS exposure to acceleration magnitudes approaching 10 G for extended periods. During latter phases of testing, G profiles were customized as indicated by the results to completely determine ICECS system dynamics. The DES provided a flexible, low cost test bed with all test objectives satisfied on time and on budget.
