Analysis of spacelab 3 residual acceleration data

Academic Article

Abstract

  • A data reduction plan is being developed to efficiently process residual acceleration data, making such data more accessible to principal investigators of low-gravity experiments. Accelerometer data collected during the Spacelab 3 mission is being processed using a prototype version of this plan. The plan addresses various aspects of acceleration data analysis: the identification of disturbances that are intolerable to experiments, the investigation of acceleration orientations, the definition and characterization of the background acceleration corresponding to a given experiment time line, the isolation and examination of particular significant disturbances, and the identification of disturbance sources. Acceleration magnitude, frequency, and orientation are discussed: transient accelerations can have magnitudes as large as 10-2g with frequency components (from 4.5 x 10-3to 150 Hz) no greater than 10-3g. These accelerations fluctuate rapidly in orientation. The occurrence of disturbance sources in an orbiter is tentatively identified as a random process, whereas the response of the orbiter to given accelerations is considered deterministic. The need to continue monitoring of residual accelerations in orbiting space laboratories is stressed: future measurements are needed to establish acceleration characterizations of specific orbiters and to establish appropriate acceleration tolerance limits for specific experiment classes in low-gravity conditions. © 1990 by the American Institute of Aeronautics and Astronautics, Inc.
