Abstract

A knowledge of the quasi-steady acceleration environment on the NASA Space Shuttle Orbiter is of particular importance for materials processing experiments which are limited by slow diffusive processes. The quasi-steady (less than 1 HZ) acceleration environment on STS-73 (USML-2) was measured using the orbital acceleration research experiment (OARE) accelerometer. One of the facilities flown on USML-2 was the crystal growth furnace (CGF), which was used by several principal investigators (PIs) to grow crystals. In this paper the OARE data mapped to the sample melt location within this furnace is presented. The ratio of the axial to radial components of the quasi-steady acceleration at the melt site is presented. Effects of orbiter attitude on the acceleration data is discussed.
