Abstract

A series of vacuum simulation tests were conducted to characterize the possible contamination of payload surfaces due to separation of the Pegasus fairing. This paper presents the test philosophy, experimental approach and the contaminant levels found, compared to MIL-STD- 1246B. These tests show that the Pegasus fairing separation using the frangible base joint and nose bolt nut results in Level 500 payload surfaces. The source of Zn particles near the bottom of the test payload needs to be found.
