PART A2 PREFERRED DESIGN CONCEPT VOYAGER CAPSULE PHASE B FINAL REPORT VOLUME Ⅱ CAPSULE BUS SYSTEM

摘要

The purpose of this section is to examine the sensitive factors in terms of their influence on the Capsule Bus from the design to Martian operation.nThe initial internal burden of contamination of piece parts and materials significantly contributes to the total CBS burden, depen¬ding on the assembly environment and the timing of the Flight Acceptance (FA) heat cycle, which is used to reduce the accumulated bio-burden during assembly. Kith assembly in ultra-clean rooms (Class 100 or better) and late FA heat cycling, initial burdens represent the large proportion of contamination possibilities. This is particularly true of the CBS, which has a large number o£ connectors and handfinished piece parts.
