Morl Configuration, Maintenance, and Installation Concepts

Abstract

Manned spacecraft designed for long lifetime in space impose a unique requirement for inflight maintenance for all vehicle systems. The key factors in implementing onboard maintenance are accessibility to equipment, rapid fault detection and isolation, and modularized equipment packaging using a supply of interchangeable components. This paper discusses the general configuration of the Manned Orbital Research Laboratory (MORL) studied under contract NAS 1-3612, NASA Langley Research Center and also presents in digest form some conceptual maintenance, design and installation approaches.
