System Features of a Space Station Prototype Environmental Thermal Control and Life Support System

Abstract

The preliminary design phase of the Space Station Prototype Environmental Thermal Control and Life Support System Program has been completed, and the detailed design of the system is underway. This paper describes some of the specific system features which have been incorporated to solve the problems of maintainability, to ensure reliability without excessive weight penalties, and to achieve fault detection and isolation through use of the capabilities of an onboard checkout system.
