Human impact on the system engineering of human space missions

Abstract [en]

Concurrent Engineering (CE) is an effective method used by the Concurrent Design Facility (CDF) at ESA/ESTEC, when designing future space missions. The System Engineering (SE) approach used by the CDF is model based and the software infrastructure currently used is called the Integrated Design Model (IDM). It consists of a number of domain specific tools and data bases interlinked by means of several MS Excel® workbooks. More than 130 missions have been assessed in the CDF in the last ten years, of which only a small percentage are dedicated to Human Space Flights. For this reason the model has not yet been fully developed and exploited for human missions. In order to enhance the CDF’s capability in designing human space missions a new system-level discipline is created that deals with Human Systems Integration (HSI). The HSI discipline (workbook) includes parameters and models, giving extra system requirements and constraints to the design of several subsystems as well as to the overall system, and is a tool to perform Product Assurance (PA) by verifying the requirements. Parameters are defined from related standards, the study of existing literature, previously performed human missions, by understanding the human body and the requirements that it gives its surrounding and how it is affected by the space environment. The goal of the HSI discipline is to elaborate on specific mission requirements and constraints in order to provide input to the design of the other subsystems as well as influencing the overall system design. By adding HSI as a discipline into the CDF’s IDM the engineers involved in the study and design of the mission are able to perform a more detailed conceptual design for a human space mission in the preliminary phases of the project’s life cycle.
