  • Engineering of the LISA Pathfinder mission—making the experiment a practical reality
    Classical and Quantum Gravity, 2009
    Co-Authors: Carl Warren, Neil Dunbar, Mike Backler
    Abstract:

    LISA Pathfinder represents a unique challenge in the development of scientific spacecraft—not only is the LISA Test Package (LTP) payload a complex integrated development, placing stringent requirements on its developers and the spacecraft, but the payload also acts as the core sensor and actuator for the spacecraft, making the tasks of control Design, software development and system verification unusually difficult. The micro-propulsion system which provides the remaining actuation also presents substantial development and verification challenges. As the mission approaches the system Critical Design Review, flight hardware is completing verification and the process of verification using software and hardware simulators and test benches is underway. Preparation for operations has started, but Critical milestones for LTP and field effect electric propulsion (FEEP) lie ahead. This paper summarizes the status of the present development and outlines the key challenges that must be overcome on the way to launch.

  • 3.4.4 THE HUMAN FACTORS ENGINEERING SPECIALTY WITHIN THE SYSTEMS ENGINEERING PROCESS
    INCOSE International Symposium, 1995
    Co-Authors: Christopher Rogers, Kristina Densler, Mary Englert, Taylor King, Michael Tulloch
    Abstract:

    One mission of the Human Factors Engineering (HFE) specialty is to ensure that all user requirements have been identified and that developed information systems and products can be operated and maintained effectively, efficiently, and safely, and can achieve the system mission. As part of efforts to reach greater maturity in Systems Engineering, the Human Factors Engineering process has been integrated into the Systems Engineering process. This is accomplished by recognizing where the services of Human Factors Engineering personnel are necessary and how they should be effectively applied during systems development, accommodating cost concerns. This paper identifies the characteristics of programs that alert Systems Engineering to seek Human Factors Engineering involvement. It describes the Human Factors Engineering process and products, emphasizing those activities that HFE supports within the traditional Systems Engineering process (i.e., Concept of Operations). It describes Human Factors Engineering activities from contract award through Critical Design Review (CDR).

  • BepiColombo Mercury Magnetospheric Orbiter Flight Model Thermal Analysis
    42nd International Conference on Environmental Systems, 2012
    Co-Authors: Hiroyuki Ogawa, Tsutomu Yamazaki, Akira Okamoto, Naoko Iwata, Shun Okazaki
    Abstract:

    The BepiColombo MMO (Mercury Magnetospheric Orbiter) flight model thermal Design and the flight prediction are presented. The MMO Thermal Test Model (TTM) was built according to the Design at PDR (Preliminary Design Review). MMO TTM was tested in a series of thermal testing. The geometrical and thermal mathematical models (GMM/TMM) were correlated in accordance with the test results. The flight model (FM) thermal Design was modified from the PDR Design according to the configuration change after PDR and the outcome of the thermal tests. The GMM/TMM for FM was prepared for the flight prediction for CDR (Critical Design Review) on the basis of the correlation and the hardware modifications. The verification of GMM/TMM for FM will be done by the additional TTM test and the FM thermal test. The final flight prediction will be available between the FM thermal test and the launch.
