    SYSML BASED CUBESAT MODEL DESIGN AND INTEGRATION WITH THE HORIZON SIMULATION FRAMEWORK

    This thesis examines the feasibility of substituting the system input script of Cal Poly’s Horizon Simulation Framework (HSF) with a Model Based Systems Engineering (MBSE) model designed with the Systems Modeling Language (SysML). A concurrent student project, SysML Output Interface Creation for the Horizon Simulation Framework, focused on design of the HSF Translator Plugin which converts SysML models to an HSF specific XML format. A SysML model of the HSF test case, Aeolus, was designed. The original Aeolus HSF input script and the translated SysML input script retained the format and dependency structure required by HSF. Both input scripts returned identical results and thus validated the feasibility of linking SysML with HSF through the HSF Translator Plugin. A second SysML model of the Cal Poly CubeSat mission, ExoCube, was also designed and converted into an HSF input script. The ExoCube input script also retained the format and dependency structure required by HSF. This demonstrated that future SysML models can be used in conjunction with the HSF Translator Plugin to create a functional HSF system input script

    Integration of Utility Engineering, Coordination, and Highway Design

    State transportation agencies (STAs) strive to deliver highway projects on time and on budget. Utility relocations are frequently cited as a primary reason for delays. This report describes a new approach for enhancing the alignment of utility coordination and design. Researchers crafted this new approach based on the findings of a literature review, an evaluation of how utility coordination milestones and project development milestones are currently aligned at the Kentucky Transportation Cabinet (KYTC), and the experiences of other STAs. KYTC should use this guidance to facilitate implementation of the new approach and an associated Utility Coordination Training and Certification Program. All personnel engaged in project design and delivery can benefit from the proposed guidance (e.g., district utility coordinators, consultant utility coordinators, project designers, project managers, surveyors, right-of-way staff, construction staff, central office utility coordinators, etc.). This guidance document also includes suggestions for identifying, managing, and mitigating, utility-related risks using Utility Conflict Management (UCM), provides information on the use of Subsurface Utility Engineering (SUE), and offers recommendations for managing consultant-led utility coordination

    Model Based Systems Engineering for a Venture Class Launch Facility

    Get PDF
    A study of Model-Based Systems Engineering (MBSE) applied to a small-lift launch facility is presented. The research uses Systems Modeling Language (SysML) products and functional diagrams to document the structure, controls, electrical power, hydraulic, safety mechanisms, software, and fluid ground systems on a launch pad. The research is motivated by the need to design complex systems with an unambiguous understanding that improves communication, quality, productivity, and reduces risk. A model is developed following the ISO/IEC-15288 technical process framework. The stakeholder requirements are defined and analyzed to provide traceability to individual systems and subsystems. An architectural design is realized and implemented by generating engineering artifacts such as Piping and Instrumentation drawings (P&ID) and a hydraulic circuit diagram. The architecture is verified and validated by performing engineering trade studies focused on the fuel and pneumatic systems

    Investigating the design workflow for designing a component for Additive Manufacturing: A case study of designing a Jet engine combustion chamber component for AM

    Get PDF
    The increasing integration of Additive Manufacturing (AM) in the Product Development and production phase has brought a need for developing a new design for manufacturing methodology which is distinct to AM. Commonly known as Design for Additive Manufacturing (DfAM), it aims to take complete advantage of the unique capabilities of AM by developing rules, guidelines, and design methodologies. The existing studies on DfAM do not address practical problems faced during the design stage which leads to dilemmas and uncertainties in decision making concerning the design elements. Therefore, a workflow for implementing the methodologies of DfAM is important. To solve this problem, this thesis develops and documents the workflow for modeling lattice structures and minimal structures using the best tools available. In addition to this, the study analyzes the workflow developed with the help of a case study. In this case study, a component is developed for heat management which makes the use of heat transfer between solid and fluid. The design process in the case study is developed with the integration of Design for Six Sigma methodology. The outcomes are documented, and best practices from the study are reported

    In response to the Cooperative Agreement, Lockheed Martin Skunk Works has compiled an Annual Performance Report of the X-33/RLV Program. This report consists of individual reports from all industry team members, as well as NASA team centers. The first milestone was hand delivered to NASA MSFC. The second year has been one of significant accomplishment in which team members have demonstrated their ability to meet vital benchmarks while continuing on the technical adventure of the 20th century

    D7.5 FIRST consolidated project results

    Get PDF
    The FIRST project commenced in January 2017 and concluded in December 2022, including a 24-month suspension period due to the COVID-19 pandemic. Throughout the project, we successfully delivered seven technical reports, conducted three workshops on Key Enabling Technologies for Digital Factories in conjunction with CAiSE (in 2019, 2020, and 2022), produced a number of PhD theses, and published over 56 papers (and numbers of summitted journal papers). The purpose of this deliverable is to provide an updated account of the findings from our previous deliverables and publications. It involves compiling the original deliverables with necessary revisions to accurately reflect the final scientific outcomes of the project
