STARS Finite Element Multidisciplinary Analysis Computer Program

Armstrong Flight Research Center, Edwards, California An efficient, cost-effective, and unique computer program has been developed that analyzes a variety of practical engineering problems. STructural Analysis Routines (STARS) is a fully integrated, multidisciplinary, finite element-based, graphic-oriented analysis tool that combines individual modules to solve complex engineering problems. The range of applications includes structural analysis, heat transfer, linear aerodynamics, and computational fluid dynamics (CFD), as well as coupled linear and CFD-based aeroelastic, aeroacoustics, aerothermoelastic-acoustics, and aeroservoelastic analysis. Because of the tool’s highly integrated nature, it has broad application across many engineering disciplines.

Hazards Analysis Management Tool

Goddard Space Flight Center, Greenbelt, Maryland The Hazard Analysis Management Tool (HAMT) is comprised of a database and user interface that manages hazard analysis information, manages hazard verifications, and manages relationships between hazard attributes and project elements. The tool offers numerous benefits including the ability for multiple users to simultaneously update information, auto-generation of hazard reports, improved data consistency, ability to quickly obtain up-to-date status reports, and the ability to execute complex queries on the hazard information. This tool does not provide a mechanism for the identification of hazards. The tool requires minimal IT overhead and is easily tailored for specific projects and/or user groups. This tool was developed as a support capability, and testing was limited to the operational environment in which it was initially deployed.

Developing Web and Mobile Applications Integrated with Systems Utilizing the Object Management Group’s Data Distribution Service

DDS-enabled applications range from human-computer interaction to data recording and retrieval. John F. Kennedy Space Center, Florida Several software application development tools exist that enable the rapid development of Web applications. Among other things, Web applications greatly enhance the human-computer interaction (HCI) required by many systems, while simplifying the problem of deploying applications to customers. Capitalizing on the new features provided by these tools could prove to be a boon to mission and project teams.

Synthetic Imaging Maneuver Optimization — SIMO

Goddard Space Flight Center, Greenbelt, Maryland Space-based interferometry missions have the potential to revolutionize imaging and astrometry, providing observations of unprecedented accuracy. Realizing the full potential of these interferometers poses several significant technological challenges. These include the efficient maneuvering of multiple collectors to various baselines to make the requisite observations; regulating the path-length of science light from the collecting telescopes to the combining instrument with nanometer accuracy, despite the presence of vibration induced by internal and external disturbance sources; and demonstrating through hardware-in-the-loop simulation that the numerous spacecraft (SC) subsystems can be coordinated to perform such challenging observations in a precise, efficient, and robust manner.

Overcome Challenges of Your Highly Constrained PCB Designs

Layout constraints are an essential part of a PCB design. As the technology in modern electronic devices has become more complex (e.g. increasing speed, decreasing rise time and supply voltage values), signal integrity issues have become a primary concern. For many designs, this means a large percentage of nets require PCB layout constraints to meet signal integrity requirements. This brings two major challenges: creating a proper set of layout constraints for your design and applying those constraints during the PCB layout design process. This paper shows how to address the challenges of highly constrained designs.

Removing the Gap Between ECAD and MCAD Design

For ECAD and MCAD to collaborate in “real-time” a direct method of communication that facilitates a shared flow of data back and forth between design teams is required. This flow must support “what-if” scenarios of design baselines and change proposals along with the ability to counter-propose changes. Once design agreements are made, the flow must also dynamically update the design databases. This unique ECAD-MCAD (EDMD) collaborative environment has not been available until now. This desktop PCB design provides a real-time integrated ECAD-MCAD collaboration environment that enables Electrical and Mechanical design teams to work together throughout the entire design process.
