The Synergy of Engineering

At the Hannover Messe trade fair in Germany, Eplan Software & Service, with its affiliate company Cideon, introduced Syngineer, an innovative communication and information platform that integrates mechanical engineering, software engineering, and controls engineering through one mechatronic structure. Eplan, a sister company of Rittal Corporation in the Friedhelm Loh Group, offers Syngineer as a solution for simplifying synchronization across all three disciplines, accelerating design engineering and development.

Distributed, Fast, Intelligent Infrastructure Health Monitoring System

Improve operation and reduce maintenance costs with intelligent systems. Stennis Space Center, Mississippi NASA needed an innovative solution to conduct system assessments of frameworks and to characterize subsystems of interest. This tool would be required to determine anomalies; examine their causes (root-cause analysis); make predictive statements (prognostics); provide intelligent health monitoring with incremental knowledge for working with unknown scenarios; and provide maintenance support for a complex collection of systems, subsystems, and elements in rocket engine test platforms.

Net Radiation and Evapotranspiration (Rn/ET) Download Product Tools and Interfaces

NASA’s Jet Propulsion Laboratory, Pasadena, California This toolset automates downloads of global, multi-year Moderate Resolution Imaging Spectroradiometer (MODIS) and related data necessary for performing net radiation and evapotranspiration (Rn/ET) modeling, and provides an application programming interface (API) for simple and reliable access of these data from Python or MATLAB applications. Several useful utilities for validating and curating/indexing the downloaded data are also included.

Software Tools for Fault Management Technologies

Marshall Space Flight Center, Alabama Several key areas of improvement in effect design, development, verification, and validation of fault management processes have been identified in NASA’s Fault Management Handbook. The majority of these guidelines are focused on making the modeling tools more user friendly and reducing the modeling cost and time, as well as enhancing the analytic capabilities.

Tool to Analyze a Leaking Source of Saturated Ammonia

Lyndon B. Johnson Space Center, Houston, Texas Containers of ammonia are used to supply cooling to different modules of the International Space Station. Each container has an attachment piece used to extract the ammonia. The attachment piece may allow ammonia to exit when not connected, and may also allow ammonia to exit to an outside area even when connected. The ammonia that has exited the container may accumulate in different compartments of the spacecraft. The ammonia is not desirable when accumulated in a compartment with a certain concentration.

Mixed-Integer Convex Programming Algorithm for Constrained Attitude Guidance

NASA’s Jet Propulsion Laboratory, Pasadena, California A general problem in spaceflight since its beginning is attitude guidance: how to turn a spacecraft — also called a slew — so as to point science instruments at their targets. The slew must be done while avoiding pointing sensitive science instruments (e.g., a camera) and attitude sensors (e.g., a star tracker) at bright objects in the sky (e.g., the Sun or the Moon).
