Web Application: Ground Hardware Management Tool

John F. Kennedy Space Center, Florida An integrated ground support equipment (GSE) tracking and management tool is designed for tracking and managing GSE data used in support of KSC/Ground Systems Development and Operations (GSDO) planning and launch campaigns. This software (the Ground Hardware Management Tool, GHMT) will be fully integrated with the Ground Operations Planning Database (GOPDb) to provide a complete ground operations planning solution.

Bird Vision System

This system is applicable to commercial airports and military airfields where the likelihood of bird strikes is high, and for environmental studies. John F. Kennedy Space Center, Florida About 2.5 seconds after the launch of STS-114, the first Return to Flight launch after the Columbia accident, a large bird struck the external tank and fell into the exhaust plume. While this particular bird strike did not threaten the vehicle because it did not strike the orbiter, it did raise awareness of the threat of avian fauna present at launch. In response to the avian threat, a Bird Radar system was developed to detect birds above the launch pad. Because of interference with launch systems, the radar system could not span closer than a few hundred feet above the pad. There was a gap region that would not be visible with the radar.

Fully Implicit Ablation and Thermal Analysis Program, Version 3 (FIAT v3)

The program is very stable and robust for application to both robotic and crewed vehicles entering a planetary atmosphere from space. Ames Research Center, Moffett Field, California FIAT v3 simulates one-dimensional thermal energy transport through a multilayer stack of thermal protection materials, bonding materials, metallic or composite structures, air gaps, and/or insulations. The outer surface encounters aerothermal heating from hypersonic flow, and the inner surface may have various boundary conditions such as assigned temperature history, insulated, or convective cooling. The heated outer surface can ablate, and materials can decompose (pyrolyze) in-depth.

CFD Utility Software Library

Ames Research Center, Moffett Field, California Originating as the Aerodynamics Division Software Library of the 1980s and -90s, this software is a collection of more than 100 software applications, many of them for manipulating the grids and flow solutions associated with computational fluid dynamics (CFD). Underlying these applications are about 30 libraries containing more than 1,200 subroutines, functions, or modules, mostly written in Fortran [90] with a small collection of C translations. Wherever possible, the software is generalized with reuse and portability in mind. These tools often operate on files in PLOT3D and/or Tecplot format, which represent de facto standards at many sites within academia, NASA, and industry. Utilities for treating unstructured data are also included along with a collection of programming tools for manipulating character data. Library names such as geomlib, interplib, optlib, and searchlib suggest the scope of numerics covered, while I/O packages such as tecplot_io, triangulation_io, and xyzq_io can ease development of new applications.

What is Wiring Synthesis?

Wiring synthesis is a transformative technology for vehicle wiring design. Using principles of Model Driven Systems Engineering (MDSE), wiring synthesis automatically generates detailed vehicle wiring design data from simpler, higher level inputs. Totally different from traditional wire routing, wiring synthesis addresses key domain problems such as high frequency design change, arduous configuration management, design quality and verification, and development cost and cycle time. Supported by ten years of software development, major automotive OEMs and suppliers in Europe, USA and Asia have now applied wiring synthesis technology with great success. As electrical complexity continues to grow, wiring synthesis will become the only practical way to design automotive electrical systems.

Optimizing Automotive Wiring Designs Using Engineering Design Automation

Currently, most methods for optimizing an Electrical Distribution System employ unsophisticated and manual spreadsheet tools. Any detailed feedback on critical metrics such as cost or weight typically relies on another organization and requires weeks or months. The resulting EDS is inevitably sub-optimized, not due to a lack of engineering ability, but rather the tools available. To ensure that the EDS design is optimized from the outset, the design environment itself must be enhanced. This paper will discuss the four key requirements for an EDA system along with the flow implications using examples from the Mentor Graphics Capital suite.

Technology To Speed Wire Harness New Product Introduction

The speed with which wire harness makers can bring new or changed designs into production is a key business differentiator. Up until now, the complex sequence of tasks necessary to accomplish such a feat was poorly supported by COTS software. A robust COTS solution from Mentor Graphics is now available. This paper focuses on a set of manufacturing disciplines and describes key “building blocks” which underpin Mentor’s robust software solution for harness wire manufacturers. The Mentor approach protects company IP, reduces manufacturing engineering costs, improves process quality, and provides early and accurate visibility of gross margins. More importantly, it removes critical path bottlenecks to new product introduction.
