Design and Analysis Software Ensures Safety of Launch Vehicle Structures

NX‘and Teamcenter® software Siemens PLM Software Plano, TX 800-498-5351 www.siemens.com/plm One of ATK Aerospace Group’s current projects involves the Space Launch System (SLS). The SLS is the largest rocket ever built for entirely new human exploration missions beyond Earth’s orbit, and will take astronauts farther into space, eventually including missions to Mars. Its first flight is scheduled for 2017.

Brainwave Monitoring Software Helps Distracted Minds

Software designed to help pilots stay attentive now improves workplace, school, and sports performance. Imagine moving an object using only your mind. Software company Unique Logic’s Time on Task exercise makes that possible, at least on a computer screen. The game is one of the company’s Play Attention educational line, and is designed to teach people how to sustain their attention in order to complete tasks. It involves getting a forklift operator to transport a stack of crates from the ground onto the back of a truck. Instead of using a remote control to dictate the action, you use your concentration — measured by sensors that detect patterns of brainwave activity — to induce the operator to complete the job.

Enhanced Project Management Tool

The system monitors the progress of multiple activities and generates management reports at different detail levels. Ames Research Center, Moffett Field, California A complex project having many tasks and sub-tasks, many phases, and many workers will often require an evaluation of completion of the tasks and sub-tasks at several times during the project’s duration. Initially and throughout the duration, suitability of the technical and inter-personal characteristics of the workers, managers, and teams should also be evaluated. What is needed is a system that allows a user to specify a type of report, to specify one or more classes of information within this type of report, to specify a time interval, to specify one or more projects, and to receive the status and/or comparisons of performance for the specified projects.

Advanced Navigation Strategies for Asteroid Sample Return Missions

Goddard Space Flight Center, Greenbelt, Maryland Sample-return missions to primitive solar system bodies (asteroids, comets, and planetary satellites) can provide a wealth of scientific information and insight into the composition and origins of the solar system. Recent interest in primitive body missions has been driven by the possibility of human near-Earth object missions, Earth conjunction analysis, and scientific discovery. Precision navigation to acquire a sample from a primitive solar system body and return it to Earth presents unique challenges beyond traditional Earth-based and interplanetary missions.

Half-Cycle Crack Growth

Armstrong Flight Research Center, Edwards, California Half-Cycle Crack Growth software offers a reliable method for calculating theoretical fatigue crack growths that could lead to catastrophic structural component failures. The program builds upon and integrates Armstrong’s proven half-cycle and closed-form aging theories, and considers every half-cycle of loading spectra for specific structural components. The program works by reading test data files and determining maximum and minimum loads of each half-cycle of random loading spectra in order to calculate theoretical crack growth. The innovation is an improvement on traditional prediction software (and in particular, on visual inspections) because it considers mini-amplitude stress loading and half-cycles based on the duty cycle of a particular component or structure. Developed to calculate the number of operational life flights for B-52B pylon hooks at Armstrong testing facilities, the program and underlying theories can be applied to estimate the service life of any critical structural component, making it suitable for use in other industries, especially for construction and petrochemical firms.
