Method and Software Tool for Evaluation and Automated Generation of Space Habitat Interior Layouts

The software can help design space habitats, submarines, ships, aircraft, recreational vehicles, and small residences.NASA has developed a new software tool for optimizing interior layout designs of highly constrained, highly integrated, and/or confined spaces, such as space habitats. This tool will automatically generate or evaluate interior layout options while taking into account multiple end-user objectives. Development and evaluation of interior layouts are often ignored during conceptual design because of the subjectivity and long times required using current evaluation methods (e.g., human-in-the-loop mockup tests and in-depth CAD evaluations). The NASA tool will allow for early, more objective assessment that will prevent expensive design changes, which can increase vehicle mass and compromise functionality.

Airborne Wind Profiling Algorithm for Doppler Wind Lidar

This novel method enables accurate, real-time parameter estimation in noisy environments.NASA’s Langley Research Center has developed an algorithm, Airborne Wind Profiling Algorithm for Doppler Wind Lidar (APOLO), that offers highly accurate, real-time measurement of wind parameters (i.e., direction and speed) by airborne wind lidar sensors. APOLO enables the extraction of accurate wind speed and direction from noisy flight environments, and provides correction for instrument installation biases. The algorithm has been incorporated into a supporting software package that displays accurate airborne Doppler wind lidar data, and offers several data post-processing and display functionalities. The offset compensation and parameter extraction technology could be used in a variety of applications where the motion and orientation of a lidar sensor may result in data inaccuracy. NASA is seeking licensees that may benefit from integration of the compensation algorithm and data post-processing software into existing or developing systems.

NETMARK Fast Search

Applications include enterprise knowledge management, and document and content management systems.The problem that motivated this work was one of analyzing hundreds of thousands of records of historical problem failure reports (aka, problem reports and corrective actions — PRACA) for improved mission safety. Whenever there is an anomaly in mission design or operations, the anomaly gets entered into a problem failure reporting database for tracking purposes. The objective of the research was to make this data queryable and analyzable using the NETMARK XML database.

Key Considerations for Powertrain HIL Test

Safety, availability, and cost considerations can make performing thorough tests of embedded control devices using the complete system impractical. Hardware-in-the-loop (HIL) simulation is a real-time test technique used to test these devices more efficiently. During HIL test, the physical system that interfaces to an embedded control device is simulated on real-time hardware, and the outputs of the simulator mimic the actual output of the physical system. The embedded controller “thinks” it is in a real system. HIL simulation meticulously tests embedded control devices in a virtual environment before proceeding to real-world tests of the complete system. This application note covers recommended best practices for powertrain HIL testing.
