CFD for Mechanical Design Engineers - “A Paradigm Shift for Better Design”

There is demonstrated, real value in using CFD to analyze products earlier in the product development lifecycle than has been possible under the common scenario of reserving this important analysis regimen for CFD specialists.

Solving the System-Level Thermal Management Challenges of LEDs

As thermal management continues to be critical to LED performance, thermal simulation is playing an increasingly important role in LED system design. New generation CAD-embedded thermal and fluid simulation software makes it possible for LED systems designers to diagnose thermal problems, evaluate a large number of design alternatives quickly, and iterate rapidly to an optimal solution. Another bonus? Having a deep understanding of the computational aspects of fluid dynamics is no longer a requirement...

Convex Hull-Based Plume and Anomaly Detection

A number of deep space missions have imaged plumes at Io, Enceladus, and other smaller bodies. These phenomena provide valuable information regarding these bodies. To date, this imagery has been captured fortuitously. The ability to utilize onboard processing to conduct campaigns capturing large numbers of images and to detect when a plume event is occurring would open up new mission paradigms. Extended temporal campaigns could provide comprehensive detail on these events’ frequency and character.

Software for Non-Contact Measurement of an Individual’s Heart Rate Using a Common Camera

A software application detects the heart rate of an individual by using a real-time video stream from a common camera connected to their computer. This involves no contact between the user and the camera, or calibration between individual users. NASA’s OpenMDAO framework was used to implement and coordinate the necessary data acquisition and signal processing functions.

Software Suite to Support In-Flight Characterization of Remote Sensing Systems

A characterization software suite was developed to facilitate NASA’s in-flight characterization of commercial remote sensing systems. Characterization of aerial and satellite systems requires knowledge of ground characteristics, or ground truth. This information is typically obtained with instruments taking measurements prior to or during a remote sensing system overpass. Acquired ground-truth data, which can consist of hundreds of measurements with different data formats, must be processed before it can be used in the characterization. Accurate in-flight characterization of remote sensing systems relies on multiple field data acquisitions that are efficiently processed, with minimal error.

Spacecraft Trajectory Analysis and Mission Planning Simulation (STAMPS) Software

STAMPS simulates either three- or six-degree-of-freedom cases for all spacecraft flight phases using translated HAL flight software or generic GN&C models. Single or multiple trajectories can be simulated for use in optimization and dispersion analysis. It includes math models for the vehicle and environment, and currently features a “C” version of shuttle onboard flight software. The STAMPS software is used for mission planning and analysis within ascent/descent, rendezvous, proximity operations, and navigation flight design areas.

Cross Support Transfer Service (CSTS) Framework Library

Within the Consultative Committee for Space Data Systems (CCSDS), there is an effort to standardize data transfer between ground stations and control centers. CCSDS plans to publish a collection of transfer services that will each address the transfer of a particular type of data (e.g., tracking data). These services will be called Cross Support Transfer Services (CSTSs). All of these services will make use of a common foundation that is called the CSTS Framework. This library implements the User side of the CSTS Framework. “User side” means that the library performs the role that is typically expected of the control center.
