A unique ultrasonic-based technique has been developed to measure temperature profiles in materials used in thermal protection systems (TPS). The technology requires measurements of the thermal expansion coefficient and the ultrasonic velocity for these materials as a function of temperature in...

This work involves development of aerogel to be used as a passive absorption media — effectively a concentrator of trace organics — that can be detected by optical techniques. Such a trace organic detection scheme is very different from all...

The Toughened Uni-piece Fibrous Reinforced Oxidation-Resistant Composite (TUFROC) allows for much more affordable and sustainable operations involving Space Launch Services and other systems that utilize Earth re-entry vehicles. TUFROC has an exposed surface design and...

M55J/RS-3C resin composite structures on the James Webb Space Telescope (JWST) sunshield will concurrently maintain loads and be exposed to temperature extremes throughout the life of the observatory. Increasing the glass transition temperature (Tg) is...

The control system in modern commercial aircraft engines is designed to operate the engine in a safe manner throughout its operating envelope. In order to utilize the existing safety margins more effectively, innovators at NASA’s Glenn Research Center have developed a modification to current min-max...

Innovators at NASA’s Armstrong Flight Research Center are experimenting with a new wing design that removes adverse yaw and dramatically increases aircraft efficiency by reducing drag. The technology has the potential to significantly increase...

The X-Plane Connect Toolbox is an open-source research tool used to interact with the commercial flight simulator software X-Plane. XPC allows users to control aircraft and receive real-time state information from aircraft simulated in X-Plane using functions written in C, C++, Java, MathWorks’ MATLAB, or...

In the current National Airspace System (NAS), there are many airports that are capacity-limited during the busiest parts of the day, and air traffic is expected to increase substantially in the future. NASA and the FAA are looking toward technologies that improve the capacity and efficiency of the...

Heterogeneous Spacecraft Networks (HSNs) are network environments in which spacecraft from different missions and institutions can communicate with each other at a low cost and with low impact on overall system resources. The technology of heterogeneous wireless networks has yet to be extended to space networks,...

The purpose of this invention is to provide a novel, low-loss, dual-band reflectarray element design that is transparent and low-loss across one frequency band (Ka-band in the initial application), and provides the phasing and beam collimation capability...

Geomagnetic storms drive geomagnetically induced currents (GICs) in high-voltage power transmission systems. GICs thus carry information about the near-space environment conditions. The U.S. high-voltage power transmission system was used as an extremely large antenna to...

NASA has developed a novel approach for producing sugars and sugar acids enriched with one of the two enantiomers of individual compounds. This approach can also be adapted for other compounds, such as amino acids. All objects, including chemical compounds, have mirror...

Innovators at NASA’s Glenn Research Center have developed a method for producing pure high-pressure oxygen via an electrochemical pumping process through a solid oxide electrolysis (SOE) cell stack. Glenn’s device can either concentrate the oxygen...

Solid-state nanopore-based analysis of nucleic acid polymers is revolutionary. No other technique can determine information content in single molecules of genetic material at speeds of 1 subunit per microsecond. Since individual molecules are counted, the output is intrinsically quantitative. The nanopore approach is more...

NASA’s Langley Research Center has developed a portfolio of technologies regarding clock synchronization in distributed systems. Distributed synchronous systems that need to provide globally coordinated operations require each component (node) in the system to be...

This software models the performance of a Fourier transform spectrometer (FTS). More specifically, it is able to add a number of noise/error sources to the interferogram and transform the errors back to the spectral domain.

This work extends the mesh generation capability of NASA’s Cart3D flow simulation software package to permit cell-by-cell mesh enrichment. Cart3D allows users to perform automated Computational Fluid Dynamics (CFD) analysis on a complex geometry. It includes utilities for...

Innovators at NASA’s Glenn Research Center have developed new sensors that can be integrated into thermal protection systems (TPS) to protect them from environmental damage. Radiation, shock, and ablation (erosion of the protective outer surface) combine to damage the TPS...

NASA’s Langley Research Center has extensively studied self-metallized polyimide films for aerospace applications. These thin films have shown promise not only as reflective coatings, but also conductive coatings. NASA believes that its technology may offer advantages to sensor companies, especially...

The present innovation, developed at NASA’s Goddard Space Flight Center, comprises several piezoresistor sensor configurations for sensing rotation or torque that are superior to those currently in use in microelectromechanical (MEMS) devices. These may be used for sensing rotation/torque or any other quantity that can be...

NASA has patented a unique chemical sensor array leveraging nano-structures for monitoring the concentration of chemical species or gas molecules that is not damaged when exposed to protons and other high-energy particles over time. The nanotechnology-enabled chemical sensor array uses single...
