NASA’s Marshall Space Flight Center has developed a unique apparatus ideal for use in nondestructive testing (NDT) of hermetic seals of containers or instrumentation. The device is capable of detecting both large and small leaks and can be calibrated to characterize the...

Traditional methods of flight flutter testing analyze system parameters such as damping levels that vary with flight conditions to monitor aircraft stability. In the past, the actual flight envelope developed for aircraft operation was essentially determined only by flight testing. The edges of...

Typically, mechanical test data has been reviewed and processed using a combination of Excel, PDF Viewer, MATLAB, and other tools. TestEVAL provides a central tool for all these tools, and enhances their capability. Having been developed in Python, it is expendable and portable. It uses no...

High-resolution submillimeter-wave spectroscopy is based on the heterodyne principle, where the incident signal is down-converted to a low intermediate frequency (IF) by nonlinear mixing with a local oscillator (LO) signal. The IF difference...

NASA has developed a novel hybrid supercapacitor system utilizing vertical graphene as an electrode material grown directly on collector metals using a plasma enhanced chemical vapor de - position. Supercapacitors are an alternative to batteries for energy storage, offering high power density and...

NASA’s Marshall Space Flight Center (MSFC) has developed compact, reconfigurable electronic devices to drive and control avionics instruments. Typical avionics systems function through centralized power distribution units (PDUs), which have complex, expensive, and time-consuming design, development, test, and...
