This tool sizes solar power systems utilizing batteries, fuel cells and solar cells and calculates the mass, power and potential volume requirements of the system. It will provide a rough estimate of the sizes of the cells, the tank volumes and masses for the fuel cells and determining decay rates...

NASA Langley Research Center has developed a test station capable of in-situ testing of material deposition and layer adhesion in an extrusion additive manufacturing process. The technology addresses the problem of monitoring part quality during the 3D printing process. It includes methods that...

The new version (3.0) suite of the 3DGRAPE/AL software advances the state-of-the art in structured volume grid generation through the implementation of a new matching point block-to block boundary condition on adjacent faces of two blocks that no other volume grid generator has. This new version...

Nonlinear six degree-of-freedom simulations for a variety of aircraft were created using MATLAB. Data for aircraft geometry, aerodynamic characteristics, mass / inertia properties, and engine characteristics were obtained from open literature publications documenting wind tunnel experiments and...

NASA's Langley Research Center has developed a portable device to simulate low-velocity impacts on a material or structure. As composite materials are highly susceptible to damage caused by low-velocity impact, they must be designed and evaluated for structural integrity after these types of...

The innovation is a computer program which can be used to design two-dimensional or axisymmetric nozzles having uniform or non-uniform (Mach number and/or flow angle) supersonic inflow. If possible, the computer program generates a nozzle contour which produces supersonic, shock-free, uniform flow...

The software will load in image collections from Google Earth Engine from different sensors (Landsat 5, 7, and 8, Sentinel 2a, 2b) and the code will identify pixels meeting certain criteria as snow using two snow indices (Normalized Difference Snow Index (NDSI) and the Saito S3 Snow Index. Then the...

abaverify is a collection of Python scripts that is used for testing and verifying the behavior of user subroutines for the commercial finite element code Abaqus.

This innovation is a thermal processing methodology for retaining the fine-grained structure in aluminum alloys subjected to solid state welding and subsequent forming processes.

The Acoustic Propagation and Emulation Toolset (APET) is a framework code uniting several acoustic methodologies for the propagation and measurement of source noise audibility at farfield observers, accounting for the effects of the atmosphere, weather, terrain, and spherical spreading. Currently,...
