Trapped Radiation Models - Uncertainties For Spacecraft Design
The focus of Trapped Radiation Models software development effort was to help spacecraft and payload designers to account for uncertainties in predictive models of the Earth's trapped radiation environment. A tool was needed for more accurately determining radiation requirements and risks -- essential elements for producing less expensive, more reliable spacecraft.

Python Interface to Dual-Pol Radar Algorithms (DualPol)
This is an object-oriented Python module that facilitates precipitation retrievals (e.g., hydrometeor type, precipitation rate, precipitation mass, particle size distribution information) from polarimetric radar data. It leverages existing open source radar software packages to perform all-in-one retrievals that are then easily visualized or saved using existing software.

VLOADS V1.4 Launch Vehicle Loads Analysis For Preliminary Design
The VLOADS program calculates launch vehicles' in-flight structural loads for preliminary design. The program may also be used to calculate structural loads for upper stages and planetary transfer vehicles. Launch vehicle information and input data such as aerodynamic coefficients, mass properties, propellants, engine thrusts, and performance data are compiled and analyzed by VLOADS to produce distributed shear loads, bending moments, axial forces, and vehicle line loads as a function of X-station along the vehicle's length. Translational accelerations and interface loads, if the launch vehicle has booseters or wings, are also computed.

Comments Export/Management Tool
This tool is a collection of macros that work with Microsoft Word to export Word comments into a pre-formatted Excel spreadsheet, which is used to disposition comments during a document review and serves as an official record of the disposition of each comment. The tool includes the ability to add comments in real time and trigger an automatic update of the spreadsheet and the ability to instantly navigate from a row in the spreadsheet to the matching comment in the Word document (through the use of hyperlinks). This tool vastly improves the efficiency of electronic document reviews of acquisition documents.

Tool for Analysis of Surface Cracks (TASC)
Created using the commercial math analysis software MATLAB, TASC enables the easy computation of nonlinear J-integral solutions for surface-cracked plates in tension by accessing and interpolating between the 600 nonlinear surface crack solutions documented in NASA/TP-2011-217480. The only required inputs to the program are the surface crack dimensions, plate cross-section dimensions, and material properties. TASC provides a convenient and easy-to-use interface for the solution set that allows a novice user to obtain a fast and reliable fracture toughness solution.
