“…A relational database management system Sparta DB has been developed and integrated with DOTNET framework for web accessibility as shown in Figure 8. RDBMS allows data of existing planetary design to be spread out in different tables like aerothermal, geometry, materials, and so forth to be linked via a column, for example, flight vehicle [7].…”

“…The DOTNET Web application retrieves the data from the flight vehicle database and populates the browser with all the flight vehicles atmospheric entry specific to the planet. Each flight vehicle contains aerothermal, geometry, and TPS information from the database and is displayed in the web browser [7]. Clicking on a specific flight vehicle launches the GUI with all the aerothermal data retrieved from the database and populated in the GUI as shown in Figure 12.…”

This publication presents the architecture integration and implementation of various modules in Sparta framework. Sparta is a trajectory engine that is hooked to an Online Analytical Processing (OLAP) database for Multi-dimensional analysis capability. OLAP is an Online Analytical Processing database that has a comprehensive list of atmospheric entry probes and their vehicle dimensions, trajectory data, aero-thermal data and material properties like Carbon, Silicon and Carbon-Phenolic based Ablators. An approach is presented for dynamic TPS design. OLAP has the capability to run in one simulation several different trajectory conditions and the output is stored back into the database and can be queried for appropriate trajectory type. An OLAP simulation can be setup by spawning individual threads to run for three types of trajectory: Nominal, Undershoot and Overshoot trajectory. Sparta graphical user interface provides capabilities to choose from a list of flight vehicles or enter trajectory and geometry information of a vehicle in design. DOTNET framework acts as a middleware layer between the trajectory engine and the user interface and also between the web user interface and the OLAP database. Trajectory output can be obtained in TecPlot format, Excel output or in a KML (Keyhole Markup Language) format. Framework employs an API (application programming interface) to convert trajectory data into a formatted KML file that is used by Google Earth for simulating Earth-entry fly-by visualizations.
