Reduce Order Airwake Modeling for Aircraft/Ship Integration Modeling and Simulation

The objective of this STTR program is to develop a POD-based reduced order airwake modeling (ROAM) approach for efficiently and accurately representing the computed CFD airwake data, reducing the data storage and memory requirements by three orders of magnitude, and streamlining the integration of the airwake model with the flight simulation. The POD-based ROAM approach will be implemented in user-friendly software tools for processing the CFD data, creating the ROAM model, verifying the accuracy of the ROAM representation of the CFD data, and interfacing with the flight simulator. The goal of the program is thus two-fold: 1) develop a ROAM approach for streamlining and simplifying the data requirements of the airwake model while preserving the fidelity of turbulence characteristics important to the aircraft flight dynamics, and 2) develop airwake model integration software tools that will allow for general “plug-and-play” interfacing of the ROAM models with flight simulators. The proposed STTR research team for this program consists of Combustion Research and Flow Technology (CRAFT Tech) and the Applied Research Laboratories, The University of Texas at Austin (ARL:UT).
