Abstract:

The goal of this project is to integrate novel numerical modeling and computer hardware approaches to compute the non-linear aerodynamic coupling between the ship and aircraft in such a way that execution times are at real-time speeds, allowing for pilot-in-the-loop CFD to be integrated in the piloted flight simulation environment. To achieve the speed gains required, three areas will be targeted for implementation into the CFD simulation framework 1 numerical algorithms, 2 novel domain boundaries, and 3 Graphical Processing Unit GPU hardware. A framework will be established to link the CFD with real time simulations. A building block approach will be employed to first demonstrate non-real time integration of the CFD simulation framework with helicopter flight dynamic models, then real time execution for a minimum fidelity airwakeaircraft simulation, then build to higher fidelity real time simulations. During this reporting period, structured simulations for the example LHD airwake were initiated using the improved incompressible formulation implemented in the CRAFT CFD solver that was presented in the previous report. The goal of these simulations is to provide a verification of the structured airwake solution against standard practice unstructured results for the ship platform of interest LHD.
