AbstractThis SBIR Phase I project proposes to use overset grid HRLES (Hybrid RANS/LES) approach to simulate helicopter shipboard operations. After obtaining the computational results at a set of training points with this robust but computationally intensive approach, the principal basis functions of the solutions will be extracted from the numerical results with the POD (Proper Orthogonal Decomposition) technique. Instead of using the more popular Galerkin projections, D&P LLC proposes to use the RSM (Response Surface Methodology)/NN (Neural Networks) approach to further construct a robust reduced-order model of rotor induced flow with shipboard interactions for use in a real-time simulation. The capabilities and limitations of these methods for real-time modeling of rotor induced flow with shipboard interactions will be demonstrated through a feasibility study.
