Lattice-Boltzmann Real-Time Dynamic Interface Simulation Model

The Lattice-Boltzmann Real-time Dynamic Interface (LBRDI) project is a collaborative STTR research effort between Combustion Research and Flow Technology, Inc. (CRAFT Tech) and Georgia Tech that seeks to develop and evaluate Lattice-Boltzmann based CFD models (LBM) to predict the coupled rotor inflow when an aircraft is immersed in the ship airwake and is in close proximity to the ship surfaces. The research and development goals for this effort are 1) Develop LBM simulation models for tiltrotors that can accurately predict the coupled ship/aircraft aerodynamics and performance for full tiltrotor configurations in a real-time simulation environment; 2) assess the accuracy of the LBM simulation models by comparing to high-fidelity Navier-Stokes CFD data, comparing to Navy-provided flight test and experimental data, and generating verification and validation (V&V) experimental test data; and 3) integrate the LBM simulation models with the existing Manned Flight Simulator CASTLE environment at NAVAIR, Patuxent River.
