Rotorcraft/UAV Modeling Using Advanced Simulation Tools
Thursday, March 17, 2016

Recent advances in automated mesh generation, the availability of high-fidelity and fully-coupled physics, and increased computational power are necessary and enabling factors for CFD-based design of next generation rotorcraft systems.

Accurate estimation of hover and performance parameters early in the design stage of vertical take-off and landing (VTOL) systems results in better component design and an overall reduction in the design iterations. Engineering simulation is well suited for studying complete configurations of VTOL systems such as helicopters, drones and UAVs.

In this webcast the CAD-to-mesh process, physics and efficient meshing capabilities suitable for studying complete rotorcraft configurations will be presented. Rotor performance prediction methods available in engineering simulation, ranging from virtual blade model to high-fidelity, transient overset mesh computations will be discussed.

This webcast includes a number of technical validation studies covering aerodynamic interaction of rotor/fuselage, hover performance estimation and component-wise hub drag reduction studies.
