Recent Advancements in the Helios Rotorcraft Simulation Code

Abstract

An overview of new capabilities recently included in the HPCMP CREATE TM -AV Helios high-delity rotorcraft simulation code is presented. These include a new implicit obody Cartesian solver to support both steady solutions and time-accurate RANS/DES in the wake, a new body hierarchy formulation to support coupled wing/rotor aeroelastics and maneuvering ight, a new strand-based near-body solver intended to support enhanced automation and accuracy, the inclusion of two new unstructured near-body solvers { FUN3D from NASA and kCFD from CREATE-AV Kestrel. New unsteady particle tracing and moving contour plane capability have been added to runtime-based in situ visualization. Example application of these capabilities are presented.
