Summary of Case 5 from Sixth Drag Prediction Workshop: Coupled Aerostructural Simulation

Abstract

A summary of participants’ results for the coupled aerostructural simulation test case from the Sixth AIAA Computational Fluid Dynamics Drag Prediction Workshop held in Washington, DC, 16–17 June 2016, is presented. The test case focuses on a static aeroelastic simulation of NASA’s Common Research Model civil transport aircraft in the wing/body configuration (i.e., without engines, pylons, and empennage). Flow conditions include the design point lift coefficient at cruise flight. Aeroelastic simulations are performed on the “medium” baseline grid, coupled to a computational structural analysis, using either an existing finite element model or modal data. Experimental validation data for this test case are available from a wind-tunnel test campaign performed at the European Transonic Wind Tunnel in Cologne, Germany.
