Abstract. This paper presents a validation of high-fidelity aeroelastic maneuver simulations using experimental data of the DLR Falcon 2000 ISTAR aircraft in a clean cruise configuration from the HighFly MaGE flight test campaign. The dynamic open-loop maneuver simulations of the flexible free-flying aircraft are achieved with the DLR multidisciplinary process chain UltraFLoads, which can combine a flight dynamics model with a CFD flow solver (URANS with the DLR TAU-Code) and an unsteady structural modal analysis computed from the FE NASTRAN model. Pull-up and push-down and bank-to-bank maneuver simulations of different flight points are investigated (subsonic and transonic). The static pressure distributions on three chordwise wing sections and global flight dynamic quantities are compared with experimental data. Three pressure distributions on the right wing of the ISTAR aircraft were dynamically measured during the MaGE flight campaign using pMEMS sensors (Micro Electro Mechanical System).
