Abstract This paper presents high-fidelity multidisciplinary maneuver simulations of the new research aircraft Dassault Falcon 2000LX ISTAR of the German Aerospace Center (DLR). These simulations are computed using the multidisciplinary process chains FSAerOpt and UltraFLoads for the DLR project HighFly (high-speed inflight validation). The goal of this project is the validation of simulation models for virtual flight testing with data measured on the Falcon 2000LX ISTAR. The paper describes the individual numerical models and analyses of ISTAR: geometry (CAD), aerodynamics (CFD), control surface deflection in CFD, structure (CSM), aircraft mass distribution, and engine. It also gives a short overview of some UltraFLoads simulation processes, such as CFD-CSM coupling, trim analysis, and dynamic maneuver simulation. After that, the simulation results such as steady-state CFD-CSM coupled simulation of different trimmed horizontal flights and simulation of different dynamic maneuvers (bank-to-bank and pull-up and push-down maneuver) are presented. The first comparisons of the numerical simulations with the experimental data are also shown.
