Numerical simulation model

The chapter presents the necessary steps in setting up a numerical simulation model of the ACFA 2020 blended wing body design. After a short introduction, a section on structural modeling presents the design steps from basic geometry, material properties, and load cases to structural concepts, nonstructural masses, and a mass estimation of the resulting structural model. The adaptations of an existing model from the NACRE project are also explained there. The next section focuses on aerodynamic modeling, where numerical methodsare explained and the respective results for steady and unsteady aerodynamics simulations are presented. The chapter is concluded by a section on integrated flight dynamic and aeroelastic modeling where the integration of all previous steps into a state-space model of the aircraft is presented.
