Dynamic Structural Scaling Concept for a Delta Wing Wind Tunnel Configuration Using Additive Manufacturing

Considering aeroelastic effects plays a vital role in the aircraft design process. The construction of elastic wind tunnel models is critical element investigation occurring phenomena. However, structural scaling between full-scale and reduced-scale configurations complex manufacturing task usually avoided testing. This work proposes numerical approach for dynamic technique, which applied to fictive delta wing configuration. methodology designed optimise layout with an integrated rib spar structure meet behaviour realistic equivalent. For modelling structure, beam shell utilised. laws relevant quantities procedures are described. Computational fluid dynamics (CFD) calculations performed by solving Reynolds-averaged Navier–Stokes (RANS) equations assumption rigid down-scaled wing. These used verify aerodynamic assumptions, procedure model. Global coefficients evaluated variety angles attack. local flow phenomena scaled model compared more detail medium high angle pressure coefficient distribution shows proper accordance To results optimisation, high-fidelity using ELFINI FEM solver. Therefore, all components modelled 2D elements. reduced eigenfrequencies according modes show level similarity. A static deformation grids applying loads from CFD simulations. that deviation nondimensional negligible. Consequently, proves be valuable tool conceptual designing aeroelastically considering 3D-printed material.
