N2 - This paper presents unsteady aeroelastic simulation of a 3D-Printed propeller blade designed for High-Altitude Pseudo-Satellites by using Fluid-Structure Interaction FSI. Aerodynamic simulations are carried out in ANSYS Fluent considering an altitude of 16 km, and the spring-based smoothing method is used for updating the mesh during the coupling. Tough PLA 3D-printed material is used to model the blade structure with a composite layer covering the external surface of the blade. In order to model the 3D-printed material, tensile and bending experimental tests have been performed and validated numerically using ANSYS Mechanical. The numerical model, that is derived from the experimental tensile results, is then used to perform tensile test simulations on substitute and twisted blades to compare their results with the experimental results of 3D-printed substitute and twisted blades for validation. The tip leading edge deflection and the blade stresses are compared between unsteady FSI and unsteady structural response, while the aerodynamic performance are compared between unsteady FSI and steady FSI.
