Design of a Freely Rotating Wind Tunnel Test Bench for Measurements of Dynamic Coefficients [PDF]
56th 3AF International Conference on Applied Aerodynamics,
Association A{\'e}ronautique et Astronautique de France (3AF), Mar 2022,
Toulouse, France, 2023 The needs to improve performances of artillery projectiles require accurate aerodynamic investigation methods. The aerodynamic design of a projectile usually starts from numerical analyses, mostly including semiempirical methods and/or Computational Fluid Dynamics (CFD), up to experimental techniques composed of wind-tunnel measurements or free-flight ...

Aeroacoustic wind tunnel tests
, 2020 The global demand for renewable energy sources has led to an increase in development and installation of wind turbines. However, noise regulations on wind turbines near populated areas can restrict the installation of new wind turbines and limit the potential energy production. The main noise from wind turbines is aerodynamic and arises from turbulence
