Wind tunnel facilities

The wind tunnel facilities are used to study aerodynamic characteristics (aerodynamics) and flow phenomena of the air surrounding aircraft or spacecraft. Airflow around aircraft can be simulated in a wind tunnel, which generates actual airflow artificially around an airframe model installed within the wind tunnel. By measuring some properties such as aerodynamic forces and pressure distributions around the model air frame, the wind tunnel allow us to grasp air behavior accurately.

JAXA Wind Tunnel Technology Center operates and manages wind tunnels of various sizes and types, which is one of the largest wind tunnel facilities in Japan, providing diverse test conditions with a wide range of velocities from low speed to hypersonic, or simulating severe re-entry environments with particular air-flow.
