Vertical Wind Tunnel

About Vertical Wind Tunnel

Marketing Overview

The Vertical Wind Tunnel is an advanced aerodynamic testing system designed to generate controlled upward airflow, enabling free-flight, spin, and stability testing of models. Unlike conventional horizontal wind tunnels, this configuration allows objects to be suspended or freely moving within the test section, closely simulating real flight behaviors such as stall, spin, and recovery.

Widely used in aerospace research, defense applications, and training environments, vertical wind tunnels provide a unique platform for studying dynamic stability, parachute systems, and human flight simulation. With precise airflow control and low-noise operation, they deliver high-fidelity experimental data in a controlled environment.
