Two very different wind tunnel developments caught our attention this week — one on the ground, one in the air.
1. Poland Upgrades Its Largest Wind Tunnel
Last week, Warsaw unveiled the modernized T-3 wind tunnel at the Łukasiewicz Institute of Aviation — now the largest facility of its kind in Poland and all of Central and Eastern Europe. The upgrade cost 105 million zlotys (over €24 million), funded through Poland’s National Recovery Plan.
What was modernized? Almost everything except the concrete structure. New linings, new measurement space, new instrumentation — all replaced with the latest technology available. The result, according to Institute Director Prof. Cezary Szczepański, is a "unique workshop for aerodynamic measurements" unlike any other.
The upgraded tunnel will support:
-
European Space Agency projects, including the EXAELIA experimental aircraft program
-
European Defence Fund projects, with 70% of the institute's research now defense-related (up from 12.5% in 2023)
-
Polish space programs, including the Bursztyn rocket and SPARK nanosatellite (planned for 2027 launch)
-
Small and medium enterprises in the drone and "new space" sectors
2. Starfighters Space Advances "Wind Tunnel in the Sky"
Meanwhile, on the other side of the Atlantic, Starfighters Space announced the next phase of its "Wind Tunnel in the Sky" — a reusable airborne platform that uses F-104 supersonic jets for real-atmosphere testing.
Key specs:
-
45-minute mission with up to 10 minutes of Mach 2+ test time
-
Compare that to traditional wind tunnel runs that last seconds
-
Exposes hardware to real-world conditions — weather variation, vibration, acceleration, dynamic pressure, temperature — things ground tunnels can't fully replicate
As Starfighters CEO Tim Franta put it: "While ground wind tunnels remain essential for aerospace research and development, airborne testing can expose hardware to combinations of weather variation, vibration, acceleration, dynamic pressure, temperature and operational conditions that cannot always be fully reproduced in a fixed facility."
The Bigger Picture
Two developments. Two different approaches. One theme.
Poland's T-3 represents the ground-based future — a modernized, powerful facility that keeps researchers at home instead of sending them abroad.
Starfighters' "Wind Tunnel in the Sky" represents the airborne future — taking testing off the ground and into real atmospheric conditions.
But both share the same goal: better understanding of aerodynamics.
What This Means for You
You don’t need a 5-meter test section or an F-104 supersonic jet to explore aerodynamics.
The same principles that drive these innovations — understanding how air flows around objects — are accessible at your desk. The CaptainRC 1:64 Desktop Wind Tunnel brings aerodynamic visualization to hobbyists, educators, and collectors:
-
Watch smoke trace airflow over your model cars
-
See how shape, wing profile, and angle of attack affect drag and lift
-
Understand what Poland and Starfighters are testing — just at a smaller scale
The CaptainRC Perspective
From Poland’s 5-meter diameter T-3 tunnel (capable of 100 m/s, or 360 km/h) to Starfighters’ Mach 2+ "sky tunnel" — the wind tunnel world is investing like never before.
Why? Because some things about airflow can only be seen, not simulated.
We believe the same. Whether you're testing a spacecraft, a supersonic fighter, or a 1:64 model, seeing airflow changes how you think about every aircraft you fly.
