Turkish Aerospace Industries (TUSAŞ) has officially initiated test operations in its newly commissioned Subsonic Wind Tunnel, which is the second-largest facility of its kind in Europe. The initial official tests were successfully completed, signifying a substantial advancement in Türkiye’s aerospace research and development capabilities.
This facility is among the top aerospace test facilities in Europe.
According to TUSAŞ, the tunnel has distinguished itself among Europe’s top aerospace wind tunnel facilities due to its advanced design, large scale, and ability to reach high subsonic speeds. The tunnel’s advanced infrastructure facilitates a wide range of aerodynamic and aeroacoustic experiments.
This product features a versatile closed-loop design with multiple test sections.
The wind tunnel is constructed as a closed-loop system and comprises three distinct test sections, each designed to meet specific testing requirements:
The dimensions of the small test section are 4.9 meters by 3.7 meters. This model allows testing of smaller models at speeds up to Mach 0.55.
Large Test Section (6.4 m x 4.8 m): It is designed to support the testing of larger models up to Mach 0.4.
Open Test Section: This feature allows tests up to Mach 0.3 while eliminating the closed-wall effect, ensuring accurate aeroacoustic assessments.
The first test of the KAAN national combat aircraft model is now underway
The commissioning phase commenced in October 2024, beginning with the Small Test Section. During this stage, TUSAŞ successfully validated all infrastructure systems, including engine controls, automation software, flow temperature regulation, and general tunnel operations.
Once the system reached operational maturity, the first series of tests was initiated using a 1/9 scale instrumented model of the KAAN National Combat Aircraft. In April 2025, the integration of sensors and the placement of models were finalized, followed by shake-down tests to assess the system’s readiness.
On May 2, 2025, TUSAŞ officially initiated full-scale testing in the Subsonic Wind Tunnel, establishing the facility as a vital component in the development of Turkey’s next-generation fighter aircraft.
