Wind Tunnel
UAS wind tunnel is one of the largest and most modern open subsonic wind tunnels present in Italy. It represents a useful tool for UAS to analyze the aerodynamic characteristics within a wide speed range of different aircrafts thus permitting various flight condition simulations.There are two test chambers: one for high speed tests and one for low speed tests. The air flow is generated by 250 kW fan.
The UAS open circuit tunnel allows tests to be conducted even in the presence of combustion engines because the exhaust gases are expelled outside.

MODEL SUPPORT SYSTEM
In the wind tunnel there is a model support system, that can be easily moved from one test chamber to another.
On request, customized supports can be made for particular configurations.
The system, in addition to supporting the models to be tested, is able to set the pitch and yaw angle through to the remotely controlled actuators and the position sensors.
LOW SPEED SECTION
| Pitch excursion from -15° to +30° |
| Yaw excursion ±30° |
