Aeronautical wind tunnel VRSF/VAF

Product overview
LTG SC03 Fahrtwind-Simulators provide homogeneous air distribution across a 1.7 m² discharge area, meeting CFR § 1066 requirements for SC03 tests up to 96 km/h (60 mph). Stationary and mobile configurations support various test-cell layouts and constraints, with versions capable of operation at ambient temperatures down to -40 °C. Optional attachment nozzles increase discharge velocity for WLTP applications up to approximately 135 km/h.

Features

• Homogeneous air distribution over a 1.7 m² discharge area (CFR § 1066 compliance for SC03 up to 96 km/h / 60 mph)
• Available in stationary and mobile configurations to fit different test-cell layouts
• Wide ambient operating ranges (down to -40 °C for selected types)
• Optional attachment nozzle to achieve higher discharge velocities for WLTP testing (up to ~135 km/h)
