In August 2019, the 0.6m×0.6m continuous transonic wind tunnel, FL-61 wind tunnel, was newly equipped with one 1.2m(width)×0.6m(height) test section for icing research and testing.

The flow field of this new test section was well calibrated and is in accordance with the SAE ARP 5905. With this new test section, icing test was performed for one domestic customer in September, 2019.

The performance specifications of the FL-61 wind tunnel relevant with icing test are as follows:

Liquid water content (LWC)0.2 to 3g/m³;

Drop size and median volume diameter (MVD)15to 50μmmax to 100μm;

Cloud uniformity, LWC:±20 percent;

Test section temperature: -40℃ to 5℃, Temperature rate:1℃/min;

-30℃ to 5℃, accuracy: ±0.5℃;

-40℃ to -30℃, accuracy: ±2℃

Pressure Altitude: max to7000m, accuracy: ±50m;

Control rate: 150 to 200m/min;

Spray operation time: Spray at least continuously 60min;

Bleed Hot Air Supply system: Temperature: max to 400℃, accuracy:±5℃;

Mass flow:0.01 to 0.1kg/s, accuracy: 2g/s;

Pressure: max to 0.4MPa, accuracy: 005Mpa;

Sustainable gas supply.
