Test results
The BorealisWind Ice Protection System (IPS) delivers highly effective results in preventing ice buildup on turbine blades. These test results illustrate the system’s ability to consistently meet or exceed temperature predictions under various environmental conditions.
Using targeted heating along the leading edge of the blade, the IPS ensures safe and reliable energy production, even in harsh climates. These infrared images and data comparisons highlight how the system performs under real-world conditions, validating its effectiveness in maintaining optimal blade temperatures.
Predicted vs. measured conditions and results
Example 1
This image shows a heated 50 meter long blade. The infrared photo was taken from the ground at an 80 meter tower. Heating is targeted to the leading edge of the blade, which you can see from the spot temperatures. The leading edge shows a temperature between 15.7°C and 21.2°C depending on the location. Due to the distance that the infrared photo was taken from, there may be +/-2°C of error.
The table shows the predicted temperatures and the measured temperatures. The ambient conditions were -2°C with wind speed around 2.2 m/s. The predicted blade surface temperature was between 14.5°C to 20.0°C.
Example 2
This image shows a heated 50-meter long blade. The infrared photo was taken from the ground at an 80-meter tower. The heating is targeted to the leading edge of the blade, which you can see from the spot temperatures. The leading edge shows a temperature between 8.3°C and 13.6°C depending on the location. Due to the distance that the infrared photo was taken from, there may be +/-2°C of error.
The table shows the predicted temperatures and the measured temperatures. The ambient conditions were -7°C with wind speed around 5.8 m/s. The predicted blade surface temperature was between 6.3°C to 12.9°C.
