Yes, it's the Ram Air Turbine, which provides emergency electrical and hydraulic power. Unless this aircraft suffered a real problem, the most likely explanation is that the crew were conducting an in-flight check of the system, as part of a regular maintenance check.

We did one recently and it worked fine but was very noisy!
