Researchers test vehicle mobility and performance for Arctic environments
Orian Welling, a research mechanical engineer for the Engineer Research and Development Center’s Cold Region’s Research and Engineering Laboratory (CRREL), works inside CRREL’s winter mobility laboratory. The laboratory houses a Polaris MRZR heavily modified with numerous systems for detecting how the vehicle moves on terrain as it freezes to when it starts to thaw and anything in between. The winter mobility laboratory does a lot of research in Arctic regions, and all of their research is aimed at increasing Arctic or winter performance in Arctic environments.
