Pictured is a model to study the ice collection on struts in jet engines during flight. Researchers inspect the ice after the model encounters a simulated icing cloud during testing. Super cooled water created from the icing cloud that flows though the wind tunnel. The super cooled water forms ice on contact with the test model. Researchers then inspect the ice formation before laser scanning of the ice formation for further research and analysis.
