NUWC-Russia-UK Collaborative Research on Compliant Coatings

We report the results from a collaborative effort between NUWC, Russia and UK on the development of compliant coatings for undersea application of drag reduction and turbulence control. The coatings were manufactured in Novosibirsk in Russia. The coated cylindrical models were shipped to NUWC and to the University of Nottingham in the UK. Some reduction in drag and wall-pressure fluctuation spectra has been observed on a small cylinder model. Further confirmatory tests are recommended with a large diameter model.
