The drag of three compliant coatings was measured in the DTNSRDC 36-inch water tunnel. Two coatings were of the 'Kramer' type, while the other one was a closed-cell neoprene foam. The drag of the 2.032-m (80-in.) long and 0.737-m (29-in.) wide compliant coatings was compared to the drag of a smooth, solid reference plate.

The skin-friction drag of compliant coatings was measured using an axi-symmetric test model in a water tunnel for flow speed up to 4.5 m/s at the Reynolds number of 2.3 million. There were measurable drag reductions for up to 3% from three out of five compliant coatings tested. Only one coating showed a small drag increase, and the other had no change in drag. For all the tests, the 95% confidence level in measured drag reduction was 1% for flow velocities between 2.5 and 4.5 m/s. The error analysis suggested that the uncertainty was progressively increased with a reduction in flow velocity.

The construction and testing of selected compliant coatings for drag reduction are described. Included are the scaling relations, description of test bodies, types of coatings and methods of construction, testing procedures, the phenomenon of static divergence, qualitative analysis, and conclusions.

Research on skin friction reduction by compliant coating conducted at the University of Oklahoma during the past eight years is reviewed. At the University of Oklahoma wind tunnel experiments showed that compliant coatings composed of a thin sheet of polyvinyl chloride covering either a thin layer of liquid or a thin layer of polyurethane foam reduced the turbulent skin friction drag by as much as 40% on flat plates. Hot wire anemometer measurements also indicated corresponding reductions in Reynolds stresses and turbulence intensities in the boundary layer. An NACA 0009 airfoil was found to have as much as 30% less drag when equipped with a 'polyvinyl chloride-polyurethane foam' compliant coating. (Author).
