Hydrodynamic and aerodynamic tests of a family of models of seaplane floats with varying angles of dead rise
This is a 1939 NACA technical report, issued by the National Advisory Committee for Aeronautics, covering hydrodynamic and aerodynamic wind-tunnel and tank tests of seaplane float models with varying dead-rise angles, aimed at aircraft engineers. The first picture shows three float-hull models with differing bow shapes photographed on a plain background and one mounted in a wind tunnel. The second is a chart plotting lift, drag, and moment coefficients against speed coefficient, with curves for two spray strip conditions, offering a designer a clean line-graph reference.
