The Effects of Various Parameters on the Load at Which Spray Enters the Propellers of a Flying Boat

Abstract

The results of experiments made for investigating spray characteristics of flying-boat models are discussed. Minimum load at which spray strikes powered propellers was determined for range of speeds and trims. Pressure or velocity spray may limit gross load of flying boat, depending on configuration. Increasing power reduced load at which spray entered propellers. Increasing trim increased minimum load at which spray entered propellers, but corresponding load for velocity varied with trim. Normal lateral and longitudinal positions of propellers tended to be near position that gave the smallest value of minimum load at which spray struck propellers.
