Blower Cooling of Finned Cylinders
This 1937 NASA technical report, published by the National Advisory Committee for Aeronautics, studies how blower air cooling performs on finned engine cylinders and is written for aircraft engine engineers. Its three pictures are plain technical charts: two plot heat transfer coefficient U in B.t.u. per square foot per degree per hour against horsepower per inch of cylinder length, with labelled curves for cylinders of different fin spacing, and one plots a logarithmic relation with a slope line through marked data points. A designer could borrow their clean grid-and-curve layout, tick-mark labelling and muted cream paper for infographic treatments of data.
