Experimental Investigation of Aircraft Propellers Exposed to Oblique Air Currents
This 1930 technical report from the NASA Technical Reports Server, an aeronautical research publication, presents experimental measurements of aircraft propeller thrust under oblique airflow, aimed at engineers and aerodynamicists. Its pictures are plain graph plots on squared grids, with labelled curves of thrust coefficients against angle and advance ratio, offering a designer little beyond the rhythm of rising and falling line charts and their ruled grid patterns.
