Compression-ignition Engine Performance at Altitudes and at Various Air Pressures and Temperatures
This is a 1937 NACA Technical Note, issued by the National Advisory Committee for Aeronautics in the United States, reporting tests of a compression-ignition engine under reduced and varied air pressures and temperatures for aviation engineers. The three plates show a performance chart plotting pressures, temperatures and fuel quantities against inlet conditions, a sectioned combustion chamber with fuel-spray arrangement, and a photograph of the test engine and air-conditioning equipment. A designer might take from them the clean black-line technical drawing style, dense graph layouts and cutaway mechanical sections.
