Abstract
The usual natural gasoline of commerce is an extremely volatile product and quite unsuitable for direct use as a motor fuel in the conventional fuel systems of today. By careful fractionation, however, it has been found possible to produce “aviation natural gasoline,” a fuel that has made a splendid record commercially during the last three years. A considerable amount of research work has been done with regard to this product, and the author discusses it under the following heads: (1) Initial flight tests to determine specification bases for commercial purposes; (2) effects of changes in specifications for aviation natural gasoline; (3) survey of commercial aviation gasolines; (4) flight tests to determine actual temperature in airplane fuel systems; and (5) other investigations. An extensive table of test results of commercial aviation gasolines is included, as well as a bibliography of articles having a bearing on aviation natural gasoline.
