Résumé du livre
Specific free-to-trim tests were made on a 1/12-size model of a streamline fuselage modified by patterns of air jets or strips on the fuselage bottom. The effects of spacing of jets, length of jet rows, and direction of jets were determined for a simulated chine configuration. Tests were also made of a simulated multiple-step configuration. The effect of air flow on both the chine the step configurations was studied. In addition, the effect of substituting narrow breaker strips for the rows of jets in the chine configuration and in three multiple-step configurations was investigated.
