Effect of afterbody length and keel angle on minimum depth of step for landing stability and on take-off stability of a flying boat /

Tests were made to investigate the effects of depth of step, angle of afterbody keel, and length of afterbody on the take-off and landing stability of a model of a flying boat. The results show that the minimum dept of step required to attain landing stability as a function of afterbody length and keel angle. An empirical formula is fitted to the results and it is shown that the formula agrees fairly well with the results from tests of other models.NACA TN No. 1571."September 1948."Includes bibliographical references.Tests were made to investigate the effects of depth of step, angle of afterbody keel, and length of afterbody on the take-off and landing stability of a model of a flying boat.
