Static stability characteristics of a systematic series of stern control surfaces on a body of revolution

Experiments were conducted to determine the forces and moments due to angle of attack on a representative streamlined body of revolution alternately appended with members of a systematic series of stern control surfaces. The data from these experiments are presented in the report in the form of graphs and tabulations of the nondimensional force and moment coefficients and static stability derivatives. Based on these data empirical mathematical expressions have been developed to predict the contribution of sternplanes to the static stability derivative Zw: when the sternplanes are appended to a submarine whose basic hull is a streamlined body of revolution. A graph is presented for estimating the location of the center of pressure of the forces due to the presence of sternplanes.
