An investigation was made to determine the effects of vertical-tail size and length and of fuselage shape and length on the lateral static stability characteristics of a model with wing and vertical tails having the quarter-chord lines swept back 45 degrees.
An investigation was conducted to determine the effects of geometric dihedral on the low-speed static stability and yawing characteristics of an untapered 45 degrees sweptback-wing model of aspect ratio 2.61. The results of the tests indicated that an increase in positive dihedral resulted in an increase in the rolling moment due to sideslip and also caused the maximum value of rolling moment due to sideslip to ...
