Effects of Roll on the Free-Flight Motion of Statically Stable Bodies

摘要

The effects of roll on the free-flight yawing motion of statically stable test models, having linear force and moment characteristics, are discussed in more detail than in previous publications. The correspondence between the damping, frequency, and amplitude of the nutational and precessional vectors which define the motion is listed. Limitations in the use of simplified data reduction procedures when the model motion is monitored in only one plane are pointed out, and cases of pseudo-nonlinear characteristics being exhibited by the orthogonal components of the yawing motion of a rolling motion are demonstrated.
