Abstract:

Basic Finner models are tested in both horizontal and vertical wind tunnels in order to develop dynamic testing techniques and to perfect new methods of non-linear analysis. The simple free motions of pure pitching and pure rolling are first studied. Then, free angular motions of combined pitching, yawing, and rolling are investigated. While the linear analysis methods appear to yield good results, the new nonlinear analysis methods are found to be essential in providing an accurate representation of the various motions and in providing correct values for the various static and dynamic stability coefficients.
