... of the gyroscope, and hence these gyroscopic moments directly exhibit on-axis responses. This new method yields a parametric framework for examining the previously unexplained cross-coupled responses of hingeless helicopters and demonstrates that, in addition to aerodynamics, intricate dynamic nonlinearities also...

...B. R. Nana Nbendjo A nonlinear model of inverted pendulum that exhibit unbounded single well φ 6 potential is described. The complete equation for one-dimensional wind-induced sway is derived. The harmonic balance method along with Melnikov theory are used to seek the effects of aerodynamic drag...

... of the follower force, the generalized function theory is used. Also, Peter’s finite-state unsteady aerodynamic model is considered. The governing equations are obtained using Hamilton’s principle. Furthermore, the Galerkin method is applied to convert the partial differential equations into a set of nonlinear...

... , m x , m y , m z are the aerodynamical force and moment coefficients, and A c and L c are a characteristic area and length, respectively. The resultant, squared wind velocity 33 v res 2 = v 0 2 + u 2 + 2 u v 0   sin   α w...

...James Rankin; Bernd Krauskopf; Mark Lowenberg; Etienne Coetzee The dynamics of passenger aircraft on the ground are influenced by the nonlinear characteristics of several components, including geometric nonlinearities, aerodynamics, and interactions at the tire-ground interface. We present a fully...

... launching of nanosatellites ( 1 – 10 + kg ) . Accurate engine, beam, and aerodynamics models are included to improve the predictive capability of the 7DOF code. The aerodynamic forces of lift, drag, and aerodynamic pitching moment were derived from FLUENT ® computational fluid dynamics predictions...
