Current methods of predicting lateral-directional dynamic stability using closed form small perturbation equations are often inaccurate. Flight test data usually shows Dutch-roll characteristics; in ...

Philadelphia, PA—One of the lesser known concerns about commercial aircraft is their stability on the ground during taxiing, takeoff, and landing. During these processes, planes must maintain ...

During ground take-off/landing maneouvres, aircraft landing gear can display unwanted oscillations, which are referred to as shimmy oscillations. Scientist are studying the dynamics of aircraft ...
