Research on modeling technology for a high altitude airship

AbstractAccording of the force and motion characteristics of the high altitude airship, a six-degree-of-freedom nonlinear dynamic model is presented. On the basis of the model, the digital simulation is carried out. The motion parameters of the airship are analyzed on the little perturbation. Finally, the results show that the airship longitudinal and lateral motions are unstable and the coupling of the longitudinal and lateral motion is weak in several seconds
