Analysis of Motion in Longitudinal Plane of Negative Buoyancy Vehicle
Abstract: This article described a novel type of autonomous underwater vehicle and modeled the dynamics. This kind of vehicle looked like an air-plane with large wings and worked under the condition of negative buoyancy. The motions of negative-buoyancy-vehicle (NBV) in the longitudinal plane were analyzed through linear system theory. This paper divided motion of NBV into a few modes in the longitudinal plane and provided a method of reduction of order to simplify the analysis, as well as gave the criterion of static stability under constant load in longitudinal plane. It had been found that the maneuverability and stability of NBV was related to many factors such as the velocity, lift-drag ratio, buoyancy and metacentric height. All of the conclusions could be applied on NBV design.
