Anotācija Abstract. The paper presents an original design of autonomous underwater vehicles where thrust force is created by the helicoidal shape of hull rather than screw propellers. The contrarotating bow and stern parts create propulsion force. The middle part of the vehicle, which is built from elastic material, contains a Cardan joint which controls bending drives (actuators). The controlled bending of the hull allows the maneuvering of the vehicle. A bending drive velocity control algorithm for the automatic control of the vehicle movement direction is proposed. The dynamics of AUV are simulated using multibody simulation software MSC Adams. For the simulation of water resistance forces and torques the surrogate polynomial metamodels are created on the basis of computer experiments with CFD software. The simulation results are compared with measurements of the AUV prototype, created at Institute of Mechanics of Riga Technical University. Experiments with the prototype showed good agreement with simulation results and confirmed the effectiveness and the future potential of the proposed principle.
