The research work presented in this paper focuses on two topics. The first addresses a propeller optimization for a highly modular twin screw autonomous underwater vehicle, taking into account the propulsion efficiency and a low noise and vibration level. This includesthe avoidance of cavitation in submerged and specified surfaced conditions and furthermore allows for a silent class notation. The second topic is a new approach to model ship-propeller interaction during fast acceleration maneuvers of the vehicle. This approach is deemed necessary for ships and submarines with high torque electric propulsion that can rapidly increase the rotation rate. In order to meet the high requirements for the propeller with an acceptable effort, a self-developed propeller series is used and a baseline propeller is optimized further. The simulation method for the prognosis of acceleration and deceleration performance uses a new unsteady formulation of wake fraction and thrust deduction as a function of the hull advance ratio within an analytical method. Main benefits of this method are a more realistic propeller operation point at high acceleration rates at maneuver start resulting in improved cavitation prediction. Maneuver predictions with the new approach are compared to CFD-simulations focusing on the wake fraction and thrust deduction during acceleration and deceleration of the vehicle.
