Reduction of a Push Convoy Manoeuvring Space in Inland Navigation by Drift Angle Control Using the Bow Active Rudder

The inland vessels, barges and especially convoys are facing problems related to their manoeuvrability in restricted waters. The paper presents an auxiliary steering device significantly improving manoeuvrability and reducing the required manoeuvring space of a shallow draft inland vessels. The principle of operation of the proposed active bow rudder is based on Magnus effect - the Magnus force generated on the rotating cylinder (rotor). The presented research, based on physical model tests, confirmed the applicability of the proposed solution. The results indicate a significant improvement in the manoeuvrability of vessels and pushed convoys due to the reduction of manoeuvring space by drift angle control.
