“…Using wing-assisted system two conditions, wing thrust increase 250kN when the wind speed increases 6 m/s at 4000s; and wing thrust reduce 250kN when the wind speed reduce 6 m/s at 10000s. [9] In the first condition rotational speed of the marine diesel engine to maintain1.572r/s. In the second condition rotational speed of the marine diesel engine reduce 0.25r/s at 4000s and increases 0.32r/s at 10000s.…”

In order to research on the disturbance characteristics of marine diesel engine with wing-assisted system, mathematical models of ship, diesel engine, propeller and wing were established. Disturbance characteristics of marine diesel engine which using the wing-assisted system was simulated by matlab/simulink software. The output torque and speed curves of the marine diesel engine at different conditions were obtained, by inputting different wing thrust fluctuation signal. The results can provide some reference value to the wing-assisted technology in the application of ocean transport ships, and which has a certain dominating significance for dynamic coupling of diesel-wing ship.

“…Shukla and Ghosh [4] showed that a certain sail-assisted ship can save 8.3% of its total energy consumption. Ren [5] [6] found out that sail-assisted ship can save fuel consumption and reduce exhaust gas emission by different approaches. Meanwhile, wind power generated on ships has also been proved to play a very efficient role in energy conservation.…”

A comprehensive energy-saving sail (CES) has been proposed in order to promote energy saving and emission reduction from shipping. Wind energy is harvested for propulsion and electrical generator at the same time by a unique structure of CES. A CFD (Computational Fluid Dynamics) code is verified by a case of arc wind sail, and it is used to simulate the pressure and velocity around the CES. The results show that the outlet velocity of air tunnel V o and wind velocity V i serve as an equation V o ≈ 1.31V i , which means the CES can effectively improve the conversion efficiency. In addition, it is found that V o increases with the tunnel diameter to some extend over which it will keep almost constant.
