介绍了利用牵引风筝进行商船辅助风推进的性能研究。报告并没有侧重于这种系统的实际设计方面，因此没有得出实际可行性的结论，而是说明了假设该系统实际工作时在各种环境条件下所节省的燃料量。给出了风筝传递牵引力的估计值。根据表观风向和风速的不同，这种风筝作用力会造成船舶的漂移角度，从而产生额外的阻力。通过同时求解纵向和横向的力平衡和偏航平衡来考虑这一影响。最后，为了计算风筝辅助推进对船舶恒速油耗的影响，考虑了现有风筝推进系统在变工况下的性能。实例研究的结果表明，相对节油是风速和风向相对于风向的函数。
A performance study of auxiliary wind propulsion for commercial ships by means of a traction kite is presented. It is not focusing on practical design aspects of such a system and therefore not concluding on practical feasibility, rather it gives an indication of the amount of fuel saving in various environmental conditions assumed that the system is working practically. An estimate is presented of the delivered traction force of a kite. Depending on the apparent wind direction and wind speed, this kite force will cause a drift angle of the ship, resulting in additional resistance. This effect is taken into account by simultaneously solving the force balance in longitudinal and lateral direction and the yaw balance. Finally, in order to calculate the effect of auxiliary kite propulsion on the fuel consumption at constant ship speed, the performance in off-design conditions of the existing propulsion system is considered. Results of a case study are presented showing the relative fuel saving as a function of wind speed and wind direction relative to the sailing direction.
