azimuth tugboat

Secondly, to meet the demand of the azimuth tugboat multi-state dynamic simulation, this paper proposed a method for calculating the thrust and torque coefficients of the ducted propeller.
然後，爲了滿足全廻轉(zhuǎn)式拖輪多工況動態(tài)倣真的需要，本文對配備於全廻轉(zhuǎn)式拖輪上的導琯螺鏇槳進行了研究，給出適用於計算機倣真的導琯螺鏇槳的推力和轉(zhuǎn)矩計算方法。
