摘要
滑行艇采用两个泵作为动力的水下喷水系统,分别置于船体的尾部两侧,对不同工作状态下的喷水推进艇的喷水泵和倒航斗受力和力矩进行了分析,并根据船舶MMG运动方程建立了双泵喷水推进艇的操纵性模型,对喷水推进艇的在不同的运行状态下进行了仿真。仿真结果表明,双泵推进操纵装置既可以作为控制面来控制喷水艇的航向,又可通过倒航斗使喷水艇正航和倒航,并能使它原地旋转和横移,喷水推进装置具有优良的操纵性能。
Planning craft adopts two pumps as underwater power to push the system, which is placed in the stern of the ship body both sides respectively. The thrust and torque of the pump and the split duct deflector were analyzed under different working conditions, and on the basis of MMG, the mathematical model of waterjet maneuver motion of twin waterjet-propulsion units was built and the performance was simulated. The result show that the steering device can be applied as a controller aboard to maneuver ship, to propel the ship both in ahead and astern conditions, and to put the ship turn in its position and move transversely, and this propulsion device has excellent maneuvering performance.
