项目摘要
This research project began six years ago. First of all, the robot which rowed the third scale model of "Ro"automatically, was produced in order to make clear the hydrodynamic characteristicsof rowing "Ro"and was completed for three years. The results of tank tests of rowing "Ro"by this robot proved that the "Ro"was an excellent propulsion device to achieve high efficiency.The multi vertical blades advancing in a row right to left on the front line and left to right on the back line with an appropriate attack angle were set up in a mechanism as a new propulsion device. This was named"The lateral motion blades type propulsor."The tank tests of this new propulsor were carried out in the Ship Model Basin of Yokohama National University. As the results, it was found that this propulsor could not attain excellent performances hydrodynamically because of great losses of the driving system and the turning system of blades.The improvement was tried in many times so as to overcome the great torque and shocking vibration which occured during turning of blades at the end of driving lines. However, even in the last year of this project, the successful results have never been obtained yet but the efficiency of this new propulsor has been up to twenty percent. The driving and turning mechanism of blades will be renewed in the near future.
这项研究项目始于六年前。首先,为了弄清“Ro”的水动力特性,研制了自动划动“Ro”第三比例尺模型的机器人,历时三年完成。该机器人划艇“Ro”的水槽试验结果证明,“Ro”是一种性能优良的高效率推进装置,其前线多个垂直叶片以适当的攻角从右向左推进,后线以从左向左的方向连续推进,是一种新型的推进装置。这种新型推进器的水槽试验是在横滨国立大学船模水池进行的。结果发现,该推进器由于驱动系统和叶片回转系统损失较大,水动力性能不佳,为克服传动线末端叶片回转时扭矩大、振动大等问题,多次进行改进。然而,即使在这个项目的最后一年,还没有取得成功的结果,但这种新的推进器的效率已经达到了20%。叶片的驱动和转动机构将在不久的将来更新。
