The invention discloses a guide pipe with an adjustable attack angle. The guide pipe is characterized by comprising a shaft bracket, a shaft sheath is arranged on the shaft bracket, the shaft sheath is connected with guide pipe brackets, guide pipe sheet bodies are arranged at the other ends of the guide pipe brackets, the guide pipe sheet bodies are connected through elastic films, and a tail steel ring is arranged at the tail part of each guide pipe sheet body. The guide pipe is characterized in that the attack angle of the guide pipe is adjustable, so that the guide pipe can be always located at the optimal efficiency attack angle by adjusting the attack angle of the guide pipe for different working conditions of ship navigation, including different navigational speeds, different resistances and the like, and the overall propulsion efficiency and seaworthiness of a ship can be better improved.

    本发明公开了一种可调攻角的导管,其特征在于,包括轴支架,轴支架上设有轴包套,轴包套与导管支架连接,导管支架的另外一端设有导管片体,导管片体之间通过弹性膜连接,导管片体的尾部设有尾部钢圈。本发明的最大特征是导管的攻角可调,因此,对于船舶航行的不同工况,包括不同的航速、不同的阻力等,可通过调节导管的攻角,使导管总处于最优效率攻角,更有利于提升船舶的整体推进效率和适航性能。
