Definitions

  • the propeller 12 Due to the working mechanism of the propeller 12 and ship hull, the propeller 12 produces a lot of turbulence and energy dissipation while generating the propulsive force. If the rotationalal speed of the propeller 12 is increased, more turbulence and energy dissipation will result, thereby failing to enhance propulsion and speed of the marine vehicle 1.
  • the marine vehicle of the present invention comprises a hull, a propeller mounted to the hull and rotatable about a rotational axis, and a thrust boosting device mounted to the hull and disposed forwardly of the propeller with respect to a bow of the hull.
  • a reference line extends upwardly from and is perpendicular to the rotational axis of the propeller.
  • the thrust boosting device 2 is mounted to the hull 210 and is disposed forwardly of the propeller 201 with respect to the bow 205.
  • the thrust boosting device 2 includes a first fin member 21 disposed on the starboard side 202, a second fin member 22 disposed on the port side 203 and a third fin member 23 disposed on the port side 203.
  • Each of the first, second and third fin members (21, 22, 23) extends radially with respect to the rotational axis (L) of the propeller 201.
  • a distance (T) between the thrust boosting device 2 and the propeller 201 along the rotational axis (L) is 0.2 to 2 times a diameter (D) of the propeller 201.
  • the first fin member 21 forms a first angle ( ⁇ 1) in a clockwise direction with the reference line (S)
  • the second fin member 22 forms a second angle ( ⁇ 2) in the clockwise direction with the reference line (S)
  • the third fin member 23 forms a third angle ( ⁇ 3) in the clockwise direction with the reference line (S), all viewed from the stern 204.
  • the first angle ( ⁇ 1) ranges between 70° and 110°
  • the second angle ( ⁇ 2) ranges between 225° and 255°
  • the third angle ( ⁇ 3) ranges between 285° and 315°.
  • each of a distance (H1) between the first free end portion 212 of the first fin member 21 and the rotational axis (L) of the propeller 201, a distance (H2) between the second free endportion 222 of the second fin member 22 and the rotational axis (L) of the propeller 201, and a distance (H3) between the third free end portion 232 of the third fin member 23 and the rotational axis (L) of the propeller 201 is 1 to 1.2 times a radius (R) of the propeller 201.
  • the distance (T) between the thrust boosting device 2 and the propeller 201 along the rotational axis (L) is 0.2 times the diameter (D) of the propeller 201.
  • the first angle ( ⁇ 1) formed by the first fin member 21 in the clockwise direction with the reference line (S) is 90°
  • the second angle ( ⁇ 2) formed by the second fin member 22 in the clockwise direction with the reference line (S) is 230°
  • the third angle ( ⁇ 3) formed by the third fin member 23 in the clockwise direction with the reference line (S) is 300°.
  • the ship speed of the experimental group provided with the thrust boosting device 2 is higher than the ship speed of the control group without the thrust boosting device 2 when provided with the same horsepower.
  • the required horsepower of the experimental group provided with the thrust boosting device 2 is 5% lower than the required horsepower of the control group without the thrust boosting device 2 when moving at the same ship speed.
  • the propeller exciting force of the experimental group is lower than the propeller exciting force of the control group.
  • the second preferred embodiment of the thrust boosting device 2 of the present invention is similar to the first preferred embodiment.
  • the thrust boosting device 2 further includes a plurality of tip appendages 24 disposed respectively on the first free end portion 212 of the first fin member 21, the second free end portion 222 of the second fin member 22 and the third free end portion 232 of the third fin member 23.
  • the tip appendages 24 may alleviate tip vortex caused by the flow leaking from high pressure to low pressure near the free end portions 212, 222, 232 of the fin member 2.
  • the tip appendage 24 may have a shape of an elliptic streamline as shown in Figure 14 and Figure 15 , a plate as shown in Figure 16 and Figure 17 , or a curved plate as shown in Figure 18 and Figure 19 .
  • the present invention should not be limited to the second preferred embodiment.
  • the present invention utilizes the first fin member 21, the second fin member 22 and the third fin member 23 of the thrust boosting device 2 to change the upstream flow field of the propeller 201 before fluid flows past the propeller 201 so as to reduce the eddy kinetic energy.
  • This invention not only is low cost and low in complexity, but also is able to alleviate propeller exciting force and cavitation on the surface of the propeller 201, as well as to improve the propulsion efficiency and speed of the marine vehicle 200.
