Definitions

  • This invention relates to the shipbuilding field and, in particular to the construction of hydroplane or planing craft provided with extendable interceptors.
  • hydroplanes or planing crafts that are known to have a hull with a deadrise bottom and controllable aft and forward interceptors (spoilers) mounted in recesses arranged in the bottom.
  • the high speed craft described in patent RU 2096240 of 1997 has a hull with a deadrise bottom provided with a forward and aft transverse planing steps and extendable interceptors that are mounted behind these steps and divided symmetrically into portside and starboard-side sections.
  • An automatic interceptor control system permits the interceptors to be used as pitch and roll control elements.
  • these hydroplanes use a propeller as a propulsive device, which is connected to the main engine located in the central or aft section of the hull by means of shaftlines supported by shaft brackets (Inventor's Certificate SU 1025574).
  • the present invention permits to combine the advantages of interceptors with those of waterjets on hydroplane, the resultant effect of using each of these components being supplemented by an additional effect obtainable at a certain arrangement of interceptors relative to the water-jet intake openings in the hydroplane's bottom.
  • a hydroplane has a hull with a deadrise bottom and aft extendable interceptors and is provided with one or more water-jets at the aft part of the hydroplane, the water intake openings of water-jets being arranged in the hull's bottom forward of the interceptors.
  • a hydroplane may also be provided with bow (forward) interceptors.
  • the bottom may have an aft and a forward transverse planing steps with interceptors, in this particular case, mounted behind the steps.
  • the deadrise angle of the bottom may vary along the hydroplane's length, the optimum angle range being 6° to 12° at the forward step and 0° to 6° at the aft step.
  • the hydroplane illustrated in Figure 1 has a hull 1 with a deadrise bottom 2 and aft interceptors 3 and 4 (for portside and starboard-side respectively) that are capable of moving out of a slot in the bottom (not shown) or from behind the aft transverse planing step 5.
  • the hydroplane is provided with one (or more) water-jet 6 mounted at the aft end of the hydroplane, the intake opening 7 of the water-jet 6 being arranged in the bottom 2 of the hull 1 forward of the interceptors 3 and 4 as shown in Figure 2.
  • the hydroplane may also be fitted with forward interceptors 8 and 9 that are located behind the forward transverse step 10, port and starboard.
  • the forward, or bow step 10 is arranged on the hull's bottom forward of its center of gravity 11. If necessary, the interceptors 8 and 9 can be divided into sections (not shown in the drawings) that are then controlled individually to compensate for pitch and roll motions in a seaway.
  • the aft interceptors 3 and 4 and the forward interceptors 8 and 9 if fitted are constructed with a sharp outer edge, which secures a continuous flow separation at the edge.
  • the deadrise angle of the bottom varies along the hydroplane's length from 6° to 12° at the forward step 8 to 0° to 6° at the aft step 4.
  • Optimum deadrise angles for each planing step of a specific hydroplane are determined from model tank tests. The increase of deadrise angles over the above-stated maximum values will result in a lower drag-lift ratio for the hydroplane while their decrease beyond the above-stated ranges will somewhat improve it but will also cause problems for stable planing and increase vertical accelerations experienced during the ride in a seaway.
  • the bottom surface of the hydroplane forward of each planing step has symmetrical flat areas that coincide with the areas of the bottom surface wetted during the planing mode of operation, as determined from the model tests.
  • the flat areas 12 forward of the forward planing step are of triangular or trapezoidal shape.
  • the flat areas 13 forward of the aft planing step may also have a trapezoidal shape but more often their outline is of more complicated form.
  • the travels of the forward and aft interceptors or their sections are determined depending of the speed of the hydroplane.
  • the optimum relationship is determined from the model tests with subsequent refining based on the results of full-scale trials.
  • Travel of the individual interceptors or their sections is controlled by an automatic control system that provides for an increased motion stability and better maneuverability of the hydroplane in the calm sea conditions and for roll and pitch motions damping and reduction of vertical accelerations when riding in a seaway.
  • the interceptors are retracted to a position within the planing steps (or into the bottom slots) to protect them from damage.
