Definitions

  • Cataraman-type vehicle embodies (l) an airplane-type wing-like member connecting, and at right angles to, plural pontoons and (2) an inclined helicopter rotor forward of the wing-like member and adapted to blow an air stream under said connecting wing-like member.
  • the rotor shaft is mounted for inclination laterally as well as forward and backward.
  • the boat according to the invention consists of at least two (possibly three) pontoons and one or more wing like intermediate members located above the water surface and connecting the said pontoons.
  • the said wing like part of the boat which normally may contain compartments and load spaces shall have its foremost part so much of the stern as is the total width of the boat. This gives space for a helicopter rotor at the foremost part of the boat.
  • the invention is substantially characterized by the fact that an inclined helicopter rotor in the foremost part of the boat carries some half of the boat weight while it also provides the propulsion needed and gives to the wing-shaped part of the boat a high air velocity so that the lifting force of this part is great also at low cruising speeds.
  • the pontoons can be made of a shape similar to those ofa seaplane the step being, however, provided much farther forward. Between the said pontoons there are provided one or more wing-like members having the profile of an airplanewing which may contain compartments, motors or load spaces.
  • the gliding ratio of the bottom surfaces will be of secondary importance and therefore one is free, to a very great extent, to shape the said bottom surfaces in accordance with the demands of sea worthiness and stability in contradiction to the bottoms of a common plane-boat, in which everything must submit to the demand 'of a speed producing shape.
  • They also can have keels for preventing the passing out sideways of the air blown in under the wing like parts. These keels may, if so desired, serve as sledges if the boat is to be used on ice.
  • Backward motion can be obtained by tilting its rotational surface backwards.
  • the boat can brake very simply by shutting the. throttle. This will give to the rotor a downwards directed force which will give a braking force. It will also produce a greater pressure of the pontoons to the water and this will give a high resistance. So the boat is easily brought to stop.
  • FIG. 1 shows a side view of the boat and FIG. 2 is a top plan view of the boat.
  • the airplane wing-like member, 1, is part of the boat.
  • 2 is pontoon and, 3 the central steering house for the pilot.
  • This steering house has a fixing point for the rotor shaft 6, which fixing point can allow the rotor shaft and the rotor 5 to be inclined in any direction.
  • the motor 4 is situated in the foremost part of the steering house.
  • the tilting of the rotor can be performed for instance by any hydraulic equipment, which is not shown.
  • Under the pontoons we can see the keel 7 which prevents the air from flowing out sideways under the pontoons.
  • At the rear end of the boat there are fins 8 to give aerodynamical steering stability.
  • a boat to move on a surface of a body of water comprismg:
  • an intermediate connecting wing member having the profile of an airplane wing, extending across and rigidly fixed on the pontoons at a level definitely above the-normal waterline; v I y 3;
  • a helicopter-type rotor mounted in the foremost part of the boat and having a more lifiing than driving position and so disposed as, when in operation, to blow an air stream under said connecting wing member thereby inducing a lifting force to the wing member so that only a small percentage of the boat's weight is supported on the water surface;
  • said rotor having means for tilting the rotor to desired positions, more lifting than driving, for driving the boat forwards and backwards and for steering the same from side to side.
