Definitions

  • the invention relates to a jet drive for water and aircraft and circulation pumps, in which the fluid flowing into a jet pipe is accelerated against the intended direction of propulsion by a rotor designed as a screw, in which the outer edge of the screw is firmly connected to the inner jacket of the jet pipe. so that screw and jet pipe rotate together, in which the jet pipe is driven on its outer jacket, in which the jet pipe is mounted in a cladding tube or cladding tube housing and the like.
  • Such a jet drive is known from DE utility model 1 997 210.
  • a propulsion element arranged in the interior of the rotor designed as a jet pipe consists of a one-piece full screw which takes up its clear interior. This protrudes on both ends of the jet pipe and protrudes in the direction of advance into a fixed inlet connection and on the other side also into a fixed outlet connection provided with blades in the opposite direction.
  • the jet pipe is driven via a gear rim arranged in the middle.
  • a propeller is also known, the wing of which is penetrated or interrupted by a wing-like nozzle ring, in the latter case the inner wing parts should have a different pitch.
  • the wing-like design of the nozzle ring is intended to ensure that a strongly converging water flow to the propeller generates a negative pressure on its inner surface and an excess pressure on the outer surface in the sense of an additional thrust.
  • the nozzle In both types of execution, the nozzle must of course have the length of the projection of the wing width, as intended.
  • DE OS 33 43 605 already discloses a jet pipe with respect to one embodiment of the invention, which is designed to converge at the inlet and is narrowed to an annular space by a displacement body.
  • the object of the invention is therefore to avoid vortex losses and, if possible, to detect the entire inflowing amount of fluid in the sense of increasing the useful output, so that, as a rule, an empennage is also saved.
  • boat drives and a circulating pump can also be used on aircraft with a corresponding adjustment.
  • the subject of registration works as follows:
  • the fluid located in the jet pipe 11 is set in rotary motion by the edge worm 17 and strikes the fluid located in the free central passage with the still sucked-in fluid and also accelerates it in the direction of passage, as a result of which a strong driving force acting almost over the length of the jet pipe 11 by releasing part of the kinetic energy from the blades to the central flow.
  • the fluid on the front face is continuously drawn in without eddy formation.
  • the central flow compensates for the torque exerted on the overall arrangement, so that, in addition to the vortex-free inflow and avoidance of eddy formation at the exit, a propulsion force not previously achieved results.
  • An empennage at the output end of the jet pipe 11 is also generally saved in an advantageous manner.
  • jet pipes 11 of a jet drive 10 are each rotatably mounted in a cladding tube housing 12 on bearing rings 13.
  • the cladding tube housing 12 are formed in one piece with brackets 14.
  • the jet pipes 11 are driven by toothed belts 15, the teeth 15a of which mesh with a toothed ring 16 arranged on their outer jacket.
  • An edge worm 17 serves as the propulsion element, which is attached with its outer edge to the inner jacket of the jet pipe 11 and only covers an outer field of the interior of the jet pipe according to the sectional view II-II in FIG. 1a. The same arrangement is shown in FIG. 2.
  • FIG. 3 shows a drive pinion 19 of a motor indicated by its drive shaft 20 for the drive of the jet pipe 11 already described; 4, the pinion 19 meshes directly with the ring gear 16 of the jet pipe 11.
  • the jet pipe 11 is designed as a rotor of an electric motor and carries an armature winding 21 which is supplied with current via a collector 22. A magnetic winding 23 is indicated on the outside.
  • FIG. 6 shows a pressure medium drive with a feed line 24 and a return line 25 and the turbine 26.
  • the last two types of drive discussed are shown in greater detail in FIGS. 7 and 8 and, in particular, show the cladding tube housing 12 more clearly.
  • the magnetic winding 23 is accommodated in the recessed chamber 12a in the cladding tube housing 12; in such a chamber according to FIG. 8, the pressure medium acts on blades 28 on the jet pipe 11 via nozzles 27 that direct it.
  • FIG. 9 illustrates the arrangement of a jet engine 10 according to the invention in a boat 1.
  • an outlet pipe 29 protruding aft at the rear 1 b is held on a stand 2 arranged on the floor by means of a bracket 3 a surrounding the same.
  • Another tube 30 is held at the other end of the stand 2 with its end in a bracket 3b and connected to a water inlet opening 1c in the bilge 1a.
  • the drive shaft 20 of a motor 31 is mounted, the drive pinion 19 of which engages on the ring gear 16 of the jet pipe 11. It is obvious that instead of the drive pinion 19 a larger drive spur gear is used and around it e.g. can drive several jet pipes 11 in a pitch circle. This is indicated schematically in FIGS. 10 and 11 by toothed belts 15.
  • the drive shaft 20 of a boat 1 is inserted into a housing 10a which surrounds the jet engine 10 with the jet pipe 11 and gearbox.
  • FIG. 13 shows an outboard motor 34 which represents a motor 31 and the above-described jet engine 10 as a unit and which can be detached from the stern 1b of the boat 1 with a flange connection 34a.
  • the outboard motor 34 can also be designed to be pivotable about a rudder shaft.
  • the jet pipe 11 is constructed in principle as in Figure 7, with the difference that here Cladding tube housing 12 is designed as a fitting with flange connections 35 and thus serves as a circulation pump in a liquid circuit, for example in a hot water line. It is obvious that both the lubrication and the cooling are not as prophematic as in conventional circulation pumps and that a quiet and therefore less noisy run is ensured, as a result of which the jet drive according to the invention is particularly distinguished here.
