  • SDVs Swimmer delivery vehicles
  • Wet-Type SDVs where the swimmers are surrounded by water at all times and are using individual breathing apparatus (e.g., U.S. Navy Mark 8), and 2. Dry SDVs, where the swimmers are surrounded by air, and need to swim out of the SDV via an egress-ingress process (i.e., U.S. Navy ASDS).

  • the SDV includes a hull 10 which includes upper and lower hull portions 12, 14 divided by a generally horizontal chine 16. Front and rear sections 20, 22 of the hull are at different elevations, i.e., they include respective horizontal top decks 24, 26 that are at different vertical levels.
  • the window 28 includes a pair of transparent window portions 28a, 28b which converge forwardly and upwardly on opposite sides of a longitudinal centerline L of the vehicle to form a wedge like forwardly projected backwardly inclined surfaces and intersect at an upwardly/rearwardly inclined edge 30.
  • the window could be provided with an electrically conductive coating or with an embedded codactive sustance, for absorbing or reflecting electro-magnetic radiation, as is known in military aircraft windows technology.
  • the top front 24 and rear 26 decks are generally flat and horizontal and provided with hatches 40, 42, 44 to permit ingress and egress of swimmers, operators operating weapon and/or delivering ordnance.
  • Extending rearwardly and downwardly inclined from the rear edge of the top rear deck 26 is an inclined surface 48 which terminates at a stern edge of the vehicle.

  • the rudder 52 enables the vehicle to be steered in a horizontal plane. Steering in a vertical plane can be achieved by conventional front and/or rear lifting surfaces 56, 58 that are hinged to provide proper vertical maneuvering capabilities. The lifting surfaces could also be made retractable into the vessel hull, if desired.
  • An alternative configuration of propulsion and maneuvering means could relay on vectoring the propulsion mean (i.e. Waterjet or Arneson drive).
  • the bow 60 of the hull is sharply pointed as can be seen in Fig. 2.
  • the bow is formed by surfaces 62, 64 which are inclined upwardly and forwardly on opposite sides of the centerline L and intersect at an upwardly/rearwardly inclined front edge 66.
  • the vehicle is powered by one or more internal combustion engines 68 disposed in an engine compartment 70 (see Fig. 5).

  • an electric motor (68a) driven by batteries which may be recharged by the engine when the vehicle is surfaced.
  • the vehicle can be selectively operated as a combustion powered surface vessel or as an electrically powered submerged vessel.
  • the hull 10 comprises a pressure hull structure 90, shown in dark lines in Fig. 5, and an outer skin 92 (see also Figs. 5A and 5B).
  • the outer skin includes a pair of flat walls 94, 96 disposed on opposite sides of the centerline L, and converging upwardly toward the top decks 24, 26 and toward the rear tail 48.
  • the outer skin also comprises flat walls 98, 100 disposed on opposite sides of the centerline L and converging downwardly toward the hull lower portion 14 from outer edges of the walls 94, 96. At their rear edges, the walls 98, 100 converge rearwardly toward the centerline to merge into the vehicle's stern.
  • the interior of the vehicle is composed of pressurized compartments and non-pressurized compartments, as will be explained.
  • the pressurized hull structure 90 includes an outer pressurized hull 110, and an inner pressurized hulls 114, where 114 disposed within the outer pressurized hull 110.
  • the outer pressurized hull 110 surrounds the engine compartment 70 and a multi-level workstation 120 for human operators, including an operator's tower 122.
  • the workstation 120 is kept dry and under approximately one atmospheric pressure at all times.
  • the outer pressurized hull 110 extends forwardly from the workstation 120, and contains one or two inner pressurized hulls 112, 114 which define a swimmer ingress-egress chamber 134 and a housing compartment 136, respectively.
  • Spaces 138 formed between the skin 94, 96, 98, 100 of the hull on the one hand, and the outer pressurized hull 110 (Fig. 5B) on the other hand, are not pressurized and serve as ballast compartments for containing ballast water.
  • the housing compartment 136 is able to house swimmers, weapons and/or equipment in a wet mode and/or a dry mode.
  • a space 140 formed between the outer pressurized hull 110 and the inner pressurized hull 114 constitutes a transfer compartment for controlling the state (dry or wet state) of the housing compartment 136. That is, the transfer compartment 140 is substantially filled with water when the housing compartment 136 is substantially dry, and the transfer compartment is substantially dry when the housing compartment is substantially flooded.
  • the term substantially is used here to suggest that some water (or some air) may still occupy the 140 and 136 spaces even though they are in a dry (or wet) condition, respectively.
  • the housing compartment 136 constitutes a wet/dry compartment which when dry can be pressurized at atmospheric pressure to house swimmers and/or equipment (see Fig. 6).
  • the housing compartment 136 may be flooded by water transferred from the transfer compartment 140. Once the housing compartment 136 is substantially flooded and reaches the ambient external water pressure, swimmers can leave or enter the housing compartment through the trunk 39 and the hatch 40.
  • the ingress/egress chamber 134 communicates with both the workstation 120 and the housing compartment 136 via respective hatches 150, 152 (and respective trunks) to enable personnel to leave or enter the vehicle through the upper hatch 42 when the vehicle is on the surface or only slightly semi-submerged. Also, swimmers may enter or leave the vehicle via the ingress/egress chamber 134 when the vehicle is submerged. That is, by pressurizing the air in the ingress/egress chamber 134 to equal the ambient external water pressure, swimmers may exit the ingress/egress chamber 134 through the bottom hatch 154.
  • the ingress/egress chamber 134 can also be flooded with water from the transfer chamber 140 (while transferring air to the chamber 140) to enable swimmers to enter or leave through the upper hatch 42, so in this case the ingress/egress chamber 134 becomes a wet/dry compartment in a similar manner described above for the housing compartment 136.
  • Fuel for the vehicle may be contained within flexible bladders 160 located in the ballast compartments 138. The bladders are surrounded by water, so as fuel is consumed and the bladders shrink, water can be added to the ballast compartments to enable space formerly occupied by fuel to become occupied by water. Thus, the trim and balance of the vehicle are maintained substantially intact while fuel is consumed.
  • Figure 8 depicts a condition when the vehicle is in a semi-submerged mode, i.e., the transport compartment contains enough water to cause the vehicle to partially submerge.
  • Fig. 9 depicts a condition when the vehicle is a surface craft, i.e., most of the water has been evacuated from the transfer compartment 140 and the ballast compartments 138.
  • the vehicle can be operated as a surface vessel, with the water level at Wl in Fig. 1.
  • the ballast and transfer compartments 138, 140 are flooded with water, the vehicle can be operated as a fully submerged vessel, with the water level at W2 in Fig. 1.
  • the vessel can be operated in partially submerged states, i.e., variable freeboard operation, with the water level at W3 or W4, for example, as shown in Fig. 1.
  • Swimmers can enter or leave the vehicle while in fully or partially submerged states by means of the wet/dry housing chamber 136, or the ingress/egress chamber 134, which can be converted between wet and dry operation without adversely affecting the trim or balance of the vehicle.
  • the consumption of fuel is compensated for by adding water around the flexible fuel bladder 160 to compensate for the loss of fuel volume, thereby maintaining trim and balance.
  • the vehicle may serve as a littoral fighting vehicle and conduct numerous types of missions in addition or as alternative to swimmer delivering, such as: carrying and operating surface-to-surface ordnance while operating as a surface craft, or as a reduced freeboard low signature craft, carrying and operating underwater ordnance, carrying and operating electro-optical targeting systems, carrying and operating underwater acoustic targeting systems, carrying and operating obstacle avoidance sonar (OAS), - carrying and operating Doppler Navigation Sonar (DNS), and carrying and operating Electro Optical periscope(s).
