UNMANNED SUBMERSIBLE VEHICLE Russian patent published in 1998 - IPC

FIELD: inspection of underwater objects and local regions of bottom. SUBSTANCE: unmanned submersible vehicle includes four cruising propulsors mounted in channels located symmetrically relative to pressure hulls; one vertical propulsor mounted below center of mass in channel located in line of intersection of midstation plane and centerplane. Unit for securing the SPC cable is located in area of center of mass of unmanned submersible vehicle. Two log running propulsors are mounted in channels located symmetrically relative to midstation; they adjoin channel of vertical motion propulsor on opposite sides. These channels are located between two lower channels and midbodies of pressure hulls whose diameter is lesser than those of end sections of hulls. Non-pressure hull is lens-shaped in form. All propulsors are arranged in channels between cascades of blades which are mounted rotatably in guides only in channels of log running propulsors. End sections of pressure hull are provided with semispherical portlights with TV cameras mounted by means of universal joints. Swivel light sources are rigidly secured on the outside. EFFECT: enhanced reliability. 8 cl, 7 dwg
