SYSTEM FOR DETERMINATION OF PARAMETERS OF TRIM OF DAMAGED SUBMERSIBLE VEHICLE IN SURFACE POSITION UNDER SWELL CONDITIONS Russian patent published in 1998 - IPC

FIELD: shipbuilding; determination of parameters of static trim conditions. SUBSTANCE: system includes dynamic and static clinometers, trim gauge and draft gauge, computer, annunciator, control unit and self-contained power supply source; each dynamic and static clinometer and trim gauge are provided with angle sensor which is located near vehicle CG. Static draft gauge is made in form of electronic transducer and straight metering tube which is provided with water column length sensor whose output is connected with input of electronic transducer. Dynamic draft gauge has its own electronic transducer and two pressure differential sensors located below minimum draft; their axis coincides with axis of metering tube. Each pressure differential sensor is brought in communication with outboard space at one inlet by means of pipe and with atmosphere at other inlet through air intake by means of another pipe line. Outputs of pressure differential sensors are connected with inputs of electronic transducer of dynamic draft gauge. Outputs of dynamic and static clinometers, trim and draft gauge are connected with inputs of computer through control unit. EFFECT: enhanced accuracy of determination of static trim of damaged vehicle in surface position under real conditions. 4 cl, 1 dwg
