Patent GB-820431-A (GB)
Title: Apparatus for the stabilization of ships
IPC: G05D1/08
Filed: 1957-08-01
Abstract: 820,431. Automatic ship stabilizing systems. SPERRY RAND CORPORATION. Aug. 1, 1957 [Sept. 17, 1956], No. 24443/57. Class 38 (4). In a ship roll stabilizing system the angle of attack of a stabilizing fin is automatically controlled in dependence on signals from an instrument responsive to rolling motion of the ship and signals dependent on the angle in a vertical plane which the local water flow stream lines at the fin make relative to the ship. In Fig. 2, roll of a ship is detected by an athwartship linear accelerometer 10, A.C. signals from which are applied, together with stabilizing signals from a rate-of-roll gyro 13 and roll accelerometer 15, to control a follow-up motor 18 producing an A.C. error signal by adjusting a signal generator 24. This error signal is applied through a diode limiter circuit 26 an amplifier 27 to control motor 33 which reduces the error and thereby stabilizes the ship by controlling a stabilizing fin 32 through an hydraulic system including a variable delivery pump 30 and an hydraulic ram 31. Positional and rate follow-up signals for motor 33 are respectively derived from an inductive device 35 and a generator 34. Follow-up signals are also applied to amplifier 27 from an E-type pick-off 42 detecting strain and hence actual lift of fin 32. Fin 32 is of the type having a flap which moves relative to the fin in the same sense as the fin moves relative to the ship. A signal representative of the fin lift which would obtain without vertical movement of the ship relative to the water is computed by an inductive device 47 to which is applied a voltage dependent on the square of ship speed and which is adjusted in accordance with displacement of ram 31. The voltage dependent on the square of ship speed is derived from a potentiometer 51 adjusted through a squaring cam 53 by a knob 54 which is set according to the ship speed. The difference between the signals from pick-off 42 and inductive device 47, which represent the effect of vertical movement of the ship relative to the water are applied through an amplifier 44 to diode limiter circuit 26 so that fin movement is limited to a different extent in each sense to allow for the different effective angles of attack due to vertical movement. Details of the diode limiter circuit, potentiometers in which are also adjusted by squaring cam 53, are described with respect to Fig. 3 (not shown). The extent of operation of motor 18 is limited by nut 20<SP>1</SP> operating in conjunction with a slipping clutch 19. Motor 18 influences a second similar system 91 adjusting a stabilizing fin 90 in the opposite sense on the other side of the ship. Sensitivity of control is adjustable to suit weather conditions by a knob 9 setting potentiometers associated with the outputs of detectors 10, 13 and 15.
