SYSTEM FOR STABILIZATION OF LONGITUDINAL MOTION OF HYDROFOILS

摘要

FIELD: navigation. SUBSTANCE: invention is related to equipment controlling hydrofoils. Increased stability of longitudinal motion of hydrofoil in seaways under mode of platforming is achieved by improved precision and quality of process of stabilization of center of mass required level of which is provided on still water by trim angle sensor 5, by trim angular speed sensor 6, by sensor 13 of depth of submersion of bow hydrofoil, by sensors 7, 8 of vertical acceleration which signals are summed by amplifiers 1, 3 of channels of control over drives 2, 4 of bow and stern elevators correspondingly. For achievement of set task there is provided circuit measuring depth of submersion of bow hydrofoil relative to level of still water which does not really exists in sea disturbance and vertical speed of center of mass composed of sensor 9 of lin ear accelerations and device 16 measuring inertial level. In device 16 signal of vertical speed of center of mass is obtained by way of addition of signal of angular speed of trim in summing amplifier 11 multiplied by ordinate Xn of bow hydrofoil and integrated by isodromic integrator 10 of signal of sensor 9 of linear acceleration. Signal proportional to depth of submersion of bow hydrofoil relative to inertial level is produced by summation of signals of sensor 13 of depth and speed of submersion of bow hydrofoil which compensates for lag of legitimate signal across low-pass filter 15. High stability of longitudinal motion of hydrofoil in seaways under mode of platforming is achieved by input of signal of vertical speed of center of mass of ship and depth of submersion of bow hydrofoil relative to inertial level into stabilization system. EFFECT: increased stability of longitudinal motion of hydrofoil. 2 dwg
