Description

(54) УСТРОЙСТВО ДЛЯ ИСПЫТАНИЯ СУДОВОЙ ГРЕБНОЙ УСТАНОВКИ бопровод 10. соедин ющий камеры 7 с при емнум резериуаром II, выходит выше действующей ватерлинии. После притоплени  устройства, в него заводитс  кормова  оконечность судна 3, и судно раскрепл етс  с устройством тросами . При работе двигател  поток воды от гребного винта И по гидрокэналам 4 воЗ вращаетс  к винту 14. Дл  и.митации ходовых режимов и выбора скорости набегани  потока зоды на винт поток, воды в устройстве подтормаживаетс  поворотом заслонки 5 с помощью привода 6. При прохождении лопасти винта 14 у внутренней башни 3 воздушный пузырь в камерах 7 гасит силы сход щего t кра  лопасти гребного винта вихревого шнура, де 1ствующие на стенки башни. Воздушные полости через .резиновые перегородки воспринимаютс  колебани  потока от гребного винта и уменьшают их в 2- 4 раза, т. е. снижают напр жени , действующие на стенки камеры, а тем самым увеличивают надежность работы камеры и защищают ее от попадани  в резонанс.(54) DEVICE FOR TESTING A SHIP RING INSTALLATION b. 10. Connecting the chambers 7 with a receiver with a capacity of Resteriuar II, comes out above the current waterline. After the device is flushed, the stern end of the vessel 3 enters it, and the vessel is fixed to the device with cables. When the engine is running, the flow of water from the propeller And on the hydraulic channels 4 the WHO rotates to the screw 14. To imitate the driving modes and select the speed of the flow of the zods to the screw, the water in the device is slowed down by turning the valve 5 with the help of the actuator 6. 14 at the inner tower 3, the air bubble in the chambers 7 extinguishes the forces of the converging t edges of the propeller blade of the vortex cord acting on the walls of the tower. The air cavities through the rubber partitions perceive the flow oscillations from the propeller and reduce them by 2-4 times, i.e., reduce the stresses acting on the chamber walls, and thereby increase the reliability of the chamber and protect it from resonance.
