PURPOSE: An observation system for propeller cavitations of full-scale ship is provided to automatically operate even if a rotary shaft and a rotary are slightly slip. CONSTITUTION: An observation system for propeller cavitations of full-scale ship comprises a rotary encoder(100), an optical sensor(200), and a pulse control unit(300) and a stroboscope(400). A rotary(110) is mounted on the rotary encoder revolves in contact with the solid line propeller rotary shaft. The continuous pulse is occurred in the rotation of the said furnace Turley. The optical sensor generates a pulse on the tape attaching place by compartmentalizing the color of the tape(210) attached on the solid line propeller rotary shaft and color of the rotary shaft. |
