Abstract

 

Inclination test is one of the most critical test phases for submarines and vessels. Its purpose is to determine the transverse metacentric height that characterizes the stability of the ship, and to adjust its value to the design value by changing the center of gravity of the ship via application of solid ballast. The basis of the inclination test is to determine the increments in inclination angles. The accuracy of angles measurements directly affects the accuracy of transverse metacentric height determination and stability of the ship as a whole. The article presents the results of practical application of new patent-protected recording instrument. In addition, method to process submarine inclination angles during the acceptance trials has been given, using the instrument under review, namely, the EU-1 electronic angle-measuring instrument. The article also provides comparisons with nearest analogues.

 

Keywords: angle measuring instrument, inclination test, list, stability, electronic, optical, submarine, tests.
