By usingthe known cross-section as well as the propeller shaft's material type the torque was determined. Knowing the shaft frequency, that is the radial velocity and the torque, it is possible to determine the effective power transmitted from the engine to the propeller. The equipment, i.e., the hardware and the software, was produced by HOTTINGER BALDWIN MESSTEHNIK (HBM),Darmstadt, from the Federal Republic of Germany. The experiment was carried out on a ship belonging to the Navy of Serbia and Montenegro under the conditions of a standard sailing regimeV tem prispevku je z uporabo merilnih lističev in osebnega računalnika, z nedotikalno metodo, opisan postopek merjenja elastične deformacije osi ladijskega vijaka. Na podlagi znanega prečnega prereza in vrste materiala osi ladijskega vijaka, je določen vrtilni moment. Z znano frekvenco osi, kotno hitrostjo in vrtilnim momentom je mogoee določiti delež koristne moči, ki se prenaša od motorja do ladijskega vijaka. Vsa uporabljena oprema pri preizkusih, tako strojna kakor programska oprema, je bila izdelana v podjetju "HOTTINGER BALDVIN MESSTEHNIK" (HBM), Darmstadt, Nemčija. Preizkus je potekal na ladji Mornarice Srbije in Črne Gore pri ustaljeni plovbiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
