Abstract
In lucrare se prezinta cazul inlocuirii unui unui turbomotor de generatie veche cu un turbomotor mai nou pentru utilizare marina. Noutatea consta in solutia de adaptare mecanica datorita aspiratiei si evacuarii gazelor aflate in pozitii opuse fata de cele ale ale turbinei vechi. De asemenea, a fostrealizat și implementat un sistem de comanda si control complet adaptat cerintelor navale. Testele la care a fost supus noul motor, in regimuri apropiate de cele ale turbinei înlocuite, au arătat că înlocuirea cu noul motor a făcut ca propulsia navei sa devina mai eficienta.
The paper presents the case of replacing an out-of-date gas turbine with a newer turbine for marine use. The novelty consists in the solution found for the mechanical adaptation due to the reversed gas inlet and outlet ports of the engine, located in opposite positions to those of the old turbine. As well, a customized command and control system was designed and implemented, in full accordance with the requirements of the ship. The tests to which the new turbine was subjected, in regimes close to those of the old turbine operation, have shown that the replacement of the turbines made the propulsion of the ship more efficient.
