Towing-tank resistance and self-propulsion experiments are presented for the 1:12 scale model submarine C.2384. The tests were performed to compare the hydrodynamic characteristics in deeply submerged conditions between two propellers of new design, a six-blade propeller and a seven-blade one. The 6-component balance Remmers R-62 for submerged bodies was used in the experiments. Preliminary tests were performed for assessing the effects of the towing strut interference and of the stimulation on the hull, as well as unappended tests were added, just for determining the added resistance due to the appendages.
Sono presentati i risultati delle prove di rimorchio ed autopropulsione a quota profonda eseguite sul modello in scala 1:12 C.2384. Le prove hanno lo scopo di confrontare le prestazioni idrodinamiche tra due configurazioni di falsatorre. Per le prove è stata utilizzata la bilancia a 6 componenti Remmers R-62 per corpi immersi con modello vincolato. Secondo la metodologia in uso nell'Istituto le prove sono state precedute da test preliminari per la taratura del braccio di traino e lo studio della stimolazione, così come da una valutazione del peso idrodinamico delle appendici.

Abstract
Towing-tank resistance and self-propulsion experiments are presented for the 1:12 scale model submarine C.2384. The tests were performed to compare the hydrodynamic characteristics in deeply submerged conditions between two propellers of new design, a six-blade propeller and a seven-blade one. The 6-component balance Remmers R-62 for submerged bodies was used in the experiments. Preliminary tests were performed for assessing the effects of the towing strut interference and of the stimulation on the hull, as well as unappended tests were added, just for determining the added resistance due to the appendages.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
