The results of the test programme performed on the sailing yacht 1:3 scale model C.2421, of the America's Cup Class (ACC) are presented. The tests were performed to determine the TH17A sailing yacht hydrodynamic characteristics in calm water towing conditions. The model belongs to the latest generation of hulls designed for the America's Cup 2003 PRADA Challenge, in order to choose the best hull to race. The experimental technique used is the so called partially restrained model. The model is free to heave and pitch, but restrained in the other motions. The Appended Heeled and Yawed Tests consist of the so called "stripping tests" that study the influence of the single components of the full appendages configuration. A reduced matrix of Unappended Tests was performed too.
Sono presentati i risultati del programma di prove eseguiti sul modello in scala 1:3 di barca a vela C.2421 (TH17A) di Classe Coppa America, al fine di determinarne le caratteristiche idrodinamiche al rimorchio in acqua calma. Il modello appartiene all'ultima generazione di scafi disegnati per la sfida di PRADA alla Coppa America 2003, al fine di scegliere il miglior scafo da far gareggiare. La tecnica sperimentale utilizzata è quella del modello parzialmente vincolato. Il modello è libero nel moto di sussulto e beccheggio e vincolato in tutti gli altri moti. Le prove in assetto sbandato con angolo di deriva sono state eseguite su varie combinazioni del set standard di appendici, ottenute togliendo alternativamente una delle appendici. È stata anche eseguita in formato ridotto la prova sulla carena nuda.

Abstract
The results of the test programme performed on the sailing yacht 1:3 scale model C.2421, of the America's Cup Class (ACC) are presented. The tests were performed to determine the TH17A sailing yacht hydrodynamic characteristics in calm water towing conditions. The model belongs to the latest generation of hulls designed for the America's Cup 2003 PRADA Challenge, in order to choose the best hull to race. The experimental technique used is the so called partially restrained model. The model is free to heave and pitch, but restrained in the other motions. The Appended Heeled and Yawed Tests consist of the so called "stripping tests" that study the influence of the single components of the full appendages configuration. A reduced matrix of Unappended Tests was performed too.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
