Abstract

L'invenzione riguarda un dispositivo per l'individuazione della formazione di ghiaccio sulle pale di un rotore di aeromobile. A questo scopo esso comprende un sensore di sforzo di trazione (10) ed un sensore di coppia (11) per misurare la forza assiale e la coppia esercitate sull'albero del rotore, mezzi (12) per calcolare il rapporto tra queste due grandezze, mezzi (12) per determinare, in funzione delle condizioni di volo, il valore nominale di questo rapporto in assenza di ghiaccio e, mezzi (12) per confrontare il rapporto calcolato con il rapporto nominale.(fig. 2)
