  • Cuffed aircraft propeller
    Patent number: 4642028
    Abstract: A variable pitch propeller is provided with a blade cuff, with a radially inner portion of the cuff formed in closely surrounding relation to the cylindrical shank of the blade, and with a nose portion of the cuff extending radially outwardly and smoothly flaring to the full cordwise dimension of the cuff, through the conventional blade opening in a spinner. The arrangement eliminates regions for ice entrapment or build-up, and permits a heater boot to be applied to the leading edge down to or even into the blade opening.
