Abstract:

Over 50 all-composite helicopter main blades have been designed to date. More than 15 of these have reached either limited or full production status. Eight others are approaching production. This paper reviews the different design concepts and analyses that have been applied to many of these blades. Various design and analytical solutions to the problems of root end and drag link attachments, spar and blade transition sections, and tip weight and tip cap attachments are described. Author
