Abstract

See full text

A mechanical system for an aerospace application includes a drive input connected to a first axial end of a first diaphragm member, and a drive output connected to a second axial end of a second diaphragm member. The drive output is an aerospace component. The first and second diaphragm members are formed with two axial ends and at least one undulation extending radially of the axial ends. The at least one undulation is intermediate the ends. A tubular portion connects the first and second diaphragm members. The first and second diaphragm members and the tubular member are formed of fiber reinforced polymer matrix composites. The first and second diaphragm members are connected to axial ends of the tubular member by welding of the axial ends of the tubular portion to one of the inner ends of each of said first and second diaphragm members. The aerospace component is a propeller.
