ABSTRACT:
A method for making a helicopter rotor blade having a longitudinal axis and a monolithic spar comprising a longitudinally-extending counterweight, a root member attached to the counterweight, and a retention means retained by and projecting laterally from the root member. A plurality of longitudinally-extending fibers is assembled into a group and is wrapped around the retention member and brought back at least partially upon itself, and then the foregoing elements are bonded together to form a solid spar member. A longitudinally-extending spacer member and the spar member are placed between a top skin section and a bottom skin section, each of which skin sections extends laterally and has a leading edge and a trailing edge. The leading edges abut each other and the trailing edges are bonded to each other. Preferably the trailing portion of this blade is hollow and unsupported internally.
