How a helicopter hangs by its “elbows”

Straight up, straight down, forwards, backwards, or just hovering— the Piasecki “Work Horse” Helicopter’s peculiar flying maneuverability rests in its rotor assemblies. It is these flexible “elbows” that adjust the pitch of the ‘copter’s great blades. Each unit involves more than 625 separate parts. To machine and assemble them, Piasecki depends on Lycoming for precision production.
