Could someone explain construction and working of helicopter blades.?

In the 1960’s, quite a while back I know, but I was working on helicopters. Just like to know the difference and some technology involved in the new blades. Some of the older one were made of wood, some aluminum honeycomb, and others were just aluminum skin, nothing inside for support.

Frank Piaseki used steel tubing, spruce wood, birch plywood and fabric to construct the rotor blades of his PV-2. Today, almost all military and civilian rotor blades are made from polymer composites. Blades are designed with specific geometry that adapts them to the varying conditions of flight. Cross-section shapes of most rotor blades are not the same throughout the span. Shapes are varied along the blade radius to take advantage of the particular airspeed range experienced at each point on the blade, and to help balance the load between the root and tip. The blade may be built with a twist, so an airfoil section near the root has a larger pitch angle than a section near the tip. Without polymer composites, the complex airfoils of today’s rotorcraft would likely not be possible.
