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.

Dark Blade 3-Channel R/C Helicopter $29.99 The Ultimate Mini Copter... Created by ThinkGeek Here at ThinkGeek it seems like no matter how many little R/C helicopters we fly, we're always looking for a new high with the next greatest model. Which is why we decided to kick the vicious copter cycle and go ahead and create the perfect micro indoor helicopter. The Dark Blade 3-Channel R/C Helicopter is an original ThinkGeek creation combining a futuristic drop-ship style design with precise flying characteristics and an innovative rear propeller system. Plus it just happens to be the smallest 3-channel R/C copter we've ever seen. So go ahead, enjoy the fruits of our helicopter obsession... we don't mind. Precise Control The secret of the incredible stability of the Dark Blade 3-Channel R/C Helicopter comes down to the torque control afforded by the dual rotor design. A traditional helicopter with only one rotor generates massive torque when the top blade spins. Normally this would cause the copter to spin out of control, but the rotor on the tail is designed to offset this torque. Therefore piloting a traditional helicopter involves constantly adjusting the tail speed whenever you increase the speed of the top rotor... difficult and time consuming to learn. The Dark Blade 3-Channel R/C Helicopter has dual rotors on the top which spin in opposite directions. These opposite spinning blades cancel out uncontrolled torque making for incredibly stable flight. For forward and reverse motion the tail rotor then blows up or down, pitching the copter forward or backward and causing it to move in that direction. It's a great control system and a pleasure to fly. Innovative Forward Propulsion System If you look carefully at the Dark Blade, you'll see two small side propellers that would appear to push the copter forward. Actually these side propellers are purely cosmetic. All the forward action happens with the small rear propeller hidden beneath the tail. This propeller then spins to pitch the Dark Blade copter forward or backward. In most small 3-Channel R/C copters the rear propeller needs to be mounted at some distance from the top rotors to get enough leverage to pitch the copter, this forces the helicopter design to be longer. However, the tail above the rear rotor in the Dark Blade acts to magnify the thrust of the propeller and allows a more compact 3-channel design.

How to Replace Your Bladerunner Rotor Blades The rotor blades are held in place by a short rubber tube at the very top of the main Blade Runner drive shaft. Remove this rubber tube and the Blade Runner rotor blades will then slide off along with the two plastic spacers that keep the rotors separated When replacing the rotors first slide on the lower rotor the one with two notches in the bottom of the stem Slide on the two spacers Slide on the upper rotor. The upper rotor is keyed to the D-shaped top of the main drive shaft and needs to be aligned in order for it to slide into place. This should not require much force when the parts are properly aligned Lastly slide on the transparent capping tube Note Not compatible with Bladerunner Search and Rescue Firefly or Micro Mosquito RC Helicopters.
