These are also known as propellers. The blades are streamlined to form an airfoil, which allows them move efficiently in the air. It’s designed like the feathers of birds.
There are additional components. The tail rotor is smaller version of the top rotor blades that assists the helicopter in maneuvering the air. The Main Rotor Assembly provides power for the blades. Stabilizer is situated at the side of the helicopter. It assists in keeping the helicopter at a level, and avoid dipping either one side or the other. Under the stabilizer is the Tail Boom, which provides an engine for the stabilizer. The Engine and Transmission are the heart of the helicopter. This engine provides power for the entire machine. The Wheels are found under the tail boom as well as the cockpit, and they help the helicopter get around on the ground. Some helicopters are equipped with skids instead of wheels. The passenger doors are at the rear of the helicopter, behind the cockpit. You will also find the seats for passengers behind the cockpit. A few helicopters do not come with these seats. tsowdzufl7.
