WebA simplified view of aviation theory - What is rotor blade lead lagging? The helicopter rotor is powered by the engine, through the transmission, to the rotating mast. The mast is a cylindrical metal shaft that extends upward from—and is driven by—the transmission. At the top of the mast is the attachment point (colloquially called a Jesus nut) for the rotor blades called the hub. The rotor blades are then attached to the hub, and the hub can have 10-2… WebMotor components are classified into five main portions (1) to (5) as Fig. 1.2 shows. Fig. 1.2 Motor components.
