Overview. 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.

Are helicopter blades dangerous?
Rotating helicopter blades are especially dangerous to people out- side the aircraft when the helicopter is being powered down and the centrip- etal force on the main-rotor blades is reduced, allowing them to droop closer to the ground.
What is the stick in a helicopter called?
The cyclic pitch control, a stick-type control found to the pilot’s right, controls the direction of flight by tipping the plane of rotation in the desired direction.
What is a Jesus nut on a helicopter?
Jesus nut is a slang term for the main rotor retaining nut or mast nut, which holds the main rotor to the mast of some helicopters. … More generally, Jesus nut (or Jesus pin) has been used to refer to any component that is a single point of failure which results in catastrophic consequences.
What is inside a helicopter?
Typically, a composite component consists of many layers of fiber-impregnated resins, bonded to form a smooth panel. Tubular and sheet metal substructures are usually made of aluminum, though stainless steel or titanium are sometimes used in areas subject to higher stress or heat.
Why is it called a helicopter?
The English word helicopter is adapted from the French word hélicoptère, coined by Gustave Ponton d’Amécourt in 1861, which originates from the Greek helix (ἕλιξ) “helix, spiral, whirl, convolution” and pteron (πτερόν) “wing”.

Commercial plane travel is extremely safe, despite recent catastrophes like the Boeing 737 Max crashes; in many years the fatal accident rate in the U.S. is zero. Helicopters are more dangerous, according to data from the federal government, with a fatal accident rate of 0.72 per 100,000 flight hours in 2018.
Can a helicopter cut your head off?

How do helicopters go forward?
Only the main rotor is used to move the helicopter up and down, and to make the helicopter tilt forward, backward, left, or right. … By tilting a blade to increase the blade’s angle of attack, the pilot can increase the force of lift that is pushing up on that blade.
Why is helicopter pilot on right side?
Most helicopters these days have a collective for each seat, located on the left, so the pilot wants to use the hand in the middle of the cockpit to work the radios and things. Hence, they sit on the right side, which places the collective hand in the middle of the cockpit.
How are helicopter blades attached?
In a fully articulated rotor system, each rotor blade is attached to the rotor hub through a series of hinges that let the blade move independently of the others. … The vertical hinge, called the lead-lag hinge or drag hinge, allows the blade to move back and forth.
