What three parts make up the rotor of a helicopter?

system,and tail rotor system. The rotor system is the rotating part of a helicopter which generates lift. The rotor consists of a mast, hub, and rotor blades. The mast is a hollow cylindrical metal shaft which extends upwards from and is driven and sometimes supported by the transmission.

What is the rotor on a helicopter called?

A helicopter main rotor or rotor system is the combination of several rotary wings (rotor blades) and a control system that generates the aerodynamic lift force that supports the weight of the helicopter, and the thrust that counteracts aerodynamic drag in forward flight.

What is the structure of a helicopter?

Ordinarily, helicopters have between two and seven main rotor blades. These rotors are usually made of a composite structure. The large rotating mass of the main rotor blades of a helicopter produce torque. This torque increases with engine power and tries to spin the fuselage in the opposite direction.

What weapons are on an Apache helicopter?

The Apache can be equipped with air-to-air missiles (Stinger, AIM-9 Sidewinder, Mistral and Sidearm) and the advanced precision kill weapon system (APKWS), formerly known as Hydra, family of guided and unguided 70mm rockets.

What are the rotor configurations?

The most common configuration is the combination of one main rotor and one tail rotor. The tail rotor compensates for the torque that is produced by the main rotor. The tail rotor also controls the helicopter along the vertical axis during hover flight. The arrangement of two rotors side by side was never very popular.

How are helicopter rotor blades made?

Composite Blades Today helicopter blades are made out of composite materials, including titanium, aluminum, stainless steel, carbon fiber, and fiberglass that cover a foam or Nomex core. This is down to the composite blades being designed in a way that uses crisscrossed layers of fabric to resist cracking.

What do the Taliban call the Apache?

Major Huw Williams, second in command of 3rd Battalion, The Parachute Regiment, stated that: “We’re really impressed [with the Apache]. It’s a very effective beast.” It has been noted that Taliban forces refer to the aircraft as the “Mosquito”.

How do Apache helicopters work?

How Apache Helicopters Work. As the main rotor spins, it exerts a rotation force on the entire helicopter. The rear rotor blades work against this force — they push the tail boom in the opposite direction. By changing the pitch of the rear blades, the pilot can rotate the helicopter in either direction or keep it from turning at all.

How do the blades on an AH-64A Apache work?

The rotor assembly on an AH-64A Apache. As the main rotor spins, it exerts a rotation force on the entire helicopter. The rear rotor blades work against this force — they push the tail boom in the opposite direction. By changing the pitch of the rear blades, the pilot can rotate the helicopter in either direction or keep it from turning at all.

How do helicopter tail rotors work?

The rear rotor blades work against this force — they push the tail boom in the opposite direction. By changing the pitch of the rear blades, the pilot can rotate the helicopter in either direction or keep it from turning at all. An Apache has double tail rotors, each with two blades.

Why is titanium used in aircraft like the Apache helicopter?

The titanium is strong enough to withstand brushes with trees and other minor obstacles, which is helpful in “nap-of-the-earth” flying (zipping along just above the contours of the ground). Apaches need to fly this way to sneak up on targets and to avoid attack.
