What is the main rotor of the helicopter?
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 are the main parts of a helicopter?
The major components of a helicopter are the airframe, fuselage, landing gear, powerplant, transmission, main rotor system, and tail rotor system.

What is induced flow?
Induced Flow is the airflow which is forced through a rotor disk perpendicular to the disc. It is caused by the defllection of air by the passage of a rotor blade.
What are the 3 major components of the main rotor system discuss each?
Main Rotor System 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 purpose of the main rotor?
1 Introduction. The main rotor is the principal source of vibrations in a helicopter and the reduction of this vibration is important to increase the life of the components of the airframe as well as the comfort of passengers and crew.
What do helicopters land on?
A helipad is a landing area or platform for helicopters and powered lift aircraft. While helicopters and powered lift aircraft are able to operate on a variety of relatively flat surfaces, a fabricated helipad provides a clearly marked hard surface away from obstacles where such aircraft can land safely.
What is the base of a helicopter called?
Fuselage. The fuselage holds the aircraft together and accomodate passengers and cargo, as appropriate.
Do helicopters have 2 engines?
As twin-engine helicopters have two engines, they inevitably burn much more fuel; Typically twin engine helicopters are flown by more experienced pilots – thus salaries tend to be greater than those of the single engine marketplace.
How does a helicopter fly?
Unlike airplanes, helicopters feature spinning wings called blades or rotors on top. As a helicopter’s blades spin, they create a force called lift that allows the helicopter to rise into the air. The rear rotor can face different directions, allowing the helicopter to move forward, backward, and sideways.
