There are three basic classifications:
semirigid, rigid, or fully articulated
. Some modern rotor systems, such as the bearingless rotor system, use an engineered combination of these types.
What are the 3 types of main rotor system?
Main rotor systems are classified according to how the main rotor blades are attached and move relative to the main rotor hub. There are three basic classifications:
semirigid, rigid, or fully articulated
. Some modern rotor systems, such as the bearingless rotor system, use an engineered combination of these types.
What are the three types of helicopters?
There are three basic types:
hingeless, fully articulated, and teetering
; although some modern rotor systems use a combination of these.
What are the four main controls of a helicopter?
They are the
collective pitch control, the cyclic pitch control, and the antitorque pedals or tail rotor control
. In addition to these major controls, the pilot must also use the throttle control, which is usually mounted directly to the collective pitch control in order to fly the helicopter.
What are the different 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 the top part of a helicopter called?
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.
What are the legs of a helicopter called?
Fuselage
— The main body of the helicopter is known as the fuselage.
Can a helicopter fly without a tail rotor?
One significant advancement in the last decade has been the no-tail rotor, or NOTAR, helicopter. … As you now know,
vertical-lift flight is impossible without a tail rotor
to counteract the torque produced by the main rotor.
What is a helicopter with two rotors called?
Tandem rotor (or dual rotor)
A tandem rotor helicopter
has two main rotor systems and no tail rotor. Usually the rear rotor is mounted at a higher position than the front rotor, and the two are designed to avoid the blades colliding, should they flex into the other rotor’s pathway.
What are the 3 types of helicopter tail rotor?
There are four main types of tail rotor or anti-torque systems on today’s helicopters. The most common is the
multi-bladed rotor
, the Fenestron from Airbus, the NOTAR from MD helicopters, then the helicopters with no tail rotor, like the chinook.

What are small helicopters called?
Ultralight helicopters
are classified as ultralight aircraft by the FAA and as Very Light Rotorcraft (VLR) by the EASA.
How do helicopters go forward?
The rotor blades are pitched lower in the front of the rotor assembly than behind it. This increases the angle of attack — and creates lift — at the back of the helicopter. The
unbalanced lift
causes the helicopter to tip forward and move in that direction.
How high can a helicopter fly?

What happens when a helicopter engine fails?
If the helicopter engine stops,
everything will go quiet in the cockpit, and the machine will yaw violently to one side
. When this happens, the pilot needs to instantly lower the collective, taking the pitch off the rotor blades, and initiating a descent.
