Why is it necessary to have the tail rotor on the helicopter that spins perpendicular to the spin of the main rotor?
"For every action there is an opposite and equal reaction." For the helicopter to make the blade move in one direction, the blade will try to make the helicopter move in the opposite direction. Since the blade tries to make the helicopter spin, something is needed to keep the helicopter from spinning. So the manufacturer puts a tail rotor on the helicopter.
How does a helicopter get its lifting force?
The rotor blades relieve the air pressure from the helicopter forcing it to lift.
What happens to the advancing blade of a helicopter?
The "advancing blade" of a helicopter refers to the side of the rotor which moves forward in relation to the fuselage. As each rotor blade makes a full circle around the center, on one side of the swing, it moves forward, and on the opposite side it is moving towards the rear of the helicopter. When the helicopter is moving forward in air, the rotor blades on the advancing side are moving at a higher airspeed than the rotor blades elsewhere. Rotor speed + aircrafts forward airspeed. This results in slightly more lift on that side. Conversely the exact opposite is happening on the other side where you get Rotor speed - aircraft forward airspeed. This creates a tendency for helicopters to want to roll at high airspeed. This is one of the many odd tendencies of rotor aircraft that pilots are constantly adjusting to balance out.
The main rotor on a helicopter creates what?
the main rotor creates lift.
How do counter rotating propellers on a helicopter increase the lift?
Counter rotating blades on a helicopter are used to replace the traditional tail rotor found on most aircraft. Because the blades oppose each other (and therefore cancel out the torque created by the other blade) a tail rotor is not necessary. This allows all of the engine's power to be used for lift rather than powering the additional rotor.
What is a blade from a helicopter in words?
The main blade on a helicopter is the 'rotor'
What is palindrome for a blade of a helicopter?
rotor
What is a helicopter's spinning blade called?
A rotor.
What has a helicopter have?
It has a rotor blade instead of wings.
What is a blade of a helicopter called?
It is called the rotor.
What is a helicopter blade held on with?
Helicopter Blades are bolted onto the main rotor
What is blade pitch of a helicopter?
The angle of the rotor blades.
What is the airfoil on a helicopter?
The rotor blade is the airfoil on helicopters.
What is a rotor blade?
Rotor blades are on a helicopter. Brake rotors or discs are on the brakes of a vehicle.

What is a helicopter blade called?
the blade is called rotor bladesThe rotor blades on top are called Main Rotor Blades, because they are the main source of lift for the helicopter. The smaller rotor blades on the tail are called Tail Rotor Blades.
What is a blade from a helicopter?
It is the major part of the rotor. Helicopters can have 3 up to 8 blades on a rotor.
