What levers do on a helicopter?
They change the speed and angle of rotor, and speed of tail propeller.
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 tail rotor thrust?
Tail rotor thrust is simple the sidewards force provided by the tail rotor. This is required to offset the gyroscopic motion created by the main rotor. When the main rotor spins it creates toque in the opposite direction. The result, without a tail rotor, would be the main body of the helicopter spinning around in the opposite direction uncontrollably. The tail rotor simply provide thrust in the opposite direction to this toque and thus allows the main body of the helicopter to remain stationary. The blades of both the main rotor and the tail rotor spin at the same revs. The pilot adjusts the pedals at his feet to change the amount of sidewards thrust thrust allowing him to control his lateral movement.
Why does a typical small helicopter with a single rotor have a second small rotor on its tail?
All helicopters have a tail rotor to stabilise them.
When a helicopter tends to drift in the direction of tail rotor thrust it is called?
The tendency for a helicopter to drift in the direction of tail rotor thrust is called "Tail Rotor Drift" of "Translating Tendency".
The rotor blade on the side of the helicopter that moving in the opposite direction?
The tail rotor is moving "perpendicular" to the main rotor, not "opposite". The tail rotor creates thrust opposite to the thrust of the main rotor, to keep the fuselage from spinning. Most helicopters spin the main rotor counter-clockwise looking from above, which puts a clockwise rotation on the fuselage. You need a tail rotor pushing the tail counter-clockwise to keep the fuselage pointed in the direction the pilot chooses.
What direction does a helicopter's rotors spin?
Depending on the make of the helicopter, some will rotate clockwise and others will rotate counter-clockwise. However, the main rotor and tail rotor will spin opposite of each other. If the tail rotor spins clockwise, the main rotor will spin counter-clockwise. The main rotor also spins for lift, the tail rotor for control.
Another name for helicopter propelers?
Main rotor and tail rotor. The main rotor is on top of the helicopter consisting of two or more blades, and the tail rotor is at the back of the helicopter, which also consists of two or more blades.
Why does helicopter does not rotary about it axis?
Virtually all modern helicopters have a tail rotor which pulls against the torque that comes from the main rotor. This tail rotor also provides additional directional control assistance to the rudder. Most tail rotors turn at a 3:1 or 6:1 ratio to the main rotor. Meaning, for every revolution of the main rotor, the tail rotor makes 3 revolutions. You can read more about tail rotors here: http://en.wikipedia.org/wiki/Tail_rotor http://www.cybercom.net/~copters/mech/tail_rotors.html
Why are tail rotors perpendicular to the main rotor?
Because without a tail rotor the body of the helicopter would spin the opposite way of the main rotor so the tail rotor is perpendicular to prevent that : Way it works is the tail rotor spins at the same speed as the main rotor to over power the body's need to spin by giving just the right amount of need to go the other way : Hope I Helped , jd703
Some helicopters have on rotor on a horizontal axis perpendicular to the helicopter body at the tail Why is a single rotor never used?
because the spinning motion of the main rotor crates a force called torque, with makes the helicopter's body want to spin in the opposite direction. The tail rotor is used to create anti-torque and stop the body from spinning. In the cockpit, the pilot will use anti-torque pedals which change the angle that the tail-rotor's are spinning at. Allowing the body to spin slightly means it can change direction, and forcing it to spin more in the opposite direction allows it to turn (or yaw) the other way. A single rotor helicopter will spin uncontrollably in the air and will possibly not take off at all.
What are the main components that make up a helicopter?
Main rotor, tail rotor, drive shaft, engine and transmission, tail boom, cockpit and landing gear
