What is the control stick in a helicopter called?
cyclic stick
The cyclic control, commonly called the cyclic stick or just cyclic, is similar in appearance on most helicopters to a control stick from a conventional aircraft. The cyclic stick commonly rises up from beneath the front of each pilot’s seat.
What is the purpose of swashplate?
A swashplate is a device that translates input via the helicopter flight controls into motion of the main rotor blades. Because the main rotor blades are spinning, the swashplate is used to transmit three of the pilot’s commands from the non-rotating fuselage to the rotating rotor hub and mainblades.
What does the collective pitch control do?
The collective pitch control (or simply “collective” or “thrust lever”) is located on the left side of the pilot’s seat and is operated with the left hand. The collective is used to make changes to the pitch angle of the main rotor blades and does this simultaneously, or collectively, as the name implies.
What is yaw in helicopter?
As you may know, yaw is the ability of a vehicle to rotate from left to right. As the rotor spins clockwise at a high rate of speed, there is an equal and opposite reaction acting on the helicopter fuselage making it want to spin counterclockwise.
What are the rotating and non-rotating swashplate connected to?
Connecting the rotating swash plate to the rotor shaft is an assembly known as the drive link. The swash plate has a rotating and non-rotating side. The non-rotating side is on the bottom and is connected to the flight controls. The rotating side is on the top and is connected via pitch links to each rotor blade.
What is the difference between cyclic pitch and collective pitch?
Cyclic pitch is the individual angling of the blades on each revolution of the rotor. This affects the roll of the craft, moving the nose upward or downward or rolling the craft from side to side. Collective pitch is the angling of all blades by an equal amount in unison.
How do RC helicopters pitch?
Fixed Pitch RC Helicopters. The pitch of the main rotor blades are held at a fixed or constant angle of attack. You control the amount of lift to your helicopter by simply varying the speed of the engine/motor. If you increase the speed of the motor, the rotor blades turn faster and produce more lift.
What is pitch and yaw in helicopter?
Imagine three lines running through an airplane and intersecting at right angles at the airplane’s center of gravity. Rotation around the front-to-back axis is called roll. Rotation around the side-to-side axis is called pitch. Rotation around the vertical axis is called yaw.
What is pitch RC helicopter?
RC Helicopters are becoming so popular that it attracts many new enthusiasts everyday. The “pitch” of a helicopter is the angle of the main rotor blade. Generally, the measurement of this “pitch” angle is done relative to the horizontal plane. Helicopters generate lift by rotating their rotor through the air.
How does the attribute pitch work in a car?
The attribute pitch can be referred to bouncing a ball. In the car case, it is a different scene. Imagine driving in a metal rod into the side of a car such that it protrudes through a car from both horizontal ends. Now, if that rod is rotated clockwise or anticlockwise, the car will also rotate with that rod.
How is pitch control used in a helicopter?
When flying a helicopter, the pilot is continuously controlling 2 important parameters: the amount of thrust, which is achieved by changing the pitch of all of the blades simultaneously, also known as collective pitch control; and secondly, the direction in which the rotordisc is tilted.
How does pitch control work on a blade?
The collective control works by sliding the swashplate up and down. This movement will change the pitch of all of the blades simultaneously and by the same amount. Cyclic control tilts the swashplate, thereby changing the pitch of each blade continuously through each blade revolution.
How is the pitch of a propeller controlled?
The propeller blades all rotate together until the feedback signal balances the demand signal and the low pressure oil to the auxiliary servo motor is cut off. To enable emergency control of propeller pitch in the event of loss of power the spool valves can be operated by hand.
