Helicopter cyclic from roof.

The combination of cyclic feathering and blade flapping compensate for the dissymmetry of lift across the rotor disc due to wind or airspeed. The control for changing the pitch of each rotor blade individually as it rotates through one cycle to govern the tilt of the rotor disc and. Raising or lowering the pitch control increases or decreases the pitch angle on all blades by the same amount. This causes the helicopter to move in the direction that the cyclic is moved.

Cyclic pitch lever a helicopter pilot controls the pitch or angle of the rotor blades with two inputs. As stated the foot pedals control the pitch of the tail rotor blades thereby balancing main rotor torque. This video is intended to be used in conjunction with a home recreational flight simulation. A helicopter has four controls.

The cyclic or stick comes out of the floor of the cockpit and sits between the pilot s legs enabling a person to tilt the craft to either side or forward and backward. With your right hand you ll operate the cyclic control which is similar to a joystick. Animation showing how the cyclic changes the rotor disk angle. The two lateral inputs are across from each other and create a pivot axis perpendicular to the single fore and aft input.

The cyclic and collective pitch levers often just shortened to the cyclic and the collective. Push the cyclic forward to move forward back to move back and to either side to move sideways. It is a lever that moves up and down to change the pitch angle of the main rotor blades. The collective pitch control is usually found at the pilot s left hand.

That feedback into the cyclic channel is a result of how most flight control linkages attach to the swashplate. Other helicopter aerodynamic. The cyclic is the control stick located between the pilot s legs. Changes to the aircraft flight control system transmit mechanically to the rotor producing aerodynamic effects on the rotor blades that make the helicopter move in a deliberate way.

The control is called the cyclic because it can vary the pitch of the rotor blades throughout each revolution of the main rotor system i e through each cycle of rotation to develop unequal lift thrust. To fly a helicopter your left hand will operate the collective control which changes the main rotor s blade angle. 89 fm 3 04 203 2007 fundamentals of flight pg. Collective pitch control throttle control antitorque control and cyclic pitch control.

A helicopter pilot manipulates the helicopter flight controls to achieve and maintain controlled aerodynamic flight. Consequently the direction and velocity of horizontal movement. Although the robinson r 22 and r 44 have a unique teetering bar cyclic control system and a few helicopters have a cyclic control that descends into the cockpit from overhead. Raise the collective to make the helicopter rise and lower it to make it go down.

It can be moved in any direction to tilt the plane of rotation of the rotor blades. Faa h 8083 21a helicopter flying handbook pg.
