【摘要】A means for controlling a rotor of a helicopter utilizes cyclic pitch chas to its rotor blades, accomplished with a cyclic control stick. Cyclic control sticks have been a matter of concern in crashing situations. Prior art cyclic sticks are hinged to that they can be pulled out of the way of a pilot thrown forward and down by an impact. A lanyard actuated by the movement of the pilot's seat pulls the cyclic stick away from the pilot. Since such systems require various mechanisms and pulleys there is a need for an improved cyclic stick. A crashworthy cyclic control stick which is pilot actuated to overcome these difficulties is provided herein.
