ADJUSTABLE HEIGHT CYCLIC CONTROL ASSEMBLY AND METHOD

摘要

Adjustable height control stick assembly for dual control of aircraft includes a single control stick for longitudinal and lateral orientation of the aircraft with the height adjustment allowing for correction of position prior to flight. The stick is connected to appropriate linkages to move the ailerons and elevator of an airplane or the rotor blades of a helicopter. When either the pilot or the copilot is flying the grip for the other is at a different height to that for normal operation. The invention replaces and makes adjustable the grip so that height of the grip of both pilot and copilot are the same as if they were flying and in control of the aircraft.

主权项

1. A height adjustable grip in a dual control aircraft movable in a lateral and longitudinal direction and having airfoil surfaces to effect lateral and longitudinal orientation of the aircraft, and wherein the aircraft is provided with side-by-side pilot and copilot seats arranged on each side of the center axis of the aircraft, the improvement comprising a single non-rotatable control stick with height adjustable mechanism for lateral and longitudinal orientation of the aircraft, said stick being located generally on the center axis of the aircraft, means forming a joint for mounting said stick for pivotal movement in a lateral and longitudinal direction, crossbar means hingedly mounted on said stick vertically above said joint whereby said crossbar is tiltable freely in a vertical plane without effecting aircraft orientation, means connected to said stick to effect movement of said airfoil surfaces for lateral and longitudinal orientation of the aircraft in response to lateral and longitudinal movement of said control stick, and spaced grip means mounted on said crossbar and, in a centered position of said control stick, being located forward of and generally centered in front of each of said seats whereby either the pilot or copilot may control lateral and longitudinal orientation of the aircraft through movement of said single control stick, where said stick has a removable grip that can be replaced by an adjustable yet similar grip, with the adjustable grip design not changing the control mechanism in any way.
