Abstract
Abstract An air combat control head with an extension provides a head for a collece control stick wherein system control switches may be located for easy access by the operator and an extension comprising a phenolic coated hand grip and a bottom tube component. The hand grip is offset laterally and longitudinally from the bottom tube component, and the head is canted back toward the operator, making the system control switches workable by the operator's thumb while the rest of the operator's hand grips the stick and maintains control of the collective pitch of the main rotor blades. The collective control head of the invention provides a controller that is comfortable for an operator to use, even in extended flight operations, and that reduces fatigue, discomfort and distraction while making system control operations easy and effective.

Claim 1
Independent Claim
138 words
A control head which imparts control signals to a propulsion means of a vehicle, said control head comprising a root end tube member connected to means for controlling the propulsion means; a concentric tube portion mounted fixedly to the root end tube member; a phenolic coated handgrip having contoured indentations conforming generally to the shape of the palm and thumb of a human hand and mounted fixedly on the concentric tube portion, said handgrip being offset laterally in the range of 10° to 20° and longitudinally in the range of 8° to 12° from said tube portion; a head member, having its upper portion canted back toward an operator and being integral with the handgrip, said head member containing auxiliary system actuation means; and means for transmitting electrical impulses from the actuation means to their respective auxiliary systems.
Claim 2
Dependent Claim
138 words
A control head which imparts control signals to a propulsion means of a vehicle, said control head comprising a root end tube member connected to means for controlling the propulsion means; a concentric tube portion mounted fixedly to the root end tube member; a phenolic coated handgrip having contoured indentations conforming generally to the shape of the palm and thumb of a human hand and mounted fixedly on the concentric tube portion, said handgrip being offset laterally in the range of 10° to 20° and longitudinally in the range of 8° to 12° from said tube portion; a head member, having its upper portion canted back toward an operator and being integral with the handgrip, said head member containing auxiliary system actuation means; and means for transmitting electrical impulses from the actuation means to their respective auxiliary systems.
