ABSTRACT:
A payout sheave for a cable connecting an underwater transducer array or instrumentation package to processing and display equipment directs the cable as it is payed out and in toward a reel and level wind mechanism carried in a platform vehicle such as a boat or helicopter. The supporting frame for the sheave includes a cross member supported along a first axis in bearings in the frame and which carries additional bearings at its center. These center bearings carry an intermediate support structure which is rotatable thereon along a second axis perpendicular to the axis of the cross member. This intermediate support structure carries a pair of journals and bearings oriented along a third axis perpendicular to each of the first and second axes. A fork member is attached to the intermediate support structure through the bearings, and the sheave is carried in the bifurcated section of this member and thus, in effect, is gimbaled for movement along all three axes. A first rotary linear transformer is mounted on the frame such that its rotor moves with the cross member, and a second such transformer is carried on the intermediate support structure with its rotor responsive to movement of the fork member relative to the intermediate support member. These rotary linear transformers each provide electrical output signals varying with the departure of the cable from a null position with respect to the first and third axes, and such signals are used in a navigation or autopilot system for the platform vehicle. A second embodiment provides for movement along the described three axes through the use of a monoball structure carried on a journaled cross member with the fork carried on its monoball and the electrical position signals being supplied by a lamp mounted on the fork which moves its beam over the surface of a two-axis photocell. The output of the photocell varies with the direction and extent of departure of the beam from a null position.
