Abstract

A velocity control device for controlling the velocity of a load on a flexible tension member can include a chassis with a portion of the chassis peripheral surface defining an exit aperture. The device can also include a capstan having a proximal face joined to the chassis and a distal face separated at a distance from the proximal face. A peripheral capstan surface can be tapered from a greatest diameter near the distal face to a smallest diameter near the proximal face. The device can include a throttle attached to the chassis having an interior surface defining an opening through which the tension member can pass. The interior surface is in at least partial contact with the tension member. Heat produced by kinetic energy in the flexible tension member is transferred to the throttle, and the change in system internal energy produces a drag force on the flexible tension member.
