WINCH SYSTEM FOR VTOL AIRCRAFT

摘要

A winch system includes a cable storage system (34), a drive system (30) and a deployment system to deploy a cable having a hook system attached thereto. A right angle sheave (46) guides the cable between the cable storage system and the drive system. The drive system includes a dual mode transmission that provides high speed capabilities when moderate to no load is being lifted, while also providing high torque for heavy lift operations at low speeds. The deployment system is rated to support a maximum hook load and is mounted to the airframe for pivotable movement about a deployment axis to enable large cable exit angles.
