Title: Innovations of Robert E Head in Helicopter Technology

Introduction

Robert E Head is a notable inventor based in Palos Verdes Estates, CA (US). He has made significant contributions to helicopter technology, holding 2 patents that showcase his innovative approach to engineering.

Latest Patents

One of his latest patents is an all composite, constant speed universal joint designed for use in a shaft-driven system. This universal joint is specifically tailored for a pitch cone rotor system in helicopters. It features crossed lift beams, with one beam connected to the rotor hub and the other to the driven rotor shaft. The beams are coupled through a cruciform case, which is linked to the beams via a series of flexures made from composite fiber materials. These flexures allow for angular and translational deflections, smoothing out sudden changes in rotor speed and promoting uniform rotor speeds. Additionally, a flexible elastomeric tension link is integrated to manage rotor loads during various operational conditions.

Another significant patent involves a helicopter tail rotor utilizing an elastomerically-mounted composite flexbeam. This design incorporates a fiberglass-epoxy flexbeam that spans the length of each blade pair, effectively carrying the blade's centrifugal forces without burdening the hub. The connection between the flexbeam and the hub is facilitated by elastomeric pads, which provide a soft mount and isolate the hub from various loads, including steady driving torque and vibrations. This innovative mounting system enhances the performance and reliability of the rotor system.
