Heavy Lift Helicopter - Advanced Technology Component Program - Hub and Upper Controls

Abstract

The Heavy Lift Helicopter Advanced Technology Component (ATC) development program was conducted by the Boeing Vertol Company for the U.S. Army from July 1971 through July 1975. As a part of this program, an advanced rotor hub and upper controls system design was developed and demonstrated to be satisfactory for application to the XCH-62 Prototype HLH. The ATC hub and upper control component development/demonstration activities included the flap/lag pitch elastomeric bearing, frequency selective lag damper, and shear bearing development efforts; manufacturing techniques development; fretting inhibitor evaluation; safe-life, fail-safe, and endurance testing of major hub and upper control components; whirl tower tests; and integrated rotor-drive system tests.
