ADVANCED
FOUR-BLADED
MAIN ROTOR
The Bell 430, a 9 to 11 place twin turbine powered helicopter, is the latest version of
Bells' well proven INTERMEDIATE TWIN helicopter series whose heritage reaches
back almost 20 years. This latest model in the series blends the attractive lines of the
222/230 family with Bells' advanced Model 680 Rotor Design.
SYSTEMS OVERVIEW
Introduction
The Bell 430 FOUR-BLADED bearingless rotor system features primary structural
elements constructed of composite materials to avoid corrosion and to provide benign,
easily detectable failure modes, along with "on-condition" (no retirement life) operation.
Main rotor blade pitch change as well as flapping and lead/lag motions occur through
flexing and bending the two composite yokes (with fluid filled dampers and shear
restraints), rather than by means of the customary hinges and lubricated bearings.
The four blades of the main rotor are of all composite construction with a replaceable
metal leading edge abrasion strip. They are designed for on-condition replacement
and are fully interchangeable. A simplified pylon support system attaches the rotor
and transmission systems to the fuselage.
