Flight Test Evaluation of the High Inertia Rotor System

Abstract

The objectives of this program were to document the reduction in height-velocity restrictions for autorotational landings, the increased transient performance and maneuver capability using modified flight techniques, and the handling qualities of a modified OH-58A helicopter with a High Energy Rotor System (HERS). The rotor incorporated increased chord blades and provision for three different tip weights resulting in Lock number variations of 2.61, 3. 14, and 5.43.
