Abstract:

A complete understanding of the factors which establish the flight envelope of a helicopter requires simultaneous consideration of power, static and dynamic stability, handling qualities, and pilot techniques as well as resulting loads and vibration levels. To facilitate this understanding, an interdisciplinary mathematical model that provides analytical prediction of free-flight characteristics of single-rotor helicopter and compound helicopter configurations has been developed. The work described in this report presents a loads correlation of the current REXOR II program with existing AH-56A and XH- 51A compound test data with primary focus on steady and cyclic loads during steady and transient maneuvers.
