The RSRA Active Isolation/Rotor Balance System
Abstract
The Rotor Systems Research Aircraft (RSRA) includes provisions for the installation of an Active Transmission Isolation/Rotor Loads Balance System (AIBS). The purpose of this system is to enable aircraft operation with an arbitrary rotor system over a wide rotor speed range and maneuver envelope without vibration envelope restrictions, while simultaneously providing measurement of rotor system loads. The present paper reviews the history of the design and development of this system, which culminated in successful flight test evaluation in 1977. Consideration is given to highlights of the design, ground test, and flight test.
