Authors Abstract
Content
An isolation system has been developed for hingeless rotor helicopters which has been demonstrated to be extremely effective in preventing rotor induced vibration from reaching the airframe. Named IRIS (Improved Rotor Isolation System) the system has been in development for 3 years and was first flown and is currently being demonstrated on a BO-105 helicopter. A similar system has been installed in a Company-owned UTTAS helicopter and is presently being developed through flight testing.
This paper describes some of the analytical and bench testing background of both IRIS installations and presents latest available flight data.
