Abstract
The certification of the Leonardo Helicopters AW609 tiltrotor includes certifying, for the first time, the tiltrotor drive train architecture in a civilian aircraft. This paper presents a Simulink-based linear analysis that predicts torsional stability across the flight envelope as well as sensitivity to important design parameters. The paper also describes the ground and flight-test methodology carried out in the certification test campaign. The post-processing of experimental data is summarized, and results from the certification test campaign are presented as model correlation.
