“…[8][9][10] CAMRAD II, along with another multibody dynamics, RCAS, was shown to predict the whirl flutter boundary of a tiltrotor. 11 CAMRAD II and Dymore showed good comparison in the study of a UAV tiltrotor in helicopter, airplane, and transition modes, as well as maneuvering. 12 CAMRAD II, Dymore, and RCAS were also shown to capture the whirl flutter trends of a tiltrotor in cruise and the proprotor loads at various pylon conversion angles.…”

“…To accurately model a sophisticated tiltrotor system, comprehensive rotorcraft analysis codes and multibody dynamics codes have been used to understand fundamental mechanisms and correlate with available test data (Refs. [17][18][19][20][21][22]. The validation of analytical methods has met with only limited success.…”

“…The failure of comprehensive rotorcraft analysis and multibody dynamics codes to consistently match each other's predictions for the WRATS (Wing and Rotor Aeroelastic Test System) model (Refs. [17][18][19][20][21][22] is a major incentive for the current effort. The WRATS is a 1/5-scale semispan aeroelastic model of the Joint Services Advanced Vertical Lift Aircraft (JVX), which evolved into the V-22 tiltrotor.…”
