title = "Analysis of XH-59A rotor in forward fight with high efficiency trim method",
abstract = "The control and performance of XH-59A rigid rotor helicopter were investigated using high efficiency trim method based on blade element method (BET) and gradient optimization method. The accuracy of BET was validated by coaxial rotor performance prediction in wind tunnel test. The trim model was developed with 7 control variables and 6-7 constrains. The variation of shaft angle, collective pitch and cyclic pitch of the upper and lower rotor with advancing ratio were investigated. Trimmed results were compared with flight test data in advancing ratio 0.07\textasciitilde{}0.4.",
