title = "A high efficiency trim method for the aerodynamic analysis of xh-59a rotor in forward flight",
abstract = "The aerodynamic performance of XH-59A helicopter rotor was calculated based on Blade Element Momentum (BEM) theory under a rapid efficiency trim method in forward flight. BEM theory developed for coaxial rotor was validated by wind tunnel experiment. For the trim method, 7 control variables were involved under 6-7 constrains. The variation of shaft angle, collective pitch and cyclic pitch of both rotors with advance ratio at range 0~0.4 were compared with flight test data. It was found that except for differential lateral cyclic blade pitch, other controlled variables agree with test data in satisfied extent. As advance ratio increased, flow interaction between upper and the lower rotor was decreased, resulting in performance difference decreased.",
