Nonlinear Aeroelastic Analysis for a Rudder with a Hydraulic Booster

Abstract:

Nonlinear aeroelastic characteristics of a rudder with a hydraulic booster are investigated, including the structural nonlinearity and dynamics of the hydraulic booster. The component mode substitution method is used to establish the nonlinear governing equations based on the fundamental dynamic equations of the hydraulic booster and rocker arm. Simulations are carried out when the control command is not zero and further analysis is conducted when the freeplay angle is changed. The results show that the effects of the actuator and the structural nonlinearity have a significant influence on the flutter characteristics. In the nonlinear condition, the phase and frequency of the control command have both an influence on the flutter characteristics.
