Comprehensive Aeroelasticity Analysis on New Hingeless Rotor Using Fully Intrinsic Equations

Wang Bo;Liu Yong;National Key Laboratory of Science and Technology on Rotorcraft Aeromechanics,Nanjing University of Aeronautics & Astronautics;95507 Army,Chinese People′s Liberation Army;  
For the geometric nonlinear of large deformation and the characteristics of root multi-channel force transmission,the fully intrinsic equations are established for comprehensive aeroelasticity analysis of hingeless rotor considering the unsteady dynamic load.To solve the coupling problem of rotor dynamics and airdynamics,the high accuracy Galerkin variable-order finite element is developed with the use of Newmark average velocity method and Newton relaxation iteration method.The method not only accurately simulates the conditions of root multi-channel force transmission of new hingeless rotor,but also has good accuracy in the static aeroelasticity response,the vibration load and the calculation of the aeroelasticity stability.
