| Abstract: | An iterative computation method for nonlinear forced vibration equationon helicopter blade aerodynamic load is given. Initial load of blade is calculated by sup-posing that down-wash flow is determined, and then flapping-torsional elasticdeformation is calculated by nonlinear forced vibration equation. Each order ofharmonic load and elastic deformation of various orders in blades are calculated in thex-type helicopter computation example, the calculated results coincide with the test da-ta. |
