The rudder structure of civil aircraft is usually located at the rear of the vertical tail, which is connected with the trailing edge of the vertical stabilizer through the connecting hinges, and is driven to deflect by the actuators to provide the yaw moment. The airworthiness requirements of civil aircraft rudder bird strike were analyzed, and the specific requirements of rudder bird strike resistance were defined. After the completion of the above work, the bird impact performance of a certain type of civil aircraft rudder was comprehensively evaluated. Through the engineering algorithm, the bird impact force under different rudder angles of a civil aircraft was preliminarily evaluated firstly, and the severe conditions of bird strike were screened out based on the results, which avoided the calculation of bird strike under different rudder deflection angles, thus greatly reducing the workload of simulation analysis. Through SPH method, the bird strike analysis of rudder structure was carried out by PAM-Crash software, and the damage condition of rudder wing surface structure, load condition of connecting hinges and rudder actuators were obtained. Based on this, a complete evaluation of rudder’s bird strike resistance was completed.
