Structural dynamic characteristics of a wing-engine system with gyro effects

Structural dynamic equations of a Bernoulli-Euler cantilevered beam with gyro effects were established using Hamilton principle to simulate a wing-mounted engine-wing system.The mechanism of coupling effects of rotor and structure was analyzed based on the basic theory of gyroscopic moment.The impacts of the rotor gyroscopic effect on the structural dynamic characteristics under different rotating speeds and structural parameters were analyzed.The results provided a theoretical foundation for the further study on the characteristics of a real wing-engine system and its aeroelastic performance.
