Research of Reynolds stress model in the aerodynamics of damping rings aircraft

Airflow disturbance affected aerodynamics of aircraft between damping rings. In order to simulate this disturbance, extra-fluent field of damping rings aircraft was analyzed by Reynolds stress model (LLR-QI) in this paper. Numerical simulations results indicate that spaces between damping rings affected drag coefficient, and keep to test results, to based on improving firing accuracy of the aircraft.
