Aerodynamic characteristics analysis of civil airliner nose and main landing gear systems
Abstract
This study establishes a high-fidelity CFD model using the k-omega Shear Stress Transport (SST) turbulence model to evaluate the aerodynamic characteristics of civil aircraft nose and main landing gears across four speed conditions. The results indicate that both landing gear systems exhibit similar surface pressure distributions across different speed conditions. Furthermore, the magnitude of aerodynamic forces increases proportionally with the incoming flow velocity. Significantly, the shock struts of both landing gear systems emerge as major contributors to the overall aerodynamic drag. It is also found that aerodynamic lift remains relatively low compared to both aerodynamic drag and side forces.
