عنوان انگلیسی Research on Axisymmetric Vectoring Exhaust Nozzle Dynamic Characteristics Considering Aerodynamic and Thermal Loads Effect
چکیده انگلیسی مقاله The Axisymmetric Vectoring Exhaust Nozzle (AVEN) has been extensively studied in thrust vectoring technology due to its ability to achieve 360° vector deflection. A key observation is that thermal loads are closely linked to joint clearance, which introduces significant complexity and unpredictability to the system’s dynamic response. This paper investigates the impact of thermal loads on joint forces using a finite element model. A fluid field analysis method was developed based on the operational conditions of the AVEN. The inner wall temperature obtained from this fluid analysis was then used as a boundary condition in the structural thermal analysis model. The results indicate that, for the relative angle of the joint, the combined aerodynamic and thermal loads contribute to the total aerodynamic-thermal interaction effects. Furthermore, structural stress in the steering control ring segment is primarily influenced by aerodynamic loads, while the convergence regulator ring segment is mainly affected by thermal loads.
