摘要: When a scaled flutter model is designed for aeroelastic experiment in a specific wind tunnel, the size of it was recognized to be installed within the rhomboid zone. This paper discussed the influence of the rhomboid zone of a wind tunnel on aeroelastic experiment for supersonic aircraft. Three sizes of flutter models of a same aircraft structure were modelled with structure-similarity and the exceed range outside the rhomboid of them were different. Aerodynamic force and Flow distributions around the three models were predicted with engineering algorithm and CFD method. Detached eddy simulation, which can obtain a good balance between calculated expense and accuracy, was adopted for three dimensional turbulence computation. Then their aeroelastic characteristic were compared. It was found from the compared results that when the model size exceed a range, flow distribution can provide a significant influence on the experimental results for a flutter model of supersonic aircraft. Inversely, the influence can be neglected if the exceed range do not cause serious changes of flow distribution around the model.
