    Abstract
  • Fluid structure coupling method based on three dimensional Reynolds average Navier-Stockes (RANS) equations and static equation was used for study on aerodynamic characteristics of the civil aircraft with powered effects. Firstly, numerical calculation was adopted to simulate the boundary condition of the fan-inlet and jet-exhaust and analyze the flow field of the turbine powered simulator. The numerical results agreed well with those from the wind tunnel experiment. Furthermore, the research on the performance of the aerodynamic characteristics of the aircraft with powered nacelle and with flow-through nacelle was conducted through computational fluid dynamics（CFD）/computational structure dynamics (CSD) approach. The numerical results indicate that the aerodynamic performances such as lift coefficient, drag coefficient, aerodynamic loads and pressure center location based on powered nacelles differ obviously from flow-through ones. Elastic effect can increase the differences so that it can make lift-drag ratio decrease by approximately 12.6%, lift coefficient decrease by 8.9%, and pressure center location move backwards. The numerical example showed that the aerodynamic loads close to the nacelles were influenced notably by powered effects while those far from the nacelles were affected mainly by the elastic effects. Consequently, it is necessary to consider the elastic effects when analyzing civil aircraft aerodynamic characteristics.
