Title:
|
A HYBRID METHOD FOR AEROELASTIC ANALYSIS IN TRANSONIC FLOW
|
| |
|
Summary :
|
|
AEROELASTIC ANALYSES OF A FIGHTER AIRCRAFT AND OF THE STANDARD AEROELASTIC WING AGARD 445.6 IN TRANSONIC FLOW ARE PRESENTED. THE ANALYSES WERE PERFORMED USING A FINITE ELEMENT MODEL AND A MODAL MODEL RESPECTIVELY. THE DOUBLET-LATTICE BASED MODULE IN NASTRAN(TM) WAS USED WITH AERODYNAMIC INFLUENCE COEFFICIENTS MODIFIED FOR TRANSONIC FLOW ANALYSIS. THE AERODYNAMIC MODIFICATION WAS BASED ON RESULTS FROM A FINITE-DIFFERENCE NAVIER-STOKES SIMULATION OF FLOW AROUND THE WINGS IN TRANSONIC FLOW. |
