Airplane Wing Flutter Boundary Optimization Using Coupled Solver Simulations
In the cruising flight regime, an aircraft wing experiences severe aerodynamic forces from all directions and above the critical speeds it initializes the flutter. Flutter phenomenon is a catastrophic one that leads to temporal (or) permanent failure of airplane structural components. To delay the flutter speed boundary or occurrences, a variety of methods have been suggested by many aeroelasticians in the past few decades. This article involves in the flutter boundary optimization using coupled solver simulations especially bending-torsion flutter. Coupling is produced by combining the Computational Fluid Dynamics (CFD) solutions and Computational Structural Dynamics (CSD) solutions with the help of a system coupling through FEA procedure. Initially, it is used to predict the flutter speed of conventional airplane wing configuration and then the analysis is extended to optimize the flutter speed through various material based properties. In specific, the relation among stresses produced on the wing is considered and it is customized to reduce the forced vibration frequency for expanding the flutter boundary. Then, the wing model is aerodynamically optimized with the help of force computations, frequencies and material properties. Numerical results are presented and verified with theoretical calculations to prove the feasibility of present methodology. This iterative design process can be revised again and again until the flutter speed boundary is converged to the optimum velocities.
