Abstract:

Some results of aeroelastic tailoring of a sweptback wing with medium aspect ratio and composite skin and metal frame are presented. By use of Tsai-Hill criterion the strength critical elements were resized. Then the flutter or aileron effectiveness critical elements were redesingned by use of the uniform-flutter velocity or uniform-aileron effectiveness derivative criteria. By a few steps of resizing, satisfactory results are obtained.

Key words: aeroelastic tailoring, composite structure, flutter, divergence
