 Title:
ASSESMENT OF AEROELASTIC CHARACTERISTICS OF CANTILEVER WINGS
 
Summary :
ABSTRACT. THE PRESENT WORK DEALS WITH THE DETERMINATION OF THE AEROELASTIC CHARACTERISTICS OF CANTILEVER WINGS. THE STRUCTURAL REPRESENTATION IS MADE USING THE CLASSICAL FINITE ELEMENT METHOD OF ANALYSIS. THE AERODYNAMIC REPRESENTATION IS MADE USING THE STRIP THEORY AND THE DOUBLET-LATTICE METHOD. THE AEROELASTIC SOLUTION IS OBTAINED IN THE MODAL BASE REPRESENTATION USING THE K AND THE PK METHODS OF SOLUTION. THE RESULTS OBTAINED USING THE VARIOUS METHODS ARE DISCUSSED IN TERMS OF COMPUTATIONAL EFFICIENCY AND ACCURACY OF THE SOLUTIONS. FURTHER, THE PRESENT RESULTS ARE COMPARED WITH PREVIOUS ANALYTICAL SOLUTIONS AND WIND TUNNEL EXPERIMENTAL FINDINGS. KEY WORDS: AERELASTICITY, STRUCTURAL DYNAMICS, STRUCTURAL STABILITY
