Abstract:
Results of a study of the feasibility of employing the Moire' fringe technique in the measurement of angular displacements of practical wing structures are presented. Slope influence coefficients obtained from Moire' fringe patterns determined from a square cantilever plate and a swept wing model are compared with available theoretical and experimental data.
