Abstract :
This paper illustrates results of a series of deformation measurements on a dummy wing which were performed in the NLR workshop. Two different Moire techniques are applied: the Painted Pattern Method, and the Projected Pattern Method. The out-of-plane distortions, obtained under applied different loads, are compared with those measured in five sections along the wing span using a 3D Co-ordinate Measuring Machine and with those predicted using a CAD system. Two examples of wind tunnel measurements are briefly discussed
