NON-DESTRUCTIVE METHOD FOR MEASURING WING BENDING AND TWISTING DURING FLIGHT

摘要

Aerospace field in particular flight testing measurement techniques. A measurement system and method and disclosed to provide qualitative information of wing bending and twisting. One difference to prior art systems and methods (see section 4) is that the present idea discloses a non-destructive flight measurement comprising optical recording (laser and optical camera) of a laser beam that is projected onto a calibrated measurement screen or small reflective array. These recordings are then subject to a post image processing technique that is used to calculate the deformation (deflection or twisting) of the wing, or other element such as a winglet.
