AbstractThe development of a commercially viable photogrammetric system is proposed for measurement of motion and deformation of flight control surfaces. This system will measure the position, velocity and deformation of flight control surfaces in an aircraft where such deformation typically includes bending and twist of these surfaces produced by aerodynamic forces. The Phase I effort focuses on performing a feasibility study of the proposed technique and demonstrating a prototype system. A follow-on Phase II effort would culminate with a working commercial system which will be validated in appropriate wind tunnel and/or flight tests. The significance of such a system is that it provides accurate, non-contact measurements of motion, as well as deformation of a flight control surface using digital photogrammetry. In Phase II, the system will also be enhanced to determine the stresses on flight control surfaces, based on motion and deformation measurements. This innovative system will be robust and easy-to-use, and suitable for a variety of aircrafts.
