A research program has been executed to evaluate candidate wing deflection measurement methods. The following two methods have been selected and flight tested: (1) an optical method based on the use of a video camera to record a black-and-white stripe pattern on the outerwing surface followed by post-flight image processing and (2) an accelerometer method based on the combined use of an accelerometer package located in the wing tip and an inertial reference system located close to the wing root. Results of these two methods are compared. The optical method performs better, Accuracies (2 values) have been achieved of 0.08 degrees in twist and 2 mm in heave at the wing tip.
