Abstract

The present paper describes an optical deformation metrology for scientific in-flight testing which was deployed to the Airbus A320 "ATRA" of the German Aerospace Center DLR. Within the national funded LuFo-IV/3 project "High-Lift ln-Flight Validation" (HINVA) a multi-camera approach has been developed and tailored to the full-scale test bed in order to create a high fidelity wing deformation data set of dedicated dynamic and stabilized flight conditions up to maximum lift. Therefore, the wing configurations "cruise" and "landing" were measured with a variation of altitude and aircraft weight in the summer of 2012 at the Airbus facilities in Toulouse, France. The optical measurement technology is based on cross-correlation and photogrammetric principles. lt enables to derive spatial 30 deformation and deflection from virtually reconstructed surfaces. After an introduction of the project and the metrology, the specific experimental set-up is described, followed by information about the test matrix. An exemplary analysis of the wing bending and twist is presented as weil as measurement results of the trailing edge high-lift device with respective accuracy statements.
