This proposal is the continuation of the already realized Reflectometry and Shadow Casting work from the first part of the CleanSky/BLADE Program for the in-flight measurement of local wing surface deformations.The main aims are:• Manufacturing and test of the already designed instrumentation.• Optimization (and partial redesign) of the hardware in order to reach the necessary performance and to stabilize these performances.• Implementation of a local topographic wing marking that has no negative influence on the laminar air flow (fluorescent markings 5 to 10µm thickness).• Optimization of the already designed software (stability, illumination tolerance, vibration tolerance, integration of the markings, compliance with wing convexity, compliance with bending and torsion of the wing at changing load).• Support during integration of the instrumentation in the aircraft.• Calibration before flight.• Fine tuning of hard- and software for difficulties during the flight campaign.• Development and full implementation of an on-board real-time data processing/analysis tool for first diagnostic during the flight.• Design and manufacturing of the ground station for differed time data processing/analysis.• Supply of the necessary consumables (SSD mobile drives) for Data transfer between Cabin computer and ground station (evaluation and analysis)
