This proposal was the continuation of the already realised 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 were:

• Manufacturing and test of the already designed instrumentation;
• Optimisation (and partial redesign) of the hardware in order to reach the necessary performance and to stabilise 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);
• Optimisation 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).
