WP 1 is the overall management work package to cope with all the relevant topics in co-ordinating the project, organising the general meetings and disseminate the gathered knowledge by creating a communication platform. Furthermore it is designated to take care of gender issues. The WP 1 does continue for the complete project duration of 42 months.

WP 2 concerns deformation measurements on wings and control surfaces and mainly deals with the improvement of IPCT and marker based optical deformation techniques for measuring wing and control surface deformations in flight. A step-by-step approach is affiliating the development. In the first step of WP 2 the IPCT and the marker techniques are improved towards easy and accurate measurements of wing and control surface deformations. In the second step the improved measurement setups are tested and optimised during tests on research aircraft. In the third step the optimised setup are tested under industrial conditions. The WP 2 did start with the AIM² project and will end in month 36.

WP 3 is devoted to improve IPCT and Marker based techniques for propeller deformation measurements and therefore to develop a QVT setup for 360° propeller deformation measurements. Like in WP 2 a gradually approach is followed for the improvement of installation, calibration and post-processing, the ground testing of the developed setup and a flight test demonstration under industrial boundary conditions. The WP 3 has started with the AIM² project and will end in month 36.

WP 4 expedites the improvement of FBG for surface pressure measurements and the development of unsteady IRT for transition and shock detection. In a step-by-step approach both techniques firstly are further developed in the laboratory, afterwards research flight tests with FBG and unsteady IRT will take place. A feasibility study of the usage of IR mirror techniques for IRT is also be included. The WP 4 has started with the AIM² project and will end with month 36.

In WP 5 further developments to enhance the optical measurement methods PIV and BOS for in-flight flow field measurements are conducted and standard calibration procedures as well as airspeed measurement based on LIDAR methods will be improved. In a stepwise approach laboratory level measurement setups shall be transferred and adapted to different aircraft types and industrial applications. The WP 5 has started with the AIM² project. The PIV and BOS activities are scheduled to be finished in the 36th month. The LIDAR activities will finally end with month 42.

WP 6 condenses WPs 2 to 5 and is used to selectively review the tested techniques as well as to create useful tools and guides for an easy application of these techniques by non-experienced users. Furthermore the WP 6 serves the promotion of the advanced in-flight measurement techniques. In detail WP 6 mainly deals with the creation of an application matrix and a toolbox for the measurement techniques developed in the AIM² project. The application matrix and the toolbox are promoted during a flight test workshop and will be utilised during several industrial measurement tasks. Parts of the final task report of WP 6 will constitute an easy-to-use guide for “non-experienced” users to apply optical measurement techniques to flight tests. The WP 6 has also started with the AIM² project and within its first step it is devoted to the conveyance of knowledge from the other WPs 2 to 5. The second step is the tailoring of the tools and their application. WP 6 will end in the 42nd month of the project.
