The project activities are divided in six work packages:
- WP1: Management: Administrative and financial coordination of the project.
- WP2: Concept Analysis: Exploration and systematic assessment of the most important parameters involved in the accuracy and robustness of pressure and load determination procedures; what are the different key elements in the “measurement chain” and how do they influence the end result; requirements on the temporal and spatial resolution; extension to compressible flow conditions; theoretical analysis by means of synthetic experiments and CFD simulations. With the feasibility of the basic principles confirmed in previous works, a specific focus of attention will be on alternative, innovative approaches.
- WP3: Experimental Validation: The objective of this WP is to test and assess the performance experimentally in well-controlled conditions. This will involve the investigation of generic unsteady and/or turbulent flow structures, which are challenging as one has to deal with a large range of flow (time and length) scales, which sets specific high demands on the resolution and dynamic range capabilities of the method; validation against surface pressure sensors and PSP.
- WP4: Applications I: unsteady wing aerodynamics: The unsteady aerodynamics of moving, flapping and/or deforming, flexible wings is receiving increased attention in the recent years, not in the least motivated by the development of small-scale Micro Aerial Vehicles (MAVs). In the aerodynamic analysis of the associated flow phenomena, the non-intrusive pressure and loads determination methods provide a convenient way to extract these data (often very small forces are involved) and relate them to the observed flow and wing-deformation phenomena. Four different experiments on 3D and flexible wing configurations are investigated by different partners.
- WP5: Applications II: high-speed flight: For the high-speed flow regime some progress has been reported for pressure evaluation from PIV data, be it under restrictive conditions. The restrictions involved are related to the measurement conditions associated to PIV in high-speed flow (time resolution, limited optical access), as well as including the effect of variable density in the pressure and load determination. Two experiments for high-speed flow are conducted: (1) an airfoil under transonic conditions and (2) a generic launcher-afterbody wake flow.
- WP6: Dissemination: The specific actions undertaken for knowledge
dissemination include in particular the organisation of four international workshops during the second half of the project duration, as well as a Closure Symposium with invited industrial partners. The special purpose of these events is to bring representatives of R&D sections from the aerospace industrial research community in close contact with the overall achievements of the project and promote the utilization of results with possible pilot experiments and demonstrations.
