Project objective

The objective of the present proposal is to perform in-flight, time-resolved measurements of skin friction and surface pressure near the wing-pylon interface of a transport aircraft approaching stall. This research is driven by the need to integrate Ultra High Bypass Ratio (UHBR) engines on the wings of transport aircrafts. Such UBHR engines, which have a higher propulsion efficiency than current models and thus contribute to a more ecologic and economic aircraft-engine platform, are associated with relatively large nacelles that increase the risk of flow separation on the wing/pylon interface. In order to mitigate this risk, active flow-control technologies are required. The development of these technologies requires, in turn, the accurate measurement of skin friction and surface pressure.

The approach proposed herein is (1) to design and fabricate a complete, flight-ready, measurement system based on hot-film sensors for skin-friction measurements and fiber-optic sensors for pressure sensing, (2) to validate the system during preliminary wind-tunnel and low-speed flight experiments, and (3) to perform the actual flight measurements near the wing/pylon interface of a transport aircraft. Within the Cleansky 2 JTI, the results obtained in this project will be used to demonstrate and quantify the effect of active flow-control in the region of the upper-surface wing near the wing-pylon interface.

The major impact of this project will be to contribute to the expected impact of the Clean Sky 2 Work Plan by permitting the experimental validation of local active flow-control near the wing-pylon interface of a transport aircraft. In addition, this project will enable further progress in innovative aerodynamic clean technologies for air transport and ultimately lower the environmental impact of commercial aviation while contributing to an increased European competitiveness in aeronautics.
