Project structure


The work plan is composed of seven work packages :

  • Five technically driven work packages (WP1-WP5), aligned on the Technology Streams (TS)
  • Support activties (Dissemination and Project management- coordination) being located in WP6 and WP7, and led respectively by L-UP and Airbus D

Highlight and most challenging task in AFLoNext:  the flight test campaign in WP1 and the large-scale wind-tunnel testing in WP2

The flight test aircraft will be the test platform for the WP1, WP3 and WP4. This allows to profit from synergies generated across the work packages through common needs for testing and shared test results.

WP1: Hybrid Laminar Flow Control

Design, manufacture, and flight test of a simplified HLFC system for the vertical tail plane (VTP) of an A320 aircraft transfer of the design principles of simplified suction to the wing, overall assessment of the benefits of the technology (fin+wing).

WP2: Active Flow Control on Airframe

Apply Active Flow Control (AFC) on the airframe in critical aerodynamic areas (engine/wing junction , outer wing) for being able to locally improve the aerodynamics (respectively to flow separation at low speeds / high angle of attacks associated with the integration of under-wing-mounted; and to allow more aggressive future wing designs with improved performance).
