- AFLoNext is a project of four years duration, funded by the European Commission within the Seventh Framework Programme. The project’s main objectives are proving and maturing highly promising flow control and noise reduction technologies for novel aircraft configurations, to achieve a big step forward towards improved aircraft performance and thus reducing the environmental footprint. The project consortium is composed by 40 European partners from 15 countries. One of the six technology streams, which are forming the scientific concept of AFLoNext, is concerned with the mitigation and control of vibrations in the undercarriage area during take-off and landing. Structural components in the vicinity of the landing gears, e.g. undercarriage housing walls, struts or landing gear doors, are often subject to significant dynamic loading. These loads originate from fluctuating aerodynamic pressures and resulting structural vibrations. Unsteady pressures on structural parts are caused by highly fluctuating and complex aerodynamic flow behavior under the fuselage. The paper describes the CFD approach employed to predict such dynamic loads and presents some preliminary results that have been computed with hybrid RANS-LES models and the Lattice Bolzmann method. Several vibration control devices have been proposed and are discussed in the paper. Some of these devices will be installed in the near future on the DLR Airbus 320 ATRA (Advanced Technology Research Aircraft) to perform flight tests to and to measure dynamic loads.
