The development of a basic technology for actively influencing the flow in the blade tip region was driven early as funding Lufo III. Based on these results, the experimental verification of selected gap topologies at a highly loaded compressor cascade shall be continued with respect to the extension of the operating range.

The project serves to improve the high-pressure compressors of future airplane engines. Starting from small blade aspect ratios (<1.0) and the new so-called "Wide-chord" blading a new blading for the NGV Dresden is designed by the partner Rolls-Royce. For this, the functionality of the already tested suction topologies must be demonstrated experimentally.

In order to be able to implement the pressure ratio and efficiency at competitive costs, weight and length required for mass application, such concepts need to find long-term input into the compressor construction. Basic research should identify concepts that make it possible to increase the aerodynamic load on the stator efficiently. Rolls-Royce Germany (RRD) will finally compile the results of the investigation in one compressor design for jet engines.
