Background & Policy context

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.


The VerDeMod project focused on 4 objectives to be achieved during the project:

  • Increase the efficiency of levels with adjustable guide vanes.
  • Reduction of efficiency losses at fixed guide vanes.
  • Optimization of the annulus thanks to non-axisymmetrically construction of the casing
  • Identify and measure the impact of the flow unsteadiness

The VerDeMod project is divided into 4 work packages:

  • WP1: project management
  • WP2: Development of innovative design tools
  • WP3: Performance optimization of the annulus
  • WP4: Exploitation of flow-unsteadiness phenomena

According to the different subprojects, the following results have been achieved:

  • WP1: project management: The project coordinator was responsible for the efficient usage of the resources and the compliance of the timetable. Furthermore, the subcontractors (Universities of Braunschweig, Darmstadt and Dresden, DLR Köln and AneCom Aerotest) were coordinated.
  • WP2: Development of innovative design tools: An optimization regarding the gap of the adjustable guide vanes was successful. Furthermore, a blade-internal air absorber and a robust design tool were developed.
  • WP3: Performance optimization of the annulus: Numerical development of special components for the high pressure compressor, and validation of the findings.
  • WP4: Exploitation of flow-unsteadiness phenomena: The project partners were able to validate numerical calculation methods for models with respect to flow unsteadiness.

Findings of the study are published by a final report (German only), which is available online via the Technical Information Library (TIB) of the Hannover University:
