Short Discription

In this project, the new concept of so-called "hybrid blades" is being developed and numerically tested. The hybrid blades are to be used in the area of highly loaded axial compressor stages in which conventional blade geometries can no longer guarantee efficient pressure build-up. The concept of the hybrid blade is a further development of the tandem blade, which removes the weak points of the lossy end-wall flow of tandems. The hybrid blades are used both as stators and rotors in the chair's low-speed axial compressor "FRANCC" and tested numerically.

Project Targets

• Development of a fully automated process chain for the design of hybrid blades.
• 3D optimisation of hybrid blades with the aim of efficiently extending the operating range of the axial compressor.
• Gain new insights into the secondary effects of the flow within the compressor stage using different hybrid rotors and hybrid stators.
• Derive design guidelines for hybrid blades.
