GARDN II Projects (2014-2019)

Development of Innovative Aerodynamic Performance Enablers for Gas Turbine Engine Compressors



Focus on validating new findings in terms of axial compressor design strategies to maintain nominal performance and stall margins.

The objective of the proposed research is to validate the findings from research experimentally on a real compressor design in a representative environment to validate the predicted design improvements through testing of original designs versus a newly proposed design based on the desensitization strategies.



 In this project, partners have been able to:

  • Establish of a new design methodology for rotor with lower performance and surge margin sensitivity to tip clearance increase;
  • Design, manufacture and commission a new transonic compressor test rig that can be used in the future aerodynamic research;
  • Design, build and test the new rotor and casing treatment technologies for reducing performance and stall margin sensitivity to rotor tip clearance increase.
