Research on Combustion Performance of the Edge Blowing Mixture Curtain Flameholder

On the basis of elementary research,the geometry structure of the edge blowing mixture curtain (EBMC) flameholder was improved and the experimental study on the combustion performance of the EBMC flameholder was carried out in 2D afterburning test rig.The flame stability,the influence of jet velocity and fuel supply at the trail edge on the combustion performance and the performance difference between fuel supply from the frontal injector and jet curtain were analyzed.At the same time,V-gutter flameholder was used to compare with the new type flameholder.The results show that the new type flameholder is a controllable flameholder,that can work stably with higher efficiency and lower pressure loss.It is expected to be used in future aero-engine,especially its by-pass afterburner.
