ABSTRACT

Additive manufacturing (AM) is a promising technology for producing better burners. Achieving better energy efficiency on a system level (CO2 emissions) and lower NOx, particulate emissions and CO, as directed by the International Civil Aviation Organisation (ICAO) standards, is a priority for all aircraft and aircraft engine manufacturers. At the current state-of-the-art, technologies like Powder Bed Fusion (PBF) offer a certain freedom of design one can make good use of. Instead of starting from an established conventional burner design and improve it using AM, the proposed approach in this paper is to define from scratch a design that maximises the potential benefits of AM towards a better burner. However, there are a few playing rules one must be aware of. The design, manufacturing and testing of a staged premixed burner with separate injection ramp was done as the follow-up of paper GT2018-75165 where new swirler shapes had been assessed. For this paper a monolithic, profiled burner design for premixed injection was tested for low-emission combustion. Additional features were included and assessed. Early combustion experiments are described and supported with function tests using a carefully selected instrumentation.

More specifically, the topic burner instrumentation is part of the explorative project ”rePorT” (Instrumented fuel injection ports for advanced monitoring of the injection in the combustor of an aeroengine, contract 850454, CBOne stand-alone).

The burner design is part of the collaborative research ”emootion” (Engine health monitoring and refined combustion control based on optical diagnostic techniques embedded in the combustor, contract 861004, consortium CBOne + FH Joanneum / Aviation) - both projects were done within the ”Take-Off” programme.

The activities specific to additive manufacturing are part of a pilot study on burner manufacturing using PBF (contract 862837, consortium CBOne + Joanneum Research GmbH / Materials).
