Abstract

Reducing emissions and improving fuel economy has become a key target for advanced aircraft engine platforms. The competitive aviation market requires a drastic reduction in current aircraft emission levels, which leads to the requirement of optimising the entire combustion process. Lean burn pre-mixed systems are an efficient way of reducing NOx emissions. Starting from a datum blade generated in a companion paper, shape optimisation strategies applied to a fuel spray nozzle have been explored. Making use of three different design space parametrisation methods and several optimisation algorithms, an optimised passage has been generated. The optimised design achieves a considerable pressure loss reduction in comparison to the baseline design.
