Exploratory investigation of combustion and nvh emissions signature of a drone jet engine fueled with ipk

The pollution from aerospace transportation is rapidly becoming the largest source of greenhouse gas (GHG) emissions. The FAA expects aviation emissions to almost triple by 2050, making the aerospace industry responsible for the release of approximately 25% of the global carbon dioxide budget. These aviation emissions, including CO₂ and NO_x, as well as other GHGs, contribute to the destruction of ozone layer. Carbon dioxide emissions have a particularly negative effect on humans, leading to airway diseases especially in children and elderly. To combat the addition of further GHG emissions into the atmosphere, it is necessary to increase engine efficiency while reducing the NVH signature. Synthetic kerosene has a high potential for both commercial and military use due to their low soot emissions and their favorable balance of fuel properties. The purpose of this study is to investigate combustion, emissions and NVH produced by combustion of synthetic kerosene (IPK) in a drone single stage gas turbine. Electronic data acquisition systems, including microphones, accelerometers, load cells, Mie scattering for sprays characterization, a constant volume combustion chamber (CVCC) and a state of art FTIR emissions analyzer were employed to during this project on the IPK and the jet engine.
