Experimental Methodology and Facility for the J69-Engine Performance and Emissions Evaluation Using Jet A1 and Biodiesel Blends

摘要: Aeronautic transport is a leading energy consumer that strongly contributes to greenhouse gas emissions due significant dependency on fossil fuels. Biodiesel, substitution of conventional fuels, considered as an alternative fuel for aircrafts and power generation turbine engines. Unfortunately, experimentation has been mostly limited small scale turbines, technical challenges remain open regarding operational safety. The current study presents the facility, instrumentation, measured results experimental tests in 640 kW full-scale J69-T-25A turbojet engine, operating with blends Jet A1 oil palm biodiesel volume contents from 0% 10% at different load regimes. Findings are related injection system, engine thrust, emissions. thrust force exhaust temperature do not expose variation all operation regimes utilization up content biodiesel.
