3 ObjectiveTo perform simulation, testing, and validation of a conceptual Turbine-less Ducted Fan Jet Engine design.Analyze:Axial Flow PatternsPressure DifferencesThrust, Performance, and EfficiencyDesign:Outlet Nozzle
4 Background Conventional Turbine engine Air Inlet Compressor Combustion ChamberTurbineNozzle* Images from NASA – Glenn Research Center
5 Turbine-less Ducted Fan Jet Engine What is a ducted fan?A fan or compressor installed inside a ductWhy Turbine-less?No need for a turbine to drive the compressorCompressor is driven by electric motorAdvantages:Less fuel consumptionLess expensiveNot difficult to manufactureSolar panel or fuel cell for electricityHydrogen from fuel cell for combustionQuiet propulsion; suitable for undetected surveillance
