  1. Jet Turbine Design & Analysis by Evan Lane

  2. Jet Turbine Project • Scope • Design an inexpensive, self-sustaining jet turbine • Construct the turbine according to design specifications • Analyze the turbine’s performance (if it runs) • Class Goals: • Demonstrate knowledge of thermodynamic power cycles • Give you all an exciting demonstration • Provide construction plans (time permitting)

  3. Jet Turbine Project • Personal Goals • Solidify my knowledge of thermodynamics through a practical project • Practice manual & CNC machining skills to get repeatable tolerances of ±.002” • Get to say, “Yeah, I built a jet engine. No biggie.” • Risks & Challenges • Construction timeline • Propane safety • Simplification of fluid flow analysis to fit thermodynamics course scope

  4. Ideal Assumptions(Assumes: air modelled as ideal gas, mass flow due to fuel is negligible)

  5. Design • Enclosure • SCH80 steel pipe enclosure (free) • 2.38” OD • 1.94” ID • Combustor • 24 gauge sheet steel • .125” brass gas inlet • #4 glow plug (“hot” rating) • Compressor & Turbine • Mitsubishi centrifugal compressor: MHI TD04-09B • 16 gauge sheet steel turbine • 10 mm ground steel shaft • 10 mm ID shielded ball bearing: 61800 2RS (from another project) • 10.5 mm ID oilite journal bearing • 5 mm ID oilite thrust bearing

  6. Design • Inlet • Whatever cheap aluminum block I can find lying around (maybe 6061 or 5205) • CNC machined to maintain .03125” clearance with compressor blades • Diffuser • .1875” aluminum sheet • Two parts to simplify machining process • Nozzle • 16 gauge sheet steel • Moveable vanes to allow for adjusting exit velocity and backpressure

  7. Important Variables • Pressure ratio across compressor • Determines temperature ratio across compressor • Temperature at turbine inlet • Relates temperature rise for compressor and turbine • Speed of sound • Important factor in determining thrust • Thrust • Sought after value

  8. Progress • Calculations completed for: • Combustor • Fuel inlet • Parts purchased/ acquired for: • Body • Compressor • Shaft • Bearings • Fuel line • Diffuser

  9. Progress • Parts designed: • All • Parts machined/ completed: • Diffuser • Compressor • Body
