  2. Nondisclosure Agreement • Certain design aspectsare subject to a non-disclosure agreement. Please respect that some questions may not be fully explained due to this agreement.

  3. SpinDyne Rotary Steam (RS) Engine

  4. Engine Analysis Method Steam state entering engine (i) Known Known Steam state exiting engine (f) mi=mf, where m=V/v

  5. Engine Results *The red font represents the nominal operating conditions that were to be tested, 800 psi and 718°F (entering the engine conditions)

  6. Condenser and Pump • Use of SteamTab and Matlab to find inlet and exit conditions • Found minimum heat rejection needed for each pressure

  7. Metal Foam • The metal foam helps increase heat transfer out of the system to conserve internal energy. • The idea is no longer feasible due to costliness • While a metal foam condenser foam would work, the price for having ERG Aerospace due an analysis to find a size was estimated to be around $8,000 • The prototype would cost even more • The cost does justify the amount of work that has to be done to build a working prototype

  8. Feed Water Pump • Feed water pump used to increase the pressure of the water leaving the condenser and return the water to the boiler. • Ideal Model: Pump analysis assumes reversible adiabatic compression process. • Through our model of the pump • Inlet State: 178.36F , 7.25psia • Exit State: 180.43F , 800psia • Pump Power Required: 0.408HP

  9. Pump Cavitation • Pump Inlet State • Pressure 7.25psia, Temperature: 178.36F • Vaporization Pressure: 7.2psia (178.36F) • Pump Cavitation • Degrades pump performance • Destructive to internal components • Buffer Tank • Provide Additional Head to the Pump

  10. Pump Cavitation

  11. Boiler requirements • Heat transfer rate Required Qdot =148.55 kW • Nominal Temperature and pressure entering the engine @ 718 ˚F and 800 psi

  12. Calcium Silicate pipe insulation • temperatures 1200 ˚F • Flame retardant • Rigid and durable • Low thermal conductivity

  13. Combustion

  14. Combustion Raw Data Combustion Thermal Efficiencies

  15. Combustion Final Ranking

  16. Finite Element Analysis • High displacement areas are noted in red • A maximum deflection of 0.0005 in • Material Stainless Steel • Rotor is 4 in thick

  17. IC engines in productionDD13 Detroit Cummins QSK78 Volvo Penta

  18. Exploded View

  19. Engine comparison SpindYNE DD13 V-12 Detroit

  20. Conclusion: Is the RS engine feasible • SpinDyne’s current design is not feasible as of now, to replace the internal combustion engine. SpinDyne’s current design of dual cores will not produce enough power or torque to create sustainable vehicular propulsion • It lacks engine performance • Would need about 6 cores to match the horsepower/torque of a tractor trailer engine which not only creates a size issue but cost increase • Cost • Space-age materialsand new manufacturing process

  21. Conclusion: • This engine is currently not a viable option to replace the IC engine but is capable of being a power source in various industries • Further advances in manufacturing processes and material sciences in the future might allow this engine to be feasible
