CONCLUSIONS </li></ul>
  3. 3. <ul><li>What is stirling engine? </li></ul><ul><ul><li>It is a heat engine operating by the cylic compression and expansion of gas </li></ul></ul><ul><ul><li>The process occurs at various </li></ul></ul><ul><ul><ul><li>temperature levels </li></ul></ul></ul><ul><ul><li>Net conversion of heat energy </li></ul></ul><ul><ul><ul><li>to mechanical energy </li></ul></ul></ul><ul><ul><li>Mechanical energy electrical energy </li></ul></ul>
  4. 4. <ul><li>Plutonium -238 fuel </li></ul><ul><ul><li>(generates the heat) </li></ul></ul><ul><li>Cladding </li></ul><ul><ul><li>(encases the fuel) </li></ul></ul><ul><li>Graphite heat source </li></ul><ul><ul><li>(protects fuel and clad) </li></ul></ul><ul><li>Converter </li></ul><ul><ul><li>(heat electricity) </li></ul></ul><ul><li>Radiator (removes excess heat) </li></ul>
  5. 5. <ul><li>Stirling generator system outputs </li></ul><ul><ul><li>120Vac </li></ul></ul><ul><ul><li>60Hz, 130-140 watt of power </li></ul></ul><ul><ul><li>Continous power supply for ~14 years </li></ul></ul><ul><li>To potentially reduce the amount and cost of fuel(plutonium-238-dioxide) </li></ul><ul><li>To enable cost effective space exploration </li></ul>
  6. 6. HEAT SOURCE STIRLING ENGINE PM-DC BRUSH GENERATOR DC-AC INVERTER DC-DC CONVERTER
  7. 7. <ul><li>HEAT SOURCE </li></ul><ul><ul><li>It acts energy input of the entire system </li></ul></ul><ul><ul><li>Provide temperature difference needed to operate stirling engine </li></ul></ul><ul><ul><li>Output of heat source = input of stirling engine </li></ul></ul><ul><li>STIRLING ENGINE </li></ul><ul><ul><li>Prime mover of system </li></ul></ul><ul><ul><li>Cooling, compression, heating and expansion </li></ul></ul><ul><ul><li>Thermal energy mechanical work </li></ul></ul><ul><ul><li>Output of engine shaft of PM-DC generator </li></ul></ul>
