  1. Converting an R/C Aircraft Engine for use with Hydrogen FSU Senior Design Group 13 Greg Smith, Travis Watson, Joshua Mardis, John Lubatti Sponsor: Ken Edwards, Eglin/AFRL Faculty Advisor: Brent Greska

  2. Semester Goals • Build Mounting System • Test using both Nitromethane and Hydrogen • Modify as needed and re-test • Make Recommendations and Proposals for further study and design

  3. Our Engine O.S. FS 70-II Surpass 4-Stroke Engine

  4. Mounting System • In order to Successfully Test the engine it needs to be securely mounted • We tried to test it by clamping the engine down, but this has proven un-successful.

  5. Mounting System • Currently in the Process of Constructing a more rigid mount for our engine

  6. Testing Flowchart

  7. Lubrication • Oil will be provided through an access hole and closely monitored during and after each run • Currently Researching the use of a Graphite Lubricant for the Rocker Arms

  8. Fuel Delivery System Initial Setup Proposed from last Semester’s Design Report - Use the Carburetor

  9. Fuel Delivery System • If time permits, a makeshift direct injection mechanism (non-electric) will be designed and implemented. • This will consist of a pressurized hydrogen storage tank connected to a check valve, which is connected to the chamber through tubing with a diameter smaller than the quenching distance of hydrogen.

  10. Fuel Delivery System • A check valve will be used to allow flow into the cylinder during the compression stroke to eliminate backfire and improve volumetric efficiency. Courtesy of www.checkall.com
