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
