       This project was sent to me from Grant Merriman of Northern Indiana. Grant writes: “Attached are the pictures of my jet engine as it is right now. Currently I am running it on a 20 pound propane tank and using a furnace ignition transformer for spark. I used a stainless steel float ball for an oil tank, works real well and holds 1.1 gallons. I offset my exhaust nozzle up to hopefully supply a little increase in down force when I get the engine mounted to the go cart frame. Idles at about 18,000 RPM. Max Rpm I have run it thus far is 50,000 but I don’t see any problems getting to 60,000 which is where I would like to operate it. Looking down the combustor you can see the evaporation tube that will be used when I start running on kerosene. Currently I run 45 PSI of air through it to keep it cool while I run the engine on propane. Future plans will include an after burner. Thanks for all your help thus far. Grant S. Merriman.....”
