Step 10: Have fun making lots of noise and shaking the ground while impressing friends and neighbors with your new toy!
1) The engine
2) Ear defenders (ear muffs)
3) Lots of fuel (diesel, kerosine, or jet-a)
4) A leaf blower
5) a washcloth
This is where things get interesting. Firstly you set up the jet in a place where you can actually start it without making anybody mad with the loud noise. Then you fuel it up with your choice of fuel. I like to use jet-a because it just works well and has the right "smell" of a jet engine. Switch on your oil system and set the oil pressure to a minimum of 30 psi. Put on your ear defenders and spool up the turbine by blowing air through the engine with the leaf blower. Yes, you can use electric or air starting on these engines, but it is not the norm, and it is much easier to just use the leaf blower. Turn on the ignition circuit and slowly apply the fuel by closing the bypass needle valve on the fuel system until you hear a "pop" when the combustor lights. Keep increasing the fuel and you will start to hear the roar of your new jet engine. Gradually pull the leaf blower away and see if the engine speeds up on its own. If it does not, reapply the leaf blower and give it more fuel until it does. Lastly enjoy the sound of your new engine and remember to use the washcloth to clean up in case you poo your pants! There is so much power in these engines that it will startle you to the point of losing bodily control.
Videos of our running engines are available as flash movies below. We hope you enjoy them! You will probably need to size your browser down when viewing them so they are not pixelated.
That is about it. Our websites cover all of the build processes and hopefully will get you started on the journey of making your very own jet engine. Be sure to send us pictures if you make your own.
Combustor kits can be purchased by contacting Russ at Bad Brothers Racing. Different kits and configurations are available to help you in creating your jet engine. Fully assembled engines are also available to qualified buyers who sign a release of liability.
