I only offer a different way of looking at existing ideas......Waldo

Pulse Jet Powered Motorcycle Cockpit area and rear view showing Pulse Jet engine

    I was running a small desplacement (105 cc) streamliner and having no success with it. I named this streamliner "Defiant " as it always behaved like a bad child. Frustrated I removed the drive train, mounted a load structure on the rear and installed a Propane fueled, valveless pulse jet engine of 90 pounds of thrust. It was eight feet long and was as light as a feather.

   The engine was originally used on target drones. I don't know how though as it was about as dependable as a Heroin addict. It ran well on the static stand but would go out of pulse (which was about 60 cycles or explosions per second) if you so much as looked at it wrong. It was quite a site though as the stainless steel engine got so red hot you could actually look through it. Even rocket engines aren't as violent as this thing. It made a lot of noise and scared the Hell out of anyone near it as it looked and sounded like it was about to explode at any second. I would put my hands into the flame and talk about roasting weenies as it was screaming, blamming and throwing sheets of flame. Even with ear protection on you could barerly think as it is so loud. Imagine standing next to an eight inch diameter cannon firing
60 times a second. Amazingly, this is a valveless pulse jet and cannot explode as it's combustion chamber is open all the time. It is a popular design called the tuned pipe design. It would start with a huge BLAM when it first lit which you never got used to no matter how many times you ran it. Then you babied and coaxed the fuel until it felt like it wanted to pulse which most of the time it didn't or would stop soon afterwards.

   Trying to campaign the liner was just too much aggravation for the fun it supplied (Hardly any) and I dismantled it and gave the pulse jet engine to Bob Lazar. I tried a great new aerodynamic idea on this liner though as I used two large fins mounted at the center of gravity of the bike forming a butterfly tail. These would stabilize the bike really well but in a cross wind they would really keel you over especially at any good speed.
