Dad and I were discussing motorcycles one day over Christmas break 2002. He decided that he wanted a jet-powered motorcycle...
Pretty good idea for an old guy. Only problem was, we got kinda serious and started researching jet engines.

Of the four main types of jet engines (ramjet, pulsejet, turbojet, and turbofan), we had difficulty deciding which we should use. All have drawbacks that make them seem impractical.

Ramjets are impossible to use from a resting state, because they rely on expansion of a cool/cold airstream to provide thrust. At low speed, there is no air stream. Apparently, air speed of around 300 mph is required to provide enough usable thrust. Plus, they are not as fuel efficient at low speed. The last is not a big problem, as the bike will only be an exhibition piece, not a primary means of transport.

Pulsejets are so very wrong...They run way too hot. They require complicated figuring to produce enough thrust, or even work (sometimes).

Turbojets and turbofans are way too complicated, and are too big. What's more, they have too much stuff to go wrong.

So, all four types were ruled out...Too bad I'm a genius (I hope). My solution is to facilitate a ramjet. That is, increase the airspeed so I don't have to drive superfast just to make it go. This will be accomplished by installing a small horsepower, horizontal shaft engine on the motorcycle. Attached to this engine will be a supercharger of some sort (design is still in the rough stages, so exact information isn't available).

My older brother thinks I'm gonna get hurt. Wish me luck.
