Perhaps this is a good time to remind all those who are experimenting with, or who plan to experiment with these engines that you really do have to be careful. Accidents can happen in the blink of an eye and may lead to serious or even fatal consequences.

One of the newest and most exciting areas of pulse-jet development is the

Pulse Detonation Engine (PDE)

You should always have a fire extinguisher handy and be aware that working with these home-made turbines is not without risk of injury or even death.

The risks of containment failure (ie: a catastrophic explosion that turns your engine into a grenade) and the difficulties involved in obtaining reliable detonation of readily available fuels make both dangerous and likely to be quite disappointing.

The sad truth is that you're unlikely to be able to coerce a mixture of gasoline and air or propane and air into true detonation using something you've built in your garage -- and if you do, the paramedics will likely have to take you away in a plastic garbage bag (that's if they can find all the pieces ;-).

A Lockwood Valveless Engine

An engine that is as simple as a ramjet having absolutely no moving parts.

Bruce Simpson's Big Version The Lockwood-Hiller Design

The picture on the right is one of the Hiller-Lockwood prototypes being tested. This particular engine is said to have weighed in at just 30 pounds and produced around 300 pounds of thrust. Note that most of the engine is glowing with the heat produced. Also note that it appears as if the guy in the background thinks his hearing protection is inadequate.
