very cheap ~1 pound engine for sale

Post by metiz » Wed Mar 24, 2010 4:21 pm

This is a small pulse-jet that will push about 1 pound. It has been designed for the sole purpose of easy construction and therefore I can sell it very cheap.

The combustion chamber is made from 0.5mm stainless steel
The flat plate blocking the combustion chamber is made from 1mm stainless steel
The intake and exhaust are made from 2mm stainless steel.

This engine does not have a sparkplug for a number of reasons. If you are in the market for an engine like this, it's likely that you do not have an ignition system lying around. A sparkplug would also increase the cost of this engine and it needs to stay as low as possible. You will be able to start this engine using simple firework sparklers wich you can get in any toy store. Just light the sparkler and throw in in the combustion chamber. turn on the gas and apply some air and it will start up easily. Please note that although this engine is probably small enough to run of a propane tank with a regulator, if you want full power you will need to get some direct feed couplings. (I paid about 5 bucks for those components, including shipping)

For ease of use, the injector is welded on the exhaust pipe. The injector has a Rosscojector tip, an internal diameter of 3 and an external diameter of 4mm. The injector is positioned 30mm inside the intake.

The main purpose of this engine is to entertain and demonstrate. If you are interested in pulse-jets but you do not want to spend a lot of money on buying one or don't have the time to build one yourself, this is the engine for you!

Runs on propane
Good throttle range
Injector welded on engine
Easy to start
Although small, very loud and hot!
Thrust ~1 pound


Asking price: €45 Excluding shipping.
I accept payment through paypal or if you live in the Netherlands, though a money transfer. If you want to pick it up yourself then there are no shipping charges onviously.


DISCLAIMER!

pulse-jets are VERY loud and VERY hot. hearing protection is MANDATORY and it is advised to run this engine away from heavily populated areas. The heat produced by these engines will burn anything that comes close, including skin. Be VERY carefull, it is not a toy.

By buying this pulse-jet, you take full responsibillity for any and all damages done to people animals and property
