This is the project page for the 12 lb thrust chinese valveless style pulse jet build video

More information will be posted shortly. The plans shown in this video can be downloaded from the link below:

Valveless Pulse Jet Engine Plans 12 LB Thrust

This video shows how to form sheet metal by hand with a few basic tools in order to make your own pulse jet engine.

The video is a bit long at 36 minutes but has countless helpful tips and techniques you wont learn anywhere else and that will take a long time with trial and error, as well as save you a lot of $

If you’d like to build this engine you can find the free plans download available at :

This is one part in a series of videos, from designing an engine from scratch, to fabricating the stainless steel sheet metal parts, to welding the engine and components, and ultimately running and using the engine.

Here is a screamingly loud TP180 valveless pulse jet engine on a parallel beam thrust measuring rig. The thrust can be computed by determining the angle of deflection. Also check out the echo at the end!

In this video you can see a large ramjet engine being fed high velocity air by a small pulse jet engine. The small engine is not powerful enough to get the ramjet up to a level of high output, but if both were allowed to accelerate the ramjet would most likely produce more thrust than the small pulse jet. www.PulseJetEngines.com

We’re not really sure what the heck this thing is, but it has a really neat flame vortex that forms… is the fire making that noise? is the noise being produced by a speaker to drive the fire into oscillation? We thought it was neat though. You can see a doughnut shaped vortex fire ring form around the back edge of the device, and seem to change shape and size depending on the tone. www.PulseJetEngines.com

In this video a mini pulse jet engine repels debris dropped behind it, pulsejets suck in air through the exhaust pipe during part of the cycle, but only air is able to make it inside the engine, particles have too much momentum to be sucked in so quickly

Here is a short clip of a funny looking pulse jet engine submerged in a big pot of water. The engine quickly causes the water to heat up and boil, and while primitive, is an effective demonstration of just how well pulse jet engines can heat things. www.PulseJetEngines.com

This is a test video of a power extraction turbine positioned behind a small pulse jet engine. Despite the improvised nature of the proof of concept test, the turbine reached up to 3500 RPM at low throttle with the pulse jet engine positioned far away from the turbine. Because there was no load on the turbine, the engine was not run at high throttle, to prevent it from over-spooling and ripping apart. A more advanced setup could be used to power a generator, or other devices. www.PulseJetEngines.com

This video shows a small valveless pulse jet engine vaporizing water into a fine atomized mist, the water explodes into micro droplets when it hits the 500 mph exhaust stream. The path the water takes also demonstrates the flow areas around the engine, notice how some of it gets sucked forward

Here is a clip of a huge cluster valveless pulse jet engine, so far we haven’t been able to find video of it actually running, though we hope to soon. Any ideas what it could have been originally intended for?
