BIG Valveless Thermo Pulsejet

"A pulse jet engine (or pulsejet) is a type of jet engine in which combustion occurs in pulses. Pulsejet engines can be made with few or no moving parts, and are capable of running statically." en.wikipedia.org/wiki/Pulse_je...
FAQ:
Where did you get the plans?
- No plans, just good estimates. Dimensions were estimated from various youtube videos and online demonstrations.
What is is made from?
- 1.6mm 316 stainless tube. Exhaust is 2.5", 6" combustion chamber, 1" intakes.
What does it run on?
- Propane gas. It has 3mm diameter gas nozzles.
Thrust?
- Don't know, haven't measured it.
How loud is it?
- It's rude. Will measure one day.
What's its purpose?
- Wanted to build pulse jet. Science and engineering is cool.
Future plans?
- Thrust augmenter, mounts and platform for thrust tests.

Nice job, good throttle range too

[@apismellifera1000]

Thats a nice very well put together engine. Nice welds and nice wide throttle range

[@american7169]

I like it, want it just to piss the neighbors off!

[@jonohawkins]

I love u fellas! That is so badass. Look u get me some type of heat treatment for my back..... and some roller skates....... we are gunna have a good time!

[@illumiNOTme326]

Great work man

[@BeckTechnologies]

Very cool, nice job.

[@Scoobydug]

Let's see that strapped to Jason's cruiser

Pipe dimensions are in the description.

Beautiful craftsmanship on the fabrication. Congratulations on the extreme throttle range. Tell me, how much thrust you think you're producing? Also would you tell me the diameter of the exhaust the diameter of the 2 intakes and the diameter of the combustion chamber. I'm planning on building a Chinese designed pulse jet up in the 50 pound thrust range. your dimensions would help me immeasurably. Thank you in advance. John

Which material used for casing.?

[@sharanpujar6268]

what did you use to ignite it?

[@jotarish2]

Just a sparkler. Sorry, i just saw your comment.

[@sharanpujar6268]

i used your plans and made a smaller one but its not starting

[@jotarish2]

LAZY PATRIOT I also used compressed air down the inlet, they can be a little temperamental until they warm up, maybe try shrinking your fuel nozzle size down a bit .
