simple pulsejet

hello everybody,today iam going to show you how to make a simple pulsejet which costs around Rs.50..This consists of three pipes and some welding experience..I think this is the simplest pulsejet you can find in the net..here are the plans available for you to make..

note: please flare at the end of the intake pipe..

I'm sorry I can't respond to you answer ganuganu because it won't generate the "spam reducer", but I have another question, is welding safely in anyway dangerous, because I have begged my mom to weld, but she calls it "dangerous"! I can't weld whatsoever, until I take a "safety course" (which doesn't exist)

[ganuganu]

I dont know your age and your experience in welding. If you dont have any experience in welding then dont do it. Because it is dangerous. Try to buy some threaded pipes and fix it together so it solves the welding problem.

Thank you. Sorry I didn't say my age. I am 14

That's a nice build! I can't weld, so instead of welding, could you sweat solder the jet together? I've gotten into pulse jet engines, and would like to build it!

[ganuganu]

Its better to do welding rather than sweat soldering because the welded part should be able to withstand high pressure and temperature. If you would like to build one try to build this http://www.instructables.com/id/easy-pulsejet/ its an improved version and very easy to start.. Thank you

hey hiii!!!! ganesh this is pradeep ... your work on the pulse jet engine is excellent....
i recently made a pulse jet engine but the combustion is not taking place ... its not self sustaining .... here r some pics plzzz find the problem in that ... cause im in a great need.. ill try to upload the video as early as possible ... by the way dimensions r given below

Is it possible to run it on gasoline or something like that

[ganuganu]

yes ofcourse you could use.. but you need fuel pump to inject fuel at high pressure.

That was a hell of a bee.

Wow, that's pretty cool that you made a working pulsejet so simply.

[ganuganu]

thank you..

Have you tried measuring the thrust?

[ganuganu]

yes i tried.it was around 1.5 to 2 pounds of thrust..

[Kiteman]

Cool.
