I'll build a new one with more care.But do it have to be very noisy to say that it's running?It was more quiet then a 2.5 model airplane engine.

I tried the engine with butane.The nossle was from a torch so I didn't have problems with the air/fuel mix.It was no problem to get it...well I don't know what exactly.It sounded just like a pulse jet but it wasn't very loud and it didn't have a trust.What do you think was it a jet or more like a no...

I extended the tail pipe and the intake.The tail pipe is 2,1 santimetars the chamber is 5,3 and 10,2 santimetars.I suppouse that I have no restrictions for the tail pipe lingth.I have some leaks.The eqivelent of 2mm straw.With these wide tubes why so smal leaks can be so bad.Why there is an intake p...

Waht's your's apinion?Will I be able to get this running.I realy wan't to have a jet engine. The volume of the tube is eqal to the volume of the chamber.

I made a valved engine with a very light valve.It was clasical shape.I filed the chamber(not all ofcourse) with acetone, turn on the spark and blow some air in.It didn't work more the 1s :( .I suppous that after few combustions, there are not enough vapers in the chamber and that's why the engine st...

I have experiance with spud guns and I know that the gases from a torch are just the right ratio between the butane and the air.If I make very small valved engine with very light valve do you think I'll be able to start it easy?Also from spud guns I noticed that the metanol is allways the in the rig...

If I take a car carburator or homemade carburator and put it in front of small valved engine will I be able to start it easily?

I won't but what do you think?Is the valved jet easyer to start then the valveless

My poor experiace with puls jets tells me that the valveless is much harder to start.Am I right?

Sorry for the stupid question, but can someone give me a link to 'how the pressre jet works',please.Or is it just a big torch?

I had a pain in the ears after playng with my mini spud gun with O2 and acetone as fuel.

Is it possible to start a valveless with O2 only(no comprest air).Just hit the ignition and get it running.

Can some one tell me how to make an engine(no matter what kind I just want it burning).I'm 15 years old and I have no welder.I have expireance with solid rocket engines and spud guns.I can't start my 'engine'.I was useing metanol.I have some O2.Are the preshure jets something like a big torches?

What was the fuel that you were using?For damage I advise you aceton peroxide.Don't handle with out an eye protection.May be a coposive chrge will do the job. :D

This is a very easy way to get hidrogen. Al+NaOH+H2O=>NaAlO2+H2
try to put NaOH, pieses of jar cover(or other Al pieses) and H2O in a beer can.You will get a steem and H2.
