will this idea work?
 

I have been messing around trying to make a kind of ramjet that will run without moving. I know this isnt a true ramjet but here it is. I made a system with a electric ducted fan in the front. I then drilled 3 holes just in front of the fans and hooked up 3 fuel intakes connected to a carboraterthen the fuel tank. when i get the fan going it sucks fuel up the lines from suction and i can make the carb works good and i can control excactly how much fuel goes in, i can make it to the point where i put my hand in the back and its soaked, or i can make it an extremely light mist . What i am wondering is how i can get it lit. And will a mist of fuel light up or am i just wasting my time. last questian, what kind of fuel should i use? right now i am just using water to get a reliable constant mist of fluid and i have it right on now. Thanks

I would use 92 octane gasoline and a bic lighter to ignite the air fuel mixture.

i have a link to video of it running somewhere, I'll have to find it. Ram jet made from an insulated mug shell.

thanks for the link, would 92 octane fuel light quick enough? it seems like regular gasoline wouldnt stay lit very well, but i could be very wrong. i was thinking about just using 35 percent nitro fuel. a zippo seems like a good idea to light it, but worried bout blowing myself up :) . thanks for all the help!

get rid of all that liquid fuel and use Propane. Once you get that to work then go to the gas.

I have build a number of combustion chambers with alpo cans and electric blowers and propane..Great fun

i was acually trying to stay away from propane (seems like a lot of hassle and expense). But if i cant get liquid to work i will try propane. Eventually i want to make one for rc, this one is just to learn the basics. thanks for your help and suggestions!

This guy might be interested in it as a next research project.
You and him should get together and compare notes.

why do you say that?

r3tic,
Looking forward to seeing the video

Sadly, I am unable to find the video at the moment. I was able to locate the construction article which has pics of the jet running.

There are three pages all together.
