hmmmmm, thanks larry...........

what kinda flame holder problem could cause this??????? not letting enough air through??? to much air???? i doubt that.... im going to make sure my airflow is straight across...... now why do you think i have enough air flow? shouldnt there be blue flame out of my tail pipe??? not the white flame i ...

i got my best run yet on you tube now. sorry it is the only way i can post vids as of right now.... the video is the one that is 4 min 33 secs long. it is running on liquid map gass, though it seems i aint getting enough air in my jet. any sugestions on a better blower, or a better air supply? id su...

the reason i ask is on my last run, my ram jet kept pulsating. now i know it has nothing to do with hormonics at all however, but it did pulse regularly until the drop in fuel pressure disrupted this.... a vid will be on you tube with my others tomorrow....

in this video my cc was too short, and i had a large washer in the rear of the tail pipe just as a way to play around with different configurations. the washer keep wanting to be the flame holder, aslo i have lots of flameouts because my fuel pressure keeps droping and the blower is too close for th...

my vids are up on you tube finally.... here is the link...

tell me what yall think :)

they are in the science and technologies listing then click search and type in jet, my engines are under rednecks jet engine

well technically, if it never reaches the sub atmospheric, there is no kadency breathing involved and that makes it a pulsating ram jet. right???

thought i would bring this thread back to life as i have learned alot since.....

so im not the only one thinking of using an rc ducted fan. here is the thing about the ducting down the blower. i dont think it will matter so much, i think that a ram jet needs an amount of air moving at high speeds through a duct the same size as the difuser intrance. you could make the air moving...

i noticed a kool thing about my engine, my pressure manifold works in an interesting manner, at low air speeds, the pressure manifold acts as the flame holder and the area between the flame holder and the pressure maifold act as a mixing chamber. Then as air speed increases i hear a loud backfire, f...

wow you shut us down, we are all speachless. that is amazing dude, i think you blew everybody away cause nobody is posting right now. i just hope people arent loosing interest in this thread. i have modified my jet again, making the cc a total of 3.8 inches long, from the primary flame holder to the...

i want to know how to figure out how much air can be sucked through an augmentor of the same area as the exhaust pipe on an engine. obviously it will depend on the exhaust velocity but i still need to know, is there a ratio or formula i can use? is it just a percentage? how do i figure out the corre...

hey guys.... guess what? I FREAKIN GOT THRUST!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! i modified my cc, makin it about 3 inches long, using aluminum flashing of all things. for about a minute run it held up pretty good. i was running it on gas propane then turned the bottle upside down. the motor drank i...

how good a cc would 28 gauge zink make?

well jim, neither of my jets have any heating problems. though i know they get really hot because a head bolt off of a car that i am using down the center of my jet gets red hot. the reason my casing stays cool i do believe is that i have really good laminar air flow across the inside surface. i hav...

oh ok jim.... lol i reckon i didnt read you right. im sorry. just when you said that since i am so good at this..... ( as im not really ) i figured yoiu were makin fun, but oh well. sorry for the miss understanding. as for the 50 mph ram jet, i have one i built that runs off of a blow dryer. its rea...
