Thanks for the help. The part about the retainer plates makes sense.

Did I read the caption on the image right? You said you used razor blades for the valves?

Thanks again-

MK-
How did you fasten the spring steel to the valve plate? Also- I am probably wrong but wouldn't the valves not carry enough momentum to go past a line parallel with airflow? I would think the retainers would not be necessary because the valves move a lot less then petal valves.

Hmmm- I have very little experience in circuitry like this. It will take me quite a while to fully comprehend what you are speaking of. I was hoping for a simple solution like a manual valve but as the saying goes "anything worth doing is worth doing right." I am reading the links you posted and am ...

Fuel Control

I have been fishing around in junkyards for fuel injector parts to fuel a pulsejet with 25lbs of thrust. I have realized that the entire time I have just looking for the pump and the injector. Have I overlooked a way to monitor fuel flow? The magnetic switch in the fuel injector can start and stop f...

i ran into the same problem. DIY stores didn't want to sell me a propane line w/o a regualtor and offered absoulutly no help on how to solve the problem. For mine i bought a 5 foot hose that is meant to adapt natural gas from the house to a propane grill. I also bought the type of propane fitting th...

Fun with Latex?

Tupperware just came out with new pans made of some latex type stuff. They come in all sorts of shapes and sizes and are about a quarter inch thick. My mother is obsessed with them because she can’t get over putting rubber in the oven and it not melting. Is there any use? I dont have a clue how mu...

Pop Sci Ramjet

I have a friend who talked about a ramjet design in Popular Science that could run stationary. Anyone have a clue what he was talking about?

I realize that the air "drawn" through the front would have little (read: no) acceleration due to thermal expansion like what you are talking about in normal augmentors. BUT here's what I was thinking- As the air bypasses the jet it will absorb quite a bit of heat it would by no means be as hot as t...

Dual Augmentors and Air Cooling

A friend of mine builds hovercraft as a hobby. We want to make a jet propelled version but safety has become a real issue. If the thing catches an edge at high speed it will most likely flip. The problem is that we would have to mount the engine low for balance reasons and far too close to the drive...
