Most pulse jet designs I've seen spray the fuel into a diffuser ahead of
the valve.

Go to: http://www.pulse-jets.com/ for some useful information on pulse
jets. It has drawings of several different models of pulse and pressure
jet, including the Argus. They also have a fairly active moderated forum.

Hi, im building my first pulsjet. I have calculated dimentions for 78
lbs ( 35 kg metric ) of thrust.

Here is the dimentions:

Exhaust pipe diameter : 5 Inch

Exhaust pipe lenght : 34.11

Combustion chamber lenght :11.34
Exhaust cone lenght :11.34
combustion chamber diameter 7.28

I am going to use argus type valves.

The plate that the valves rest against has 5 slots measuring 45X17
milimeters.

There are 4 of these plates, two of them forming a "V".
It is two of these "V"s velded to the front plate that has 2 holes
measuring
41.92X144.21 milimeters.

The angle between eatch plate of the 2 forming eatch "v" is 31 degrees

The valves are overlapping 3.4 mm of the edges in each slot cut in the
valve resting plate.

For fueling i am planning to use 3 steel tubes drilled with small
holes so the fuel can enter the combustion chamber.
These vill be located 3 inc deep in the combustion chamber.

So if anyone has some opninions on my design, ill be glad too hear.
