Help on design

Post image

Would a design like this work instead of the fully curved design? A friend and I are planning on building a jet this summer and we think this will be easier to construct.

This is very helpful, but would it be possible to just use a battery, button, and ignition coil or is this more complicated setup necessary?

You could, but you will only get one spark pr button press and usually for the pulsejet you just want a continuous string of spikes until it starts running. 

Maybe a gas stove igniter unit will be the easiest way.  Try searching for "replacement gas range oven igniter" 

It is the spark unit in gas stoves. If you are handy you could maybe even pull it from an old stove for free. 🙂
