My First Valved Pulse Jet
Well I built my first 10lbs Valved Pulse jet following the design calculations of Eric Beck Calculator..... I have used the aspirated engine approach! When I tried to start the engine by blowing air inside using an air-blower, powered on the spark plug through a driving circuit based on an automobile ignition coil and sprayed some gasoline continuously through a small refrigerator copper capillary.......but I couldnt start the engine........... Worst of all it didnt even created any sound or bang!! I am at my wits end now! Whats the problem here??? Plz help me on it because I really want this thingy to work!!!!
Re: My First Valved Pulse Jet
does the fuel ignite? What's the frequency of your sparks?
Quantify the world.
Re: My First Valved Pulse Jet
No! The fuel does not ignite! Well my ignitor should provide round about 8 sparks per second (8 Hz freq.) with 66% duty cycle!
Re: My First Valved Pulse Jet
It works! Its buzzing! WoW! thanks...opening the gap did the trick.... but it seems like I was also spraying a very small amount of fuel!
