Pulsejet-thermojet Engine
Intro: Pulsejet-thermojet Engine
Hello everybody after a long time iam posting a new instructable. Now this is my brand new design expected to produce 35pounds of thrust.
This is my new pulsejet engine made in mild steel 3.5mm thickness the expected thrust from this engine is 35pounds,but still i didnt conduct the thrust test. I will conduct both thrust test as well as TSFC test and post the video as soon as possible.
In this video you can see the engine running at low throttle i didnt upthrottle the engine because at low level itself the sound was too high and neighbours started complaining. So sorry for not showing the full power of the engine. I will post the dimensions as soon as possible.

can u upload its plans\blueprint , how long is the exhaust pipe

What thing are those two little tubes parallel to main?
Did you try it without intake pipe? It is to say, the same tube be intake and exhaust alternatively. I think that must work, and simplifies greatly the making.

The air get in after each cycle because in the inner chamber there is a strong vacuum. You must have a valve in the fuel intake to avoid the backward motion of the fuel. The frequency of the spark plug must be controlled to suit that of the pulses (it can be a multiple).
The flow in the tube will be alternate, but the thrust will be positive, as works the pop-pop motor.
I don't make one of these because I have many neighbors!

I suggest only a very little valve in the fuel conduit to avoid the backward motion of the fuel, but that is not for air intake.

Oh, if you're expecting 35 pounds of thrust, that might be enough to push a small boat!
