Building a pulsejet engine for 110 rupees

[ganuganu]

This is the simplest pulsejet you could make and costs only Rs.110 and has got a good throttling range,which you could see in the video..No need to strain much to start this engine it starts in a single attempt..If anyone need to make this design please reply here..Thanks for watching see you all in the next pulsejet video..

This is great! I remember as a kid trying to build a reed pulsejet... Got as far as cutting the reeds by coating spring steel w/ paint and scribing lines / reverse electrolysis machining the metal.

I'd be interested in seeing dimensions / plans - perhaps I can build one for fun one day!

Thanks,

George

this is valveless so no problem for us,no need to make valves..here is the design..All dimensions are in cm..Those are standard pipes so readily available in markets..

note: place the inlet fuel pipe at a depth of 4.3cm into the intake pipe..The fuel pipe dia is 3mm..

this has really got good thrust,tried to show an cloth near it but i was not able to do it,so much of force from the exhaust pipe..one day i will hook it up to a scale and find out the real thrust..

note: at the end when i tried to show a cardboard the engine got few holes in the welded parts..
