The concept of Pulsejet has been quite fascinating for me.
I wanted to make a small pulsejet but did not have the proper tools and
materials. Further, I am not good at working with sheet metal. Nevertheless, I
wanted to make a small experimental pulsejet. I live in a city called Chennai,
which is in southern part of India and is quite well known for its steel market.
So, finding appropriate materials for building the pulsejet was not a problem.
Further, I befriended a lathe shop owner. He seemed to be quite excited on what
I wanted to make and offered his time and his lathe machine for making parts.
The next logical step for me is to draw up a plan and collect the required
materials. Why make a pulsejet? Well, that is exactly question that asked myself and I came up with these possibly convincing answers. 1, Concept of pulsejet is quite interesting that I wanted to make one 2, I wanted to make an alternate propulsion mechanism for my model aircrafts 3, There is something obscenely attractive to make such a loud and heat producing machine. How did I go about it? I searched the web for sites that could educate me in making a pulsejet. I was lucky to find a nice tutorial on making pulsejets. Then, I found an excel spreadsheet that could calculate the dimensions and provide the critical parameters in making the jet. You can find more details on pulsejets at www.pulse-jets.com So, far I have made two pulsejets – Mark 1 and Mark 2. The first jet (Mark 1) is a small pulsejet and it ran only with a constant supply of air blast. The second jet (Mark 2) worked fine. The details and the build thread of both the pulsejets could be found on the links above. If you are attempting to make a pulsejet, then I strongly recommend the following links Inside pulsejet by Fredrik Westberg Pulsejet engine - Design calculator Bruce Simpson - The missile man And finally, check out Bruce's video on how pulsejets work
