More about our computer model

[Alex Eng]

We've published a detailed description of pulse jet engine mathematical model implemented in our program. Perhaps someone will find it useful or interesting.

Here's the article.



It's a real scientific article, very long and detailed; we believe it's a record for the volume of such articles (45 pages - almost like a book!). Nevertheless, the Canadian journal "Drones and Applications" didn't even cut it. For this, we extend our special thanks to the editors.

Currently, everything is described there as it is made in our program. However, some processes require further development and refinement. For example, we really want to replace the piston analogy model for gas flow in a resonance tube with a one-dimensional compressible gas flow model. We're already working in this direction. We also want to refine the flow model in the inlet device, as well as the reed valve motion model.

Unfortunately, all of this will take a significant amount of time. Therefore, we will do it gradually, as best we can.

Just for information .

Very nice work! It makes me want to model my pocket jet valveless in it and see what it says.

Dear Mike, thanks a lot, you can try to do it. It is interesting, if some variant will work up, we would be very grateful for your information about results.

We have a real problem now: for a year, from switching on the program for everybody, we received no one comment about it. Factually, we don't have feedback with our program. We understand that now the topic of pulsejet is not interesting for anybody. Absolutely and on 100%.

The reason is very simple. Now the turbojets are on 100% enough for all and everywhere - from modellers till great aircraft engine companies. But. Turbojets have 1 serious drawback - it is impossible to produce them by mass production, thousands of engines per month.

If you know, we have now absolutely stupid and bloody war in Ukraine, where dozen thousand Russian soldiers-zombies under dictator Putin's order are rushing at us like zombies from "World War Z". Under these conditions, we need cheap, mass-produced weapons, for which such a wonderful and already warm for everybody turbojet engine is completely unsuitable.

Therefore, any advice or offer concerning our program would be very useful.
