A pressurized environment for the PJ

In the “turbines driven by pulse jets” topic: http://www.pulse-jets.com/phpbb3/viewtopic.php?f=18&t=5269 I started to wonder what would need to happen to a pulse jet’s geometry to have it working in a pressurized environment. That’s not pressurized feed of the intakes but a (much) higher ambient pre...

Re: Turbines driven by pulse jets

Viv, and everybody else, In the meanwhile I can’t get my thought’s off the pressurized environment for a PJ. I might even have a purpose for it or a way to use it. :D :D But my knowledge of pulse jets (specially in numbers) is to little to predict what’s needed to have a PJ working in a pressurized ...

Re: V8 thermojet

Eric,

Shameless advertisement, haha :lol: :lol:

Now, I already have my own, fully welded, thermojet. I posted the above because of the idle running of that thermojet. It runs idle like a V8 :D :D
I want to make mine also run idle like that.

Re: Gassifier Gas?

Rossco, Very clear now. Most times it's pretty easy though to recognize the impossible "mechanisms" because they claim in fact to create energy. It all comes to: NOBODY CAN CREATE ENERGY You can only TAKE energy from somewhere (for ex. a fuel, waste heat) where it is to be taken. I remember all the ...

Re: Anyone *build* a cyclical flow jet engine?

Hi everybody, I don’t know much about aviation, rocketry and space. That’s why I ask the following questions: What is the steepest climbing angle in which a wing still provides lift? Does it depend on speed? What is the highest altitude where lift can be obtained? I was thinking of the following: A ...
