There was once a Atomjet ...
hello friends, this time (after a loooong time) come with the continuance of an engine, Atomjet (with valve) ... I watched the plane and I'm not agree with their actions, so I'll do 2 nozzles, one as says the plane, and as I think can do better.
for the moment I'm finishing with the original nozzle, which according to calculations I should work, not harnessing the full potential, but would walk without problems ...

Re: There was once a Atomjet ...
Looking Good Francisco, (as allways) nice work ,
I experimented with different fuel nozzle designs , and found it difficult to better the Dynajet style , but I dont have a lathe and I am sure there are other styles that may be much better , please do post some updates , good to see you back here

Re: There was once a Atomjet ...
hello, Grim!! I am a little worried, this forum is not like in those years 20003, 2004, or 2005, where he was showered with post! hehe, but well, I think all we're always the forum, but few answer ( me).
in the design of the nozzle, if there are a couple of methods, and more efficient (that is my preference kb70) but hey, it will first show that this engine, then we make the change!
Thanks for your Re welcome! at a time to be publishing some more of the engine.

Re: There was once a Atomjet ...
this pulsejet its run!! its run!!! tomorrow up pictures and videos! its a great enegine.
Re: There was once a Atomjet ...
Congratulations! Looking forward to the pix and vids!

Hi francisco,
Any information on a video?
Good work on a beautiful Atomjet.

Re: There was once a Atomjet ...
Guys! i provided this pulse.jet a friend... 2 day ago, this friend retun with my pulsejet.... here is the vidio!!
now.. 2 cuestions
1: in the tail pipe, le cone of fire is organe.... but it should be blue... right??? where is the problem?
2: the tank of fuel must be very higth... what inyector i should change???

Re: There was once a Atomjet ...
Hi francisco,
If the body/duct is a mild carbon steel the exhaust color is supposed to be orange. The engines slowly burns the carbon from the steel and makes the exhaust orange. It looks near perfect to my eye. What is the number and size of the fuel holes? Any valve petal damage (they look only dis colored)? Fuel was methanol? Beautiful work.
Many thanks for posting, Joe

Re: There was once a Atomjet ...
Joe! yes! the tail pipe is a carbon stell.. but, i rememeber that i used this motor 1 year ago, and your flame was blue... i dont remember what inyecter used...
on the video, i use a inyector whit 2 holes of 0,5mm. and one adapter of 2mm in the front.
I use a Gasoline and Kerossene 50% and 50%
then of 10 minit of use.. the valvele is very nice!! whitout damage...
Sorry for my English

Re: There was once a Atomjet ...
Perhaps your flame color is partly this if you used the same gas/kerosene fuel both times.
(Flame color)
"In the most common type of flame, hydrocarbon flames, the most important factor determining color is oxygen supply and the extent of fuel-oxygen pre-mixing, which determines the rate of combustion and thus the temperature and reaction paths, thereby producing different color hues."
"In a laboratory under normal gravity conditions and with a closed oxygen valve, a Bunsen burner burns with yellow flame (also called a safety flame) at around 1,000 °C (1,800 °F). This is due to incandescence of very fine soot particles that are produced in the flame. With increasing oxygen supply, less blackbody-radiating soot is produced due to a more complete combustion and the reaction creates enough energy to excite and ionize gas molecules in the flame, leading to a blue appearance. The spectrum of a premixed (complete combustion) butane flame on the right shows that the blue color arises specifically due to emission of excited molecular radicals in the flame, which emit most of their light well below ~565 nanometers in the blue and green regions of the visible spectrum."
"A blue-colored flame only emerges when the amount of soot decreases and the blue emissions from excited molecular radicals become dominant, though the blue can often be seen near the base of candles where airborne soot is less concentrated.[8]"

Re: There was once a Atomjet ...
Hi there Francisco
I recently subsribed to your channel and asked the question 'did you build these yourself?'
Anyways brilliant engine, nice effort. Iam planning to build a valved dynajet in the future for an rc plane. I will learn to fly first though.
Looking forward to more info and videos!
Your English is fine, your English speaking is better than most Englishman Haha

Re: There was once a Atomjet ...
hey!! i see your pulsejet! nice too!! this motor is built to me... i can help you to buil... what machine have you? if you want some part of the pulsejet, i can send!
regards!
oh!! yes!! i need you help whit my English!! its really important!
