I feel like that was not his first time flying that jet. Very cool.

In highschool my teacher for engine repair class brought in a pulse jet engine that he used to power a 4 foot long model plane with before he wrecked the plane. We had studied various jet engines and asked him to bring his in and let us see it run.

He bolted it to a table, hooked up the fuel tank and then warned us that there was no cutoff and it would run until the fuel ran out (he guessed 1-2 minutes at most). Now this class was filled with some real inner city "tough guys" who were strong enough to not need to cover their ears like I did.

Teacher lights the thing and it fires up with a several foot long, nearly invisible, pulsing jet. Through my hands I could hear the thing humming away loudly and I was SERIOUSLY impressed (actually thinking about how I needed one of these myself). After 10 seconds I look around and the teacher and I are the only ones left in the room. All the tough guys had retreated into the hallway from the noise and flame.

When it sputtered out I asked the teacher how he crashed something so cool. He said, "Line of sight." I did not understand and he explained that a small plane with a really big motor might just climb up and out of your line of sight before you successfully got the thing into a turn to keep it with you. He admitted that the scary part was knowing that he had no idea where the jet was, but that the jet engine was not going to cut out for some time...

BTW: I still need one myself...

Home made jet engines out of turbochargers. A new INGO project?

And Techres, one for you. Haha.

This is like the one I remember:

Not they way I would do it:

Kinda what I had in mind above there!

I really want to make one of those turbo-jets. They're so simple and so cool! I'm not sure i've seen those thermo/pulse jets before.

I've always wanted to make one too. A turbocharger is very similar in operation to the early jet engines, and not that far from today's modern engines.

I wonder if the engines shown are really "jet" engines...i.e. do they really produce any thrust? The one in the car must, but I wonder if some of the others are more like gas turbine engines...where all the power is just in shaft work.

 

[Scutter01]

where all the power is just in shaft work.

That's what SHE said!

Pulse engines have no turbines, just pulsing valves. The only problems is that they have to have high speed air pushing through them to prime the engine. They also are more or less on full or off, nothing much in between.

But pulse jet and ram jet engines really produce super thrust.

And if you wanted to build your own, GPS guided, cruise missile (that is before your government takes note and confiscates it) - a ram pulse jet engine might work well:

This guy must be what my dad was worried I would become when he stopped my estes SAM-2 remote controlled launcher when I was 13. That thing was gonna be AWESOME down at the model airplane park....

I had this image in my head of you shooting down model airplanes with a model SAM...

WOW! doesn't even come close to the excitement that video generated!
Beyond amazing as well.

 

[Seancass]

wow.

I'll be sad if that ever stops being funny.

You got me...of course she likes some "Thrust" every now and then too.
