I am getting geometry flashbacks.

Is that a badly tuned engine I hear overhead?

Going to build a full size operational piloted model?

I do have enough data to make a pretty good mock up but not nearly enough for the guts. And pulse jets are horrible, noisy, massive vibration and sonic shock, and a short function life. The motor pretty-much self-destructs after about a half hour or so. I may well do a static 1/6 scale version however or something similar as a ducted fan flyer.

Plan on starting your own factory?

Getting together data for a scale model

Heck. I'd better get with it. I'm still watching, (And Faving.) your V-2 model building process from about two years ago.

actually, there is a guy in oregon that makes decent pulse jet motors, for motorcycles and lakester cars. impressive, he was on mythbusters. I'd love to see a build full size. I have seen a few of these Rl i9n museums. Im impressed.

If he is the guy I'm thinking of, he's built BIG ones too. The most interesting had two motors in tandem, the second one as a ramjet.

That's the one, and yeah he built ones big enough to push a car about 150mph or so. Beautiful construction work.

didn't the german engines last a few hours though?

Yeah, just reviewed his videos, neato. I was under the impression that the German engines often broke/burned after not much over 30-40 minutes, mainly the reed valves, but the the whole valve assembly could only take so much. The assembly was a sandwich of light alloy castings and spring steel all bolted together. And with a flight time of only about 30 minutes, it was all that was needed. I'd WAG that a beefed up valve assembly might have a bit longer life, and the F-model machines may have been so stiffened up as they had a somewhat increased range and flight time. But with the massively awful fuel efficency, they could only carry so much fuel for so much flight time.

Hey, on Argus IL 109-014 longevity- You were right- I miss-remembered some info and they might well have lasted for a couple or three hours.

A Flakzielgerät 76! Time to reactivate the old barrage balloons...

Yeap, all the wartime German refs are that designation. I'm hoping to do models in various scales. This is primarily a consolidation of all the loose data I've amassed.

There is a ton of stuff available on the internet about these (and the V-2, of course). Good drawings, sadly, are lacking.

My Dad was deployed in the European Theater in the first week of January, 1945 at the end of the Battle of the Bulge. We know that he spent some time as a guard in a brandy-new POW camp the Allies bulldozed out of the Schwarzwald, where he earned his Sergeant's stripes. Somehow, in between, he witnessed an awful lot about Nazi technology. He talked about the development of the rockets at Peenemünde and seeing some incomplete ones there, and several U-Boat pens. He had photos of the sub pens, but they wouldn't let him shoot at Peenemünde. He did have some rather interesting photos of wood-burning trucks (Americans did not invent the Kludge).

And wood-gas vehicles were not exclusively German nor limited to WWII.

So I can see now that you're engineer too <.<

No, just a fair draftsman, can't do all the math needed to be a proper engineer.

maath? 80 of math today done by computer, 10 is within basic calculus course and rest is what called "design consideration" - a total SWAG XD

I just joking

Great video! In school I couldn't get even basic algebra, though some geometry wasn't so bad (visualized), anything more- forgetaboutit.

was there too, before I learned about linear (vector) algebra.. it had so many uses -in geometry, in electricity, in calculus, physics, in modern 3D rendering as most "interesting" application -and had direct represntation in geometry that it helped grasp rest. Thankfully, we had linear algebra in late school, so I had time to accomodate
